Release 4.3.5 26th March 2023
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
- fixed 32 bit microsecond wrap in BDShot code
|
|
|
|
|
|
|
|
|
|
This release has a single bug fix for a critical bug for anyone using
|
|
|
|
|
bi-directional DShot on their vehicle. If using bi-directional DShot
|
|
|
|
|
and the vehicle is running its motors when 32 bit microsecond time
|
|
|
|
|
wraps at 71 minutes (or multiples of 71 minutes) then the bug that is
|
|
|
|
|
fixed in this release has an approximately 1 in 3 chance of causing
|
|
|
|
|
the motor to stop.
|
|
|
|
|
|
|
|
|
|
Note that the time is the time since boot, not the time since arming,
|
|
|
|
|
so even vehicles flying for a short time could be vulnerable if they
|
|
|
|
|
sit for a long time on the ground before takeoff.

Release 4.2.1 23rd May 2022
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
This is a minor release on top of the 4.2 firmware. It has a number of
|
|
|
|
|
bug fixes and safety improvements. The changes are:
|
|
|
|
|
|
|
|
|
|
- fixed a bug in handling wrap in log download when 500 logs are on the microSD card
|
|
|
|
|
- added FlyingMoonF407 and FlyingMoonF427 support
|
|
|
|
|
- fixed RSSI input on the RCIN pin on CubeBlack and CubeOrange
|
|
|
|
|
- fixed update of gyro FFT throttle tracking
|
|
|
|
|
- removed unhealthy reporting on airspeed sensors with negative pressure as this commonly happens on VTOL takeoff
|
|
|
|
|
- improved handling of large LOITER_TURNS mission items, expanding maximum to 2.5km
|
|
|
|
|
- added fuel usage integration on Lutan EFI
|
|
|
|
|
- refuse arming in AUTO when in a landing sequence due to a failsafe
|
|
|
|
|
- account for sprung throttle (from RC_OPTIONS) in throttle suppression code
|
|
|
|
|
- improved safety of in-flight compass learning
|
|
|
|
|
- fixed automatic airspeed ratio calibration for 2nd airspeed sensor
|
|
|
|
|
- increase safety of GUIDED -> AUTO takeoff sequence used by QGC
|
|
|
|
|
- added CAN_Dx_UC_ESC_OF parameter for ESC offset for bandwidth efficiency
|
|
|
|
|
- fixed handling of safety state on boards with no safety switch
|
|
|
|
|
- fixed bug where a false positive could trigger landing disarm while land repositioning is active
|
|
|
|
|
|
|
|
|
|
The most important fixes are related to how QGC (which is often used
|
|
|
|
|
on modern GCS style transmitters) does automatic takeoff with the
|
|
|
|
|
"swipe right for takeoff" system. QGC does a sequence of a change to
|
|
|
|
|
GUIDED mode, then arming, then change to AUTO mode. That sequence is
|
|
|
|
|
dangerous if the current waypoint is not properly reset to a VTOL
|
|
|
|
|
takeoff. To fix this a number of changes were made to ensure that
|
|
|
|
|
takeoff is done with a valid VTOL takeoff. The changes include
|
|
|
|
|
handling of failsafe events (such as GCS or RC failsafe) part way
|
|
|
|
|
through this takeoff sequence. If QRTL or RTL is engaged during this
|
|
|
|
|
sequence then the vehicle will switch to QLAND.

|
|
|
- fixed H7 FIFO issue with RTSCTS flow control on UARTs
|
|
|
|
|
|
|
|
|
|
- apply takeoff throttle slew limit in TAKEOFF mode and forward
|
|
|
|
|
transition in quadplanes
|
|
|
|
|
|
|
|
|
|
- reset target mission airspeed on disarm
|
|
|
|
|
|
|
|
|
|
- added RC_OPTION bit to enable multi-receiver systems
|
|
|
|
|
|
|
|
|
|
- don't apply fixed wing pitch limit to tailsitters when hovering
|
|
|
|
|
|
|
|
|
|
- fixed turn rate coordination when inverted in fixed wing flight
|
|
|
|
|
|
2021-10-17 01:49:46 -03:00
|
|
|
- fixed bug in AUTOTUNE mode that could leave gains from part way
|
|
|
|
|
through the tune
|
|
|
|
|
|
2021-10-16 06:02:58 -03:00
|
|
|
Of these fixes the only one that is not backwards compatible is the
|
|
|
|
|
new RC_OPTION bit which needs to be set if you have multiple RC
|
|
|
|
|
receivers on your aircraft and want to fail over to a backup receiver
|
|
|
|
|
while in flight. You will need to set the new RC_OPTION to enable that
|
|
|
|
|
for the 4.1.2 release and later.

- added automatic backup/restore of parameters in case of FRAM
|

corruption for F7/H7 boards with 32k FRAM parameter storage
|
|
|

|
|
|
|
- fixed a bug in EKF2/EKF3 that could cause memory corruption if
|
|
|
|
|
external naviagtion sources (such as vision based position and
|
|
|
|
|
velocity data) is supplied before the EKF has initialised
|
|
|
|
|
|
|
|
|
|
- fixed a problem with low accuracy data from UAVCAN GPS modules when
|
|
|
|
|
GPS blending is enabled
|
|
|
|
|
|
|
|
|
|
- fixed an arming check failure with u-blox M9 based GPS modules
|
|
|
|
|
|
2021-02-22 17:00:42 -04:00
|
|
|
- added mRoControlZeroH7 support
|
|
|
|
|
|
2021-02-06 00:43:35 -04:00
|
|
|
The main reason for this release is the parameter backup/restore. This
|
|
|
|
|
has been an ongoing issue for quite some time. The symptom is an
|
|
|
|
|
unexpected full parameter reset on boards using FRAM (also known as
|
|
|
|
|
RAMTRON) for storage, particularly those using F7 or H7 based
|
|
|
|
|
MCUs. The issue has most commonly been seen on the Hex CubeOrange
|
|
|
|
|
board, but has been seen on boards from other vendors as well.
|
|
|
|
|
|
|
|
|
|
The issue has been frustratingly difficult to reproduce. We did narrow
|
|
|
|
|
down one cause last year which was a floating CS pin in the bootloader
|
|
|
|
|
triggering corruption before ArduPilot starts. An updated bootloader
|
|
|
|
|
reduced the occurrance of the issue a lot and we thought it was
|
|
|
|
|
solved. Since then the problem has still happened a few times on
|
|
|
|
|
boards that have had a bootloader update.
|
|
|
|
|
|
|
|
|
|
This release avoids the issue by keeping a complete second copy of the
|
|
|
|
|
parameters in the 2nd half of 32k FRAM devices. On boot we check the
|
|
|
|
|
integrity of the primary parameter storage area via a simple signature
|
|
|
|
|
check and if it has been corruptted then we restore from the backup
|
|
|
|
|
area. We also raise an internal error named "params_restored". You
|
|
|
|
|
will then need to reboot to clear the error, but your parameters will
|
|
|
|
|
have been automatically recovered, avoiding the need to reload
|
|
|
|
|
parameters and re-calibrate.
|
|
|
|
|
|
|
|
|
|
If you get this internal error then it would be appreciated if you
|
|
|
|
|
could send us the contents of your APM/STRG_BAK directory on the
|
|
|
|
|
microSD card so we can analyse the corruption that happened and ensure
|
|
|
|
|
that the fix covers all real cases.

|
- Fixed UDP RC input on Linux boards to accept up to 16 RC inputs on UDP
|
|
|
|
|
|
|
|
|
|
The most critical fix in the above list is the ISR flood issue.
|
|
|
|
|
|
|
|
|
|
ISR Flood Issue
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
The ISR flood issue happens when a misbehaving external sensor (such
|
|
|
|
|
as an RPM sensor for a petrol motor) starts providing pulses faster
|
|
|
|
|
than the flight controller can process them. If this happens then the
|
|
|
|
|
CPU can be overloaded in the interrupt handling for the sensor and
|
|
|
|
|
stop flying the vehicle. The level of interrupt rate needed to cause
|
|
|
|
|
this issue is around 500k interrupts per second, so to be safe we have
|
|
|
|
|
added a limit of 100k interrupts per second. If a single interrupt
|
|
|
|
|
source produces more than 10k interrupts in a single 0.1 second period
|
|
|
|
|
then we disable that interrupt source, print a warning to the user and
|
|
|
|
|
raise an internal error.
|
|
|
|
|
|
|
|
|
|
Happy flying!

|
|
The key changes to existing behaviour to watch out for in this update
|
|
|
|
|
are:
|
|
|
|
|
|
|
|
|
|
USB IDs
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
ArduPilot has now switched to it's own USB IDs for all boards. For
|
|
|
|
|
most users this won't cause any change, except they may notice the
|
|
|
|
|
drop down list of devices in MissionPlanner will have the ArduPilot
|
|
|
|
|
flight controllers labelled more usefully as "ArduPilot" instead of
|
|
|
|
|
just "STM32". If you hit issues on windows please try reinstalling the
|
|
|
|
|
device drivers from this URL:
|
|
|
|
|
https://firmware.ardupilot.org/Tools/MissionPlanner/driver.msi
|
|
|
|
|
|
|
|
|
|
Terrain
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
A bug fix in the format ArduPilot uses to store terrain data means
|
|
|
|
|
that your flight controller will need to re-download the terrain data
|
|
|
|
|
onto the sdcard via your GCS. If you fly without a GCS and you use
|
|
|
|
|
terrain data then please re-download the terrain data you need by
|
|
|
|
|
setting up a mission when you have internet access and allowing your
|
|
|
|
|
flight controller to request terrain data from your GCS.
|
|
|
|
|
|
|
|
|
|
Pressure Altitude Compensation
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
This release adds in the missing hook for the VTOL motor controller on
|
|
|
|
|
a quadplane to compensate the VTOL gains using your pressure
|
|
|
|
|
altitude. For most people this will not have a noticible effect, but
|
|
|
|
|
some users that have tuned their aircraft for high locations may
|
|
|
|
|
notice a tuning change.
|
|
|
|
|
|
|
|
|
|
Compass Ordering
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
The new compass ordering system in this release gives a lot more
|
|
|
|
|
flexibility and should preseve existing configurations and
|
|
|
|
|
calibrations. If you hit issues then please have a look at the new
|
|
|
|
|
compass ordering user interface in recent beta releases of
|
|
|
|
|
MissionPlanner.
|
|
|
|
|
|
|
|
|
|
THR_FAILSAFE=2
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
For people flying before visual range (with appropriate
|
|
|
|
|
authorisations) there is a new option which allows for safer
|
|
|
|
|
operation. By setting THR_FAILSAFE=2 you can setup the R/C failsafe so
|
|
|
|
|
that R/C input will stop being used when one of the receiver failsafe
|
|
|
|
|
conditions is met, while not triggering any failsafe actions. This is
|
|
|
|
|
a significant improvement over setting THR_FAILSAFE=0 as it prevents
|
|
|
|
|
the receiver inputs being used for stick mixing and other inputs that
|
|
|
|
|
would be inappropriate when in receiver failsafe.
|
|
|
|
|
|
|
|
|
|
Many thanks to everyone who contributed to and tested this release!

Happy flying!

The key changes to existing behaviour to watch out for in this update
|
|
|
|
|
are:
|
|
|
|
|
|
|
|
|
|
USB IDs
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
ArduPilot has now switched to it's own USB IDs for all boards. For
|
|
|
|
|
most users this won't cause any change, except they may notice the
|
|
|
|
|
drop down list of devices in MissionPlanner will have the ArduPilot
|
|
|
|
|
flight controllers labelled more usefully as "ArduPilot" instead of
|
|
|
|
|
just "STM32". If you hit issues on windows please try reinstalling the
|
|
|
|
|
device drivers from this URL:
|
|
|
|
|
https://firmware.ardupilot.org/Tools/MissionPlanner/driver.msi
|
|
|
|
|
|
|
|
|
|
Terrain
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
A bug fix in the format ArduPilot uses to store terrain data means
|
|
|
|
|
that your flight controller will need to re-download the terrain data
|
|
|
|
|
onto the sdcard via your GCS. If you fly without a GCS and you use
|
|
|
|
|
terrain data then please re-download the terrain data you need by
|
|
|
|
|
setting up a mission when you have internet access and allowing your
|
|
|
|
|
flight controller to request terrain data from your GCS.
|
|
|
|
|
|
|
|
|
|
Pressure Altitude Compensation
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
This release adds in the missing hook for the VTOL motor controller on
|
|
|
|
|
a quadplane to compensate the VTOL gains using your pressure
|
|
|
|
|
altitude. For most people this will not have a noticible effect, but
|
|
|
|
|
some users that have tuned their aircraft for high locations may
|
|
|
|
|
notice a tuning change.
|
|
|
|
|
|
|
|
|
|
Compass Ordering
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
The new compass ordering system in this release gives a lot more
|
|
|
|
|
flexibility and should preseve existing configurations and
|
|
|
|
|
calibrations. If you hit issues then please have a look at the new
|
|
|
|
|
compass ordering user interface in recent beta releases of
|
|
|
|
|
MissionPlanner.

|

Many thanks to everyone who contributed to and tested this release!

|
|
|
|
|
|
|
|
This release includes a significant number of changes from 4.0.3. Key
|
|
|
|
|
changes are:
|
|
|
|
|
|
|
|
|
|
- re-sync the 4.0 release with Copter-4.0, bringing them in line so
|
|
|
|
|
as to maximise cross-vehicle testing
|
|
|
|
|
|
|
|
|
|
- fixed a timing issue in IOMCU that could lead to loss of RC input
|
|
|
|
|
frames and increased latency of output to ESCs on the IOMCU
|
|
|
|
|
|
|
|
|
|
- fixed a bug in restoring gains in QAUTOTUNE that could cause the
|
|
|
|
|
aircraft to be unstable on leaving QAUTOTUNE mode
|
|
|
|
|
|
2020-02-16 02:02:34 -04:00
|
|
|
- fixed stack size of ftp thread
|
|
|
|
|
|
2020-02-04 21:15:52 -04:00
|
|
|
The Copter-4.0 re-sync brings in quite a few structural changes. The
|
|
|
|
|
main user visible changes are:
|
|
|
|
|
|
|
|
|
|
- UAVCAN DNA server no longer needs a microSD card to operate
|
|
|
|
|
|
|
|
|
|
- added logging of UAVCAN servos and ESC feedback messages
|
|
|
|
|
|
|
|
|
|
- reduced QTUN logging rate to 25Hz
|
|
|
|
|
|
|
|
|
|
- reduced memory usage in EKF with multiple lanes
|
|
|
|
|
|
|
|
|
|
- Minor OSD improvements
|
|
|
|
|
|
|
|
|
|
- added a lot more scripting bindings
|
|
|
|
|
|
|
|
|
|
- fixed UAVCAN GPS status when not connected
|
|
|
|
|
|
|
|
|
|
- added EK3_MAG_EF_LIM limit for earth frame mag errors

|
|
|
|
|
particularly appreciate as much flight testing as we can get on this
|
|
|
|
|
release.

Release 4.0.3, 21st January 2020
|
|
|
|
|
--------------------------------
|
2020-01-18 05:32:57 -04:00
|
|
|
|
|
|
|
|
This is a minor release with a few bug fixes and enhancements. The
|
|
|
|
|
changes since beta1 are:
|
|
|
|
|
|
|
|
|
|
- fixed 3 missing semaphore waits
|
|
|
|
|
- fixed checking for bouncebuffer allocation on microSD card IO
|
|
|
|
|
- fixed incorrect param count
|
2020-01-10 04:08:39 -04:00
|
|
|
- prevent failsafe action from overriding a VTOL land
|
|
|
|
|
- fixed compass calibration failures with auto-rotation detection
|
|
|
|
|
- fixed errors on STM32H7 I2C (affects CubeOrange and Durandal)
|
|
|
|
|
- fixed a race condition in FrSky passthrough telemetry
|
|
|
|
|
- fixed DSM/Spektrum parsing for 22ms protocols
|
|
|
|
|
- added fixed yaw compass calibration method
|
|
|
|
|
- re-generated magnetic field tables
|
|
|
|
|
- ensure SERIAL0_PROTOCOL is mavlink on boot
|
|
|
|
|
|
|
|
|
|
The most important fix is for FrSky pass-through telemetry. Pass
|
|
|
|
|
through telemetry support had a race condition which could lead to the
|
|
|
|
|
flight controller generating a fault and rebooting. Until you are
|
|
|
|
|
running a firmware with the fix you should disable FrSky pass-through
|
|
|
|
|
telemetry by changing SERIALn_PROTOCOL from 10 to 0 on the where you
|
|
|
|
|
have SPort enabled.

Release 3.9.8, 26th April 2019
|
|
|
|
|
------------------------------
|
2019-04-22 04:08:03 -03:00
|
|
|
|
|
|
|
|
This is a minor release with some important safety fixes. The fixes
|
|
|
|
|
relate to two issues:
|
|
|
|
|
|
|
|
|
|
- implement hardware support to reset the CPU if a software or hardware
|
|
|
|
|
failure causes the main loop to stop running
|
|
|
|
|
|
|
|
|
|
- fixed a bug in the handling of a failure of the primary IMU in a
|
|
|
|
|
multi-IMU system
|
|
|
|
|
|
|
|
|
|
The first fix relates to a flyaway that happened on a RadioLink
|
|
|
|
|
mini-pix flight controller. The mini-pix suffered a major hardware
|
|
|
|
|
failure that led to the main loop stopping. As the mini-pix does not
|
|
|
|
|
have an IO co-processor this resulted in fixed control surface outputs
|
|
|
|
|
and fixed motor output, which led to a flyaway. The plane was found,
|
|
|
|
|
but we want to ensure that if this ever happens again that the motor
|
|
|
|
|
will stop and that the pilot will regain control of the aircraft.
|
|
|
|
|
|
|
|
|
|
The fix is to enable an option in the STM32 processor called
|
|
|
|
|
"Independent Watchdog" (IWDG). The IWDG provides a mechanism to
|
|
|
|
|
automatically reset the CPU on software or hardware failure resulting
|
|
|
|
|
in the main loop stopping. When this happens the hardware also
|
|
|
|
|
provides a mechanism for ArduPilot to know that it is booting after a
|
|
|
|
|
watchdog reset, in which case it does the following:
|
|
|
|
|
|
|
|
|
|
- if the ChibiOS bootloader has been updated then it skips the normal
|
|
|
|
|
5 second delay in the bootloader
|
|
|
|
|
|
|
|
|
|
- it skips baromoter, gyro and airspeed calibration, allowing for
|
|
|
|
|
very fast boot
|
|
|
|
|
|
|
|
|
|
- the home position and attitude estimate of the vehicle is restored
|
|
|
|
|
to a point less than 0.3 seconds before the lockup
|
|
|
|
|
|
|
|
|
|
- the pilot regains full control, and if the pilot requests arming
|
|
|
|
|
then arming checks are automatically bypassed
|
|
|
|
|
|
|
|
|
|
We have tested this on an aircraft with a deliberately induced full
|
|
|
|
|
CPU lockup. The aircraft recovered and flew normally within 3 seconds
|
|
|
|
|
of lockup, with the pilot having full control. This was with a board
|
|
|
|
|
with no IOMCU. A board that does have an IOMCU (such as a Hex cube)
|
|
|
|
|
would have had full manual control on FMU lockup without the changes
|
|
|
|
|
in this new release. For those boards with IOMCU the advantage of the
|
|
|
|
|
new release is that the pilot will regain the ability to use
|
|
|
|
|
stabilised and auto modes (including RTL) after a full CPU lockup.
|
|
|
|
|
|
|
|
|
|
The additional protections of the IWDG support only apply to the
|
|
|
|
|
ChibiOS builds. The IWDG is not supported in NuttX builds.
|
|
|
|
|
|
|
|
|
|
The second key fix in this release relates to IMU failure on multi-IMU
|
|
|
|
|
systems. If the IMU that is associated with the currently active EKF
|
|
|
|
|
lane failed then the fixed wing attitude controller would lose
|
|
|
|
|
attitude control and the aircraft will crash unless the pilot takes
|
|
|
|
|
manual control. This has been fixed to ensure that IMU failover
|
|
|
|
|
operates correctly.
|
|
|
|
|
|
|
|
|
|
Other changes in this release:
|
|
|
|
|
|
|
|
|
|
- added support for the CUAVv5Nano board
|
|
|
|
|
|
|
|
|
|
- added retries to flash storage of parameters
|
|
|
|
|
|
|
|
|
|
- fixed pullups on some fmuv3 based boards that lack hardware pullups
|
|
|
|
|
on sdcard data lines
|
|
|
|
|
|
|
|
|
|
- fixed fallback to microSD for parameter storage if a board with
|
|
|
|
|
FRAM storage has a failed FRAM device
|
|
|
|
|
|
2019-04-25 18:15:07 -03:00
|
|
|
- added a specific check for hw failure regarding the recent
|
|
|
|
|
CubeBlack safety bulletin
|
|
|
|
|
|
|
|
|
|
- fixed the power flags for brick2 on fmuv5

Release 3.9.7, 1st April 2019
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
This is a minor release to fix a single important bug in speed/height
|
|
|
|
|
handling. The bug was in the TECS (total energy control system) and
|
|
|
|
|
could cause a sustained pitch down due to a transient glitch in
|
|
|
|
|
airspeed demand resulting in a large negative pitch integrator.
|
|
|
|
|
|
|
|
|
|
The log that found the bug was of a quadplane in CRUISE mode, and
|
|
|
|
|
resulted in the aircraft forcing nose down for long enough to crash.
|
|
|
|
|
|
|
|
|
|
The fix includes both protections for the pitch integrator and a fix
|
|
|
|
|
for the cause of the transient in airspeed demand affecting the TECS
|
|
|
|
|
demanded airspeed.
|
|

|
|
|
|
|
|
|
|
|
|
This is a minor release with some important fixes for VTOL landings
|
|
|
|
|
and EKF handling of compass switching.
|
|
|

|
|
|
|

|
|
update over 3.9.0. This release includes the following changes:

|
|

|
|
|

|
|
|
|
|
|
|
|
|
|
- updated OSD with new items: hdop, temperature, waypoint, xtrack,
|
|
|
|
|
flight distance, flighttime, efficiency (thanks to Hwurzburg,
|
|
|
|
|
vierfuffzig and sh83).
|
|
|
|
|
|
|
|
|
|
- reduced memory usage in serial buffers
|
|
|
|
|
|
|
|
|
|
- adjusted some default parameters to give a better first flight
|
|
|
|
|
experience for more users.
|
|
|
|
|
|
|
|
|
|
The default parameter changes are:
|
|
|
|
|
|
|
|
|
|
- RLL2SRV_P from 0.6 to 1.0
|
|
|
|
|
- RLL2SRV_I from 0.1 to 0.3
|
|
|
|
|
- RLL2SRV_D from 0.02 to 0.08
|
|
|
|
|
- PTCH2SRV_P from 0.6 to 1.0
|
|
|
|
|
- PTCH2SRV_I from 0.1 to 0.3
|
|
|
|
|
- PTCH2SRV_D from 0.02 to 0.08
|
|
|
|
|
- TECS_PITCH_MAX from 0 to 15
|
|
|
|
|
- NAVL1_PERIOD from 20 to 17
|
|
|
|
|
|
|
|
|
|
The PID parameter changes won't affect anyone who has done some
|
|
|
|
|
tuning, but will make the first flight experience for a new user be a
|
|
|
|
|
lot better for nearly all aircraft. Paul and I decided on the values
|
|
|
|
|
based on experience with users flight logs, plus the experience users
|
|
|
|
|
have had with AUTOTUNE mode.
|
|
|
|
|
|
|
|
|
|
Please report testing results!

Release 3.9.0, 6th August 2018
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
The ArduPilot development team is delighted to announce a new stable
|
|
|
|
|
release of plane, version 3.9.0.
|
|
|
|
|
|
|
|
|
|
For those of you who have been testing the 3.9.0beta releases then you
|
|
|
|
|
won't see any surprises here. That are no changes since
|
|
|
|
|
3.9.0beta6. Also, many thanks for testing the betas!
|
|
|
|
|
|
|
|
|
|
For those of you coming from the last stable 3.8.5 release there are a
|
|
|
|
|
lot of changes. For a start, this is the first release to support both
|
|
|
|
|
the ChibiOS RTOS on STM32 boards and the NuttX RTOS. Previously stable
|
|
|
|
|
releases only used the NuttX RTOS. The ArduPilot project is moving to
|
|
|
|
|
ChibiOS for future releases, and we expect to drop support for the
|
|
|
|
|
NuttX builds for the next major stable release (which will probably be
|
|
|
|
|
called 3.10.0).
|
|
|
|
|
|
|
|
|
|
When you install the 3.9.0 release on board such as a Pixhawk1, Cube
|
|
|
|
|
or Pixracer you have a choice of which build to use. Choosing ChibiOS
|
|
|
|
|
will give you better performance and some very nice new
|
|
|
|
|
features. Choosing the NuttX (also known as "PX4" builds) will get you
|
|
|
|
|
the same base that we have been using for years.
|
|
|
|
|
|
|
|
|
|
There are a few features that are in the NuttX build but not yet in
|
|
|
|
|
the ChibiOS build, in particular the ChibiOS build does not yet
|
|
|
|
|
support PWM based rangefinders. That will be fixed in a future
|
|
|
|
|
release.
|
|
|
|
|
|
|
|
|
|
This release has a lot of new features. Some of the most important
|
|
|
|
|
ones are:
|
|
|
|
|
|
|
|
|
|
- DShot support for controlling ESCs
|
|
|
|
|
- BLHeli pass-thru support for ESC configuration
|
|
|
|
|
- automatic compass orientation on calibrating compasses
|
|
|
|
|
- improved VTOL flight code, with improved transition support and loiter
|
|
|
|
|
- support for Devo telemetry output
|
|
|
|
|
- new battery monitoring system, with more flexible failsafes
|
|
|
|
|
- built-in OSD support for boards with a MAX7456 OSD device
|
|
|
|
|
|
|
|
|
|
In addition, this release supports a lot of new flight boards,
|
|
|
|
|
including:
|
|
|
|
|
|
|
|
|
|
- AirbotF4
|
|
|
|
|
- F4BY
|
|
|
|
|
- KakuteF4
|
|
|
|
|
- KakuteF7
|
|
|
|
|
- MatekF405
|
|
|
|
|
- MatekF405-Wing
|
|
|
|
|
- mindpx-v2
|
|
|
|
|
- mini-pix
|
|
|
|
|
- Omnibusf4pro
|
|
|
|
|
- Omnibusf7V2
|
|
|
|
|
- Pixhawk4 and Pixhawk4-mini
|
|
|
|
|
- CUAVv5
|
|
|
|
|
- revo and revo-mini
|
|
|
|
|
- sparky2
|
|
|
|
|
|
|
|
|
|
We also now have custom ChibiOS based builds for some existing boards,
|
|
|
|
|
including:
|
|
|
|
|
|
|
|
|
|
- CubeBlack
|
|
|
|
|
- mRoX21
|
|
|
|
|
- Pixhawk1
|
|
|
|
|
- Pixracer
|
|
|
|
|
|
|
|
|
|
This means you now have a lot more choice in selecting a flight board
|
|
|
|
|
to use with ArduPilot.
|
|
|
|
|
|
|
|
|
|
This release was made possible thanks to contributions from dozens of
|
|
|
|
|
volunteer developers in the dev team. In total there are over 5
|
|
|
|
|
thousand changes since the 3.8.5 release. Special thanks to:

Release 3.9.0beta1, 21st May 2018
|
|
|
|
|
---------------------------------
|
|
|
|
|
|
|
|
|
|
This is the first in a series of beta releases for plane 3.9.0. It is
|
|
|
|
|
a major release, with a lot of changes.
|
|
|
|
|
|
|
|
|
|
The main changes are for supporting two new HALs (hardware abstraction
|
|
|
|
|
layers). One is the port to ChibiOS and the second is the F4Light HAL.
|
|
|
|
|
|
|
|
|
|
These ports bring a host of new flight board options, and a lot of new
|
|
|
|
|
features. Some highlights include:
|
|
|
|
|
|
|
|
|
|
- support for many inexpensive STM32F4 based flight boards
|
|
|
|
|
|
|
|
|
|
- support for DShot output for BLHeli ESCs, including ESC telemetry
|
|
|
|
|
feedback
|
|
|
|
|
|
|
|
|
|
- new battery monitoring system with more flexible failsafe options
|
|
|
|
|
|
|
|
|
|
- support for Devo telemetry output
|
|
|
|
|
|
|
|
|
|
- a new position hold library for multicopters which improves
|
|
|
|
|
quadplane VTOL support
|
|
|
|
|
|
|
|
|
|
This release is fully compatible with previous releases, and users
|
|
|
|
|
should not notice a significant difference in flight. The focus of the
|
|
|
|
|
beta testing will be on ensuring that the new flight board support is
|
|
|
|
|
stable.
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.8.5, 25th April 2018
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
This release includes small bug fixes and one safety fix. The changes
|
|
|
|
|
are:
|
|
|
|
|
|
|
|
|
|
- fixed an issue where the external safety button can activate in
|
|
|
|
|
flight on some boards, causing them to crash. A new parameter
|
|
|
|
|
BRD_SAFETYOPTION is added which controls the behaviour of the
|
|
|
|
|
safety button. The default is to de-activate the safety button when
|
|
|
|
|
armed.
|
|
|
|
|
|
|
|
|
|
- fixed default orientation of ICM-20948 compass for Here GPS
|
|
|
|
|
|
|
|
|
|
- added support for dual airspeed sensors
|
|
|
|
|
|
|
|
|
|
- added support for the SDP33 airspeed sensor. This is still
|
|
|
|
|
considered experimental. There are reports of it underestimating
|
|
|
|
|
the aircrafts speed at higher altitudes.
|
|
|
|
|
|
|
|
|
|
- add support for the MS5525 airspeed sensor on multiple I2C
|
|
|
|
|
addresses. Two new values of the ARSDP_TYPE are introduced (4 and
|
|
|
|
|
5) for specific I2C addresses. This allows you to deconflict the
|
|
|
|
|
MS5525 from a MS5611 barometer on the same bus.

Release 3.8.4, 9th January 2018
|
|
|
|
|
-------------------------------
|
|
|
|
|
|
|
|
|
|
This is a minor release with just two small changes.
|
|
|
|
|
|
|
|
|
|
The first change is to fix a timing bug in the MS5525 airspeed sensor
|
|
|
|
|
driver. That bug was causing unreliable airspeed sensing. Thanks to
|
|
|
|
|
David Ingraham for providing logs that helped find the issue.
|
|
|
|
|
|
|
|
|
|
The second change is to fix transitions in AUTO mode in
|
|
|
|
|
tailsitter. The transition for tailsitters was causing instability on
|
|
|
|
|
transition from vertical takeoff to forward flight.
|
|
|
|
|
|
|
|
|
|
|
2017-11-13 00:06:42 -04:00
|
|
|
Release 3.8.3, 13th November 2017
|
|
|
|
|
---------------------------------
|
2017-10-30 04:46:51 -03:00
|
|
|
|
|
|
|
|
This is a minor release with a number of important bug fixes and some
|
|
|
|
|
small feature additions.
|
|
|
|
|
|
2017-11-13 00:06:42 -04:00
|
|
|
The most important general fixes are for an I2C device detection bug
|
|
|
|
|
and fixing the implementation of MANUAL_RCMASK.
|
|
|
|
|
|
|
|
|
|
There are quite a number of small fixes in lots of areas, plus big
|
|
|
|
|
improvements to the handling of tailsitter transitions.
|
|
|
|
|
|
|
|
|
|
Another significant change is to the handling of transitions from RTL
|
|
|
|
|
to QRTL when Q_RTL_MODE=1. We now transition to QRTL at a distance
|
|
|
|
|
which is the maximum of RTL_RADIUS and a distance calculated based on
|
|
|
|
|
a new Q_TRANS_DECEL "transition deceleration" parameter. That allows
|
|
|
|
|
you to tune the amount of deceleration you want in the transition
|
|
|
|
|
according to how much drag your quadplane has. This also means it
|
|
|
|
|
automatically accounts for wind speed and approach speed in
|
|
|
|
|
calculating the transition point.
|
|
|
|
|
|
|
|
|
|
We have also added a new Q_OPTIONS parameter which is a bitmask of
|
|
|
|
|
option flags to control quadplane behaviour. We have three options so
|
|
|
|
|
far. The first is to allow for keeping the wings within
|
|
|
|
|
LEVEL_ROLL_LIMIT degrees during transitions, for users that prefer
|
|
|
|
|
transitions to be kept level. The 2nd and 3rd options are to treat
|
|
|
|
|
NAV_TAKEOFF as NAV_VTOL_TAKEOFF and NAV_LAND as NAV_VTOL_LAND in
|
|
|
|
|
quadplane missions, so that you can use GCS software that doesn't know
|
|
|
|
|
about the VTOL takeoff and land commands.
|
|
|
|
|
|
2017-10-30 04:46:51 -03:00
|
|
|
- allow vertical takeoffs in GUIDED mode with Q_GUIDED_MODE=0
|
|
|
|
|
|
|
|
|
|
- fixed a bug in implementation of MANUAL_RCMASK
|
|
|
|
|
|
|
|
|
|
- eliminate airspeed positive bias after offset zero
|
|
|
|
|
|
|
|
|
|
- prevent quadplane controller windup on the ground
|
|
|
|
|
|
|
|
|
|
- added Q_MAV_TYPE for setup of VTOL vehicle type for QGC
|
|
|
|
|
|
|
|
|
|
- improved performance of FlightAxis SITL
|
|
|
|
|
|
|
|
|
|
- support LOITER_TO_ALT in quadplanes
|
|
|
|
|
|
|
|
|
|
- fixed a bug in TECS related to descending quadplane transitions
|
|
|
|
|
|
|
|
|
|
- added Q_OPTIONS for controlling roll during transitions and
|
|
|
|
|
allowing for fixed wing takeoff and landing
|
|
|
|
|
|
|
|
|
|
- fixed a race condition in IMU logging
|
|
|
|
|
|
|
|
|
|
- fixed a race in i2c device probing
|
|
|
|
|
|
|
|
|
|

|
|
|
|
|
- added IST8310 compass on FMUv3 I2C
|
|
|
|
|
|
|
|
|
|
- probe for QMC5883 by default
|
|
|
|
|
|
|
|
|
|
- avoid double detection of AK09916 compass
|
|
|
|
|
|
|
|
|
|
- smooth out tailsitter transitions in both directions
|
|
|
|
|
|
2017-11-05 06:47:15 -04:00
|
|

Release 3.8.2, 11th September 2017
|
|
|
|
|
----------------------------------
|
2017-09-08 19:28:01 -03:00
|
|
|
|
|
|
|
|
This is a minor release, with a few small fixes and one important
|
|
|
|
|
crash bug fix.
|
|
|
|
|
|
|
|
|
|
The crash bug is in the Septentrio (SBF) GPS driver. Anyone flying
|
|
|
|
|
with an SBF GPS should update to this release. The driver had a bug
|
|
|
|
|
that could cause a in-flight crash under some circumstances.
|
|
|
|
|
|
|
|
|
|
Other changes in this release are:
|
|
|
|
|
|
|
|
|
|
- support takeoff in GUIDED mode for quadplanes
|
|
|
|
|
|
|
|
|
|
- support changing target altitude while hovering in GUIDED mode for
|
|
|
|
|
quadplanes
|
|
|
|
|
|
|
|
|
|
- improved descent rate control in QRTL and QLAND modes. This fixes
|
|
|
|
|
an issue with higher than configured descent rates, and smoothes
|
|
|
|
|
out the change in descent rate for the change to the final landing
|
|
|
|
|
stage
|
|
|
|
|
|
|
|
|
|
- smooth out the transition to QLOITER or QLAND when transitioning
|
|
|
|
|
from fixed wing mode. This prevents the sudden nose up when
|
|
|
|
|
changing to QLOITER or QLAND mode while flying at high speed.
|
|
|
|
|
|
2017-09-10 20:55:41 -03:00
|
|
|
- added MANUAL_CONTROL support, allowing for joystick control from QGroundControl
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.8.1, 3rd September 2017
|
|
|
|
|
---------------------------------
|
|
|
|
|
|
|
|
|
|
This is a bugfix release for 3.8.0, with just a few small changes, and
|
|
|
|
|
only one new feature.
|
|
|
|
|
|
|
|
|
|
The bug fixes are:
|
|
|
|
|
|
|
|
|
|
- removed TRIM_RC_AT_START option, as this was causing significant
|
|
|
|
|
issues
|
|
|
|
|
|
|
|
|
|
- fixed bug in TRIM_AUTO support with differential spoilers
|
|
|
|
|
|
|
|
|
|
- fixed bug with RCn_TRIM == RCn_MIN in MANUAL mode
|
|
|
|
|
|
|
|
|
|
- fixed combination of TKOFF_THR_MINACC and TKOFF_THR_DELAY
|
|
|
|
|
|
|
|
|
|
- fixed a bug in sending STATUSTEXT messages on all MAVLink channels
|
|
|
|
|
|
|
|
|
|
The new feature is that you can set the protocol for the debug UART on
|
|
|
|
|
FMUv2 or FMUv3 board (such as a Pixhawk or Cube) to allow allow UART5
|
|
|
|
|
to be used for arbitrary protocols. To use this fetaure just set
|
|
|
|
|
SERIAL5_PROTOCOL to the desired serial protocol. This should be useful
|
|
|
|
|
to users who have multiple serial devices (such as rangefinders) they
|
|
|
|
|
want to connect and have run out of UARTs.
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.8.0, 5th August 2017
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
The ArduPilot development team is very proud to announce the release
|
|
|
|
|
of APM:Plane 3.8.0. This is a major release, with a lot of new
|
|
|
|
|
features and improvements. The release has been a long time coming,
|
|
|
|
|
and the dev team would like to thank everyone who has contributed,
|
|
|
|
|
in terms of code and documentation as well as the many testers of beta
|
|
|
|
|
versions of the code.
|
|
|
|
|
|
|
|
|
|
To help with migration from the 3.7.1 release to 3.8.0 there is a
|
|
|
|
|
migration guide here:
|
|
|
|
|
|
|
|
|
|
http://ardupilot.org/plane/docs/plane-3-7-to-3-8-migration.html
|
|
|
|
|
|
|
|
|
|
All users should read the migration guide carefully. While the
|
|
|
|
|
firmware will try to auto-migrate most settings, please do very
|
|
|
|
|
careful ground tests before your first flight with 3.8.
|
|
|
|
|
|
|
|
|
|
In total there have been over 4 thousand changes in the ArduPilot git
|
|
|
|
|
tree since the 3.7.1 release, with over four hundred of those specific
|
|
|
|
|
to fixed wing aircraft. Listing all of them in these release notes is
|
|

|
|
|
|
|
version 3.8.0beta of APM:Plane. This is a major release. All users
|
|
|
|
|
should carefully check their setup when upgrading.
|
|
|
|
|
|
|
|
|
|
Major changes include:
|
|
|
|
|
|
|
|
|
|
- new SRV_Channel system for setting up of output servos separately
|
|
|
|
|
from input RC channels
|
2017-05-01 07:30:32 -03:00
|
|
|
- new elevon and vtail support system
|
2017-04-04 07:49:10 -03:00
|
|
|
- new EKF3 state estimator (not enabled by default yet)
|
|
|
|
|

|
|
|
|
|
- greatly improved support for tilt-rotor quadplanes
|
|
|
|
|
- greatly improved quadplane transition code
|
|
|
|
|
- support for deepstall landing
|
|
|
|
|
- large improvements in airspeed noise handling
|
|
|
|
|
- much improved RTK GPS support
|
|
|
|
|
- support automatic servo trimming
|
|
|
|
|
- greatly improved automatic landing accuracy
|
|
|
|
|
- significant improvements in altitude handling
|
2017-05-01 07:30:32 -03:00
|
|
|
- significant improvement in sensor drivers, with higher sample rates
|
|
|
|
|
and improved vibration resistance
|
2017-04-04 07:49:10 -03:00
|
|
|
|
|
|
|
|
On top of that there have been hundreds of smaller improvements and
|
|
|
|
|
bug fixes.
|
|
|
|
|
|
|
|
|
|
From the users point of view the most significant change in setup is
|
|
|
|
|
moving of RCn_FUNCTION parameters into new SERVOn_FUNCTION parameters,
|
|
|
|
|
and the creation of separate output MIN/MAX/TRIM values for all servo
|
|
|
|
|
outputs. This allows for much more flxible output setup that is
|
|
|
|
|
independent of RC input setup.

Release 3.7.0, 9th September 2016
|
|
|
|
|
---------------------------------
|
2016-09-02 03:52:24 -03:00
|
|
|
|
|
|
|
|
The ArduPilot development team is proud to announce the release of
|
|
|
|
|
version 3.7.0 of APM:Plane. This is a major update so please read the
|
|
|
|
|
notes carefully.
|
|
|
|
|
|
|
|
|
|
The biggest changes in this release are:
|
|
|
|
|
|
|
|
|
|
- more reliable recovery from inverted flight
|
|
|
|
|
- automatic IC engine support
|
|
|
|
|
- Q_ASSIST_ANGLE for stall recovery on quadplanes
|
|
|
|
|
- Pixhawk2 IMU heater support
|
|
|
|
|
- PH2SLIM support
|
|
|
|
|
- AP_Module support
|
|
|
|
|
- Parrot Disco support
|
|
|
|
|
- major VRBrain support merge
|
|
|
|
|
- much faster boot time on Pixhawk
|
|
|
|
|
|
|
|
|
|
I'll give a bit of detail on each of these changes before giving the
|
|
|
|
|
more detailed list of changes.
|
|
|
|
|
|
|
|
|
|
More reliable recovery from inverted flight
|
|
|
|
|
|
|
|
|
|
Marc Merlin discovered that on some types of gliders that ArduPilot
|
|
|
|
|
would not reliably recover from inverted flight. The problem turned
|
|
|
|
|
out to be the use of the elevator at high bank angles preventing the
|
|
|
|
|
ailerons from fully recovering attitude. The fix in this release
|
|
|
|
|
prevent excessive elevator use when the aircraft is beyond
|
|
|
|
|
LIM_ROLL_CD. This should help a lot for people using ArduPilot as a
|
|
|
|
|
recovery system for manual FPV flight.
|
|
|
|
|
|
|
|
|
|
Automatic IC engine support
|
|
|
|
|
|
|
|
|
|
ArduPilot has supported internal combustion engines for a long time,
|
|
|
|
|
but until now the pilot has had to control the ignition and starter
|
|
|
|
|
manually using transmitter pass throughs. A new "ICE" module in
|
|
|
|
|
ArduPilot now allows for fully automatic internal combustion engine
|
|
|
|
|
support.
|
|
|
|
|
|
|
|
|
|
Coupled with an RPM sensor you can setup your aircraft to
|
|
|
|
|
automatically control the ignition and starter motor, allowing for one
|
|
|
|
|
touch start of the motor on the ground and automatic restart of the
|
|
|
|
|
motor in flight if needed.
|
|
|
|
|
|
|
|
|
|
The IC engine support is also integrated into the quadplane code,
|
|
|
|
|
allowing for automatic engine start at a specified altitude above the
|
|
|
|
|
ground. This is useful for tractor engine quadplanes where the
|
|
|
|
|
propeller could strike the ground on takeoff. The engine can also be
|
|
|
|
|
automatically stopped in the final stage of a quadplane landing.
|
|
|
|
|
|
|
|
|
|
Q_ASSIST_ANGLE for stall recovery
|
|
|
|
|
|
|
|
|
|
Another new quadplane feature is automatic recovery from fixed wing
|
|
|
|
|
stall. Previously the VTOL motors would only provide assistance in
|
|
|
|
|
fixed wing modes when the aircraft airspeed dropped below
|
|
|
|
|
Q_ASSIST_SPEED. Some stalls can occur with higher airspeed however,
|
|
|
|
|
and this can result in the aircraft losing attitude control without
|
|
|
|
|
triggering a Q_ASSIST_SPEED recovery. A new parameter Q_ASSIST_ANGLE
|
|
|
|
|
allows for automatic assistance when attitude control is lost,
|
|
|
|
|
triggering when the attitude goes outside the defined roll and pitch
|
|
|
|
|
limits and is more than Q_ASSIST_ANGLE degrees from the desired
|
|
|
|
|
attitude. Many thanks to Iskess for the suggestion and good discussion
|
|
|
|
|
around this feature.
|
|
|
|
|
|
|
|
|
|
Pixhawk2 heated IMU support
|
|
|
|
|
|
|
|
|
|
This release adds support for the IMU heater in the upcoming Pixhawk2,
|
|
|
|
|
allowing for more stable IMU temperatures. The Pixhawk2 is
|
|
|
|
|
automatically detected and the heater enabled at boot, with the target
|
|
|
|
|
IMU temperature controllable via BRD_IMU_TARGTEMP.
|
|
|
|
|
|
|
|
|
|
Using an IMU heater should improve IMU stability in environments with
|
|
|
|
|
significant temperature changes.
|
|
|
|
|
|
|
|
|
|
PH2SLIM Support
|
|
|
|
|
|
|
|
|
|
This release adds support for the PH2SLIM variant of the Pixhawk2,
|
|
|
|
|
which is a Pixhawk2 cube without the isolated sensor top board. This
|
|
|
|
|
makes for a very compact autopilot for small aircraft. To enable
|
|
|
|
|
PH2SLIM support set the BRD_TYPE parameter to 6 using a GCS connected
|
|
|
|
|
on USB.
|
|
|
|
|
|
|
|
|
|
AP_Module Support
|
|
|
|
|
|
|
|
|
|
This is the first release of ArduPilot with loadable module support
|
|
|
|
|
for Linux based boards. The AP_Module system allows for externally
|
|
|
|
|
compiled modules to access sensor data from ArduPilot controlled
|
|
|
|
|
sensors. The initial AP_Module support is aimed at vendors integrating
|
|
|
|
|
high-rate digital image stabilisation using IMU data, but it is
|
|
|
|
|
expected this will be expanded to other use cases in future releases.
|
|
|
|
|
|
|
|
|
|
Parrot Disco Support
|
|
|
|
|
|
|
|
|
|
This release adds support for the Parrot C.H.U.C.K autopilot in the
|
|
|
|
|
new Disco airframe. The Disco is a very lightweight flying wing with
|
|
|
|
|
a nicely integrated Linux based autopilot. The Disco flies very nicely
|
|
|
|
|
with ArduPilot, bringing the full set of mission capabilities of
|
|
|
|
|
ArduPilot to this airframe.
|
|
|
|
|
|
|
|
|
|
Major VRBrain Support Update
|
|
|
|
|
|
|
|
|
|
This release includes a major merge of support for the VRBrain family
|
|
|
|
|
of autopilots. Many thanks to the great work by Luke Mike in putting
|
|
|
|
|
together this merge!
|
|
|
|
|
|
|
|
|
|
Much Faster Boot Time
|
|
|
|
|
|
|
|
|
|
Boot times on Pixhawk are now much faster due to a restructuring of
|
|
|
|
|
the driver startup code, with slow starting drivers not started unless
|
|
|
|
|
they are enabled with the appropriate parameters. The restructuring
|
|
|
|
|
also allows for support of a wide variety of board types, including
|
|
|
|
|
the PH2SLIM above.
|
|
|
|
|
|
|
|
|
|
This release includes many other updates right across the flight
|
|
|
|
|
stack, including several new features. Some of the changes include:
|
|
|
|
|
|
|
|
|
|
- improved quadplane auto-landing
|
|
|
|
|
- limit roll and pitch by Q_ANGLE_MAX in Q modes
|
|
|
|
|
- improved ADSB avoidance and MAVLink streaming
|
|
|
|
|
- smoother throttle control on fixed-wing to VTOL transition
|
|
|
|
|
- removed "demo servos" movement on boot
|
|
|
|
|
- fixed a problem with spurious throttle output during boot (thanks
|
|
|
|
|
to Marco for finding this)
|
|
|
|
|
- support MAVLink SET_ATTITUDE_TARGET message
|
|
|
|
|
- log all rally points on startup
|
|
|
|
|
- fixed use of stick mixing for rudder with STICK_MIXING=0
|
|
|
|

Release 3.5.3, 30th April 2016
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
The ArduPilot development team is proud to announce the release of
|
|
|
|
|
version 3.5.3 of APM:Plane. This is a minor release with only small
|
|
|
|
|
bugfix changes.
|
|
|
|
|
|
|
|
|
|
The main motivation for the release is a problem with flying without a
|
|
|
|
|
compass enabled. If you fly 3.5.2 with MAG_ENABLE=0 or no compass
|
|
|
|
|
attached then there is a risk that the EKF2 attitude estimator may
|
|
|
|
|
become unstable before takeoff. This can cause the aircraft to crash.
|
|
|
|
|
|
|
|
|
|
The other changes in this release are:
|
|
|
|
|
|
|
|
|
|
- fixed loiter radius for counter-clockwise loiter
|
|
|
|
|
- fixed the loiter radius when doing a RTL at the end of a mission
|
|
|
|
|
- provide reasons to the GCS when a uBlox GPS fails to properly configure
|
|
|
|
|
- support a wider variety of NMEA GPS receivers
|
|
|
|
|
- use EKF1 by default if no compass is enabled
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.5.2, 26th March 2016
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
The ArduPilot development team is proud to announce the release of
|
|
|
|
|
version 3.5.2 of APM:Plane. This is a minor release with small
|
|
|
|
|
changes.
|
|
|
|
|
|
|
|
|
|
The main reason for this release over 3.5.1 is a fix for a bug where
|
|
|
|
|
the px4io co-processor on a Pixhawk can run out of memory while
|
|
|
|
|
booting. This causes the board to be unresponsive on boot. It only
|
|
|
|
|
happens if you have a more complex servo setup and is caused by too
|
|
|
|
|
much memory used by the IO failsafe mixer.
|
|
|
|
|
|
|
|
|
|
The second motivation for this release is to fix an issue where during
|
|
|
|
|
a geofence altitude failsafe that happens at low speed an aircraft may
|
|
|
|
|
dive much further than it should to gain speed. This only happened if
|
|
|
|
|
the thrust line of the aircraft combined with low pitch integrator
|
|
|
|
|
gain led to the aircraft not compensating sufficiently with elevator
|
|
|
|
|
at full throttle in a TECS underspeed state. To fix this two changes
|
|
|
|
|
have been made:
|
|
|
|
|
|
|
|
|
|
- a minimum level of integrator in the pitch controller has been
|
|
|
|
|
added. This level has a sufficiently small time constant to avoid
|
|
|
|
|
the problem with the TECS controller in an underspeed state.
|
|
|
|
|
|
|
|
|
|
- the underspeed state in TECS has been modified so that underspeed
|
|
|
|
|
can end before the full target altitude has been reached, as long
|
|
|
|
|
as the airspeed has risen sufficiently past the minimum airspeed
|
|
|
|
|
for a sufficient period of time (by 15% above minimum airspeed for
|
|
|
|
|
3 seconds).
|
|
|
|
|
|
|
|
|
|
The default P gains for both roll and pitch have also been raised from
|
|
|
|
|
0.4 to 0.6. This is to help for users that fly with the default
|
|
|
|
|
parameters. A value of 0.6 is safe for all aircraft that I have
|
|
|
|
|
analysed logs for.
|
|
|
|
|
|
|
|
|
|
The default gains and filter frequencies of the QuadPlane code have
|
|
|
|
|
also been adjusted to better reflect the types of aircraft users have
|
|
|
|
|
been building.
|
|
|
|
|
|
|
|
|
|
Other changes include:
|
|
|
|
|
|
|
|
|
|
- improved QuadPlane logging for better analysis and tuning (adding
|
|
|
|
|
RATE and QTUN messages)
|
|
|
|
|
- fixed a bug introduced in 3.5.1 in rangefinder landing
|
|
|
|
|
- added TECS logging of speed_weight and flags
|
|
|
|
|
- improvements to the lsm303d driver for Linux
|
|
|
|
|
- improvements to the waf build system
|
|

The reverse thrust landing is particularly exciting as that adds a
|
2016-03-20 19:44:52 -03:00
|
|
|
whole new range of possibilities for landing in restricted areas. Many
|
|
|
|
|
thanks to Tom for the great work on getting this done.

|
I'd like to thank Holger for both his great work on this and his
|
|
|
|
|
patience given how long it has taken to be in a release. This adds

|
|
|

support for automatic canbus node assignment which makes setup much
|
|
|
|
|
easier, and also supports the latest versions of the Zubax canbus GPS.

My apologies if your favourite feature didn't make it into this
|
|
|
|
|
release! There are a lot more changes pending but we needed to call a
|
|
|
|
|
halt for the release eventually. This release has had a lot of flight
|
|
|
|
|
testing and I'm confident it will be a great release.
|

Happy flying!

Release 3.5.0, 30th January 2016
|
|
|
|
|
--------------------------------

The ArduPilot development team is proud to announce the release of
|
2016-01-29 22:04:51 -04:00
|
|
|
version 3.5.0 of APM:Plane. This is a major release with a lot of
|
2016-01-09 00:17:45 -04:00
|
|
|
changes so please read the notes carefully!
|
|
|
|
|
|
|
|
|
|
The biggest changes in this release are:
|
|
|
|
|
|
|
|
|
|
- switch to new EKF2 kalman filter for attitude and position estimation
|
|
|
|
|
- added support for parachutes
|
|
|
|
|
- added support for QuadPlanes
|
2016-01-09 02:09:05 -04:00
|
|
|
- support for 4 new flight boards, the QualComm Flight, the BHAT,
|
|
|
|
|
the PXFmini and the Pixracer
|
2016-01-09 00:17:45 -04:00
|
|
|
- support for arming on moving platforms
|
2016-01-29 22:04:51 -04:00
|
|
|
- support for better camera trigger logging
|
2016-01-09 00:17:45 -04:00
|
|
|
|
|
|
|
|
New Kalman Filter
|
|
|
|
|
|
|
|
|
|
The 3.4 release series was the first where APM:Plane used a Kalman
|
|
|
|
|
Filter by default for attitude and position estimation. It works very
|
|
|
|
|
well, but Paul Riseborough has been working hard recently on a new
|
|
|
|
|
EKF variant which fixes many issues seen with the old estimator. The
|
|
|
|
|
key improvements are:
|
|
|
|
|
|
|
|
|
|
- support for separate filters on each IMU for multi-IMU boards
|
|
|
|
|
(such as the Pixhawk), giving a high degree of redundency
|
|
|
|
|
- much better handling of gyro drift estimation, especially on
|
|
|
|
|
startup
|
|
|
|
|
- much faster recovery from attitude estimation errors
|
|
|
|
|
|
|
|
|
|
After extensive testing of the new EKF code we decided to make it the
|
|
|
|
|
default for this release. You can still use the old EKF if you want to
|
|
|
|
|
by setting AHRS_EKF_TYPE to 1, although it is recommended that the new
|
|
|
|
|
EKF be used for all aircraft.
|
|
|
|
|
|
|
|
|
|
Parachute Support
|
|
|
|
|
|
|
|
|
|
This is the first release with support for parachute landings on
|
|
|
|
|
plane. The configuration and use of a parachute is the same as the
|
|
|
|
|
existing copter parachute support. See
|
2016-04-23 17:55:58 -03:00

|
2016-01-09 00:17:45 -04:00
|
|
|
|
|
|
|
|
Note that parachute support is considered experimental in planes.
|
|
|
|
|
|
|
|
|
|
QuadPlane Support
|
|
|
|
|
|
|
|
|
|
This release includes support for hybrid plane/multi-rotors called
|
|
|
|
|
QuadPlanes. More details are available in this blog post:

|
2016-01-09 02:09:05 -04:00
|
|
|
Support for 4 new Flight Boards
|
2016-01-09 00:17:45 -04:00
|
|
|
|
|
|
|
|
The porting of ArduPilot to more flight boards continues, with support
|
|
|
|
|
for 3 new flight boards in this release. They are:
|
|
|
|
|
|
|
|
|
|
- the BHAT board
|
|
|
|
|
- the PXFmini
|
|
|
|
|
- the QualComm Flight
|
2016-01-09 02:09:05 -04:00
|
|
|
- the Pixracer
|
2016-01-09 00:17:45 -04:00
|
|
|
|
|
|
|
|
More information about the list of supported boards is available here:

|
|
|
|
|
|
|
|
Startup on a moving platform
|
|
|
|
|
|
|
|
|
|
One of the benefits of the new EKF2 estimator is that it allows for
|
|
|
|
|
rapid estimation of gyro offset without doing a gyro calibration on
|
|
|
|
|
startup. This makes it possible to startup and arm on a moving
|
|
|
|
|
platform by setting the INS_GYR_CAL parameter to zero (to disable gyro
|
|
|
|
|
calibration on boot). This should be a big help when flying off boats.
|
|
|
|

|
|
|
Improved Camera Trigger Logging
|
|
|
|
|
|
|
|
|
|
This release adds new CAM_FEEDBACK_PIN and CAM_FEEDBACK_POL
|
|
|
|
|
parameters. These add support for separate CAM and TRIG log messages,
|
|
|
|
|
where TRIG is logged when the camera is triggered and the CAM message
|
|
|
|
|
is logged when an external pin indicates the camera has actually
|
|
|
|
|
fired. This pin is typically based on the flash hotshoe of a camera
|
|
|
|
|
and provides a way to log the exact time of camera triggering more
|
|
|
|
|
accurately. Many thanks to Dario Andres and Jaime Machuca for their
|
|
|
|
|
work on this feature.

Release 3.4.0, 24th September 2015
|
|
|
|
|
----------------------------------
|
2015-08-19 22:11:12 -03:00
|

2015-09-23 21:08:27 -03:00
|
|
|
The ArduPilot development team is proud to announce the release of
|
|
|
|
|
version 3.4.0 of APM:Plane. This is a major release with a lot of
|
|
|
|
|
changes so please read the notes carefully!
|
2015-08-19 22:30:28 -03:00
|
|

|
2015-09-23 21:08:27 -03:00

|
First release with EKF by default
|
2015-08-19 22:30:28 -03:00
|
|
|
|
2015-09-23 21:08:27 -03:00
|
|
|
This is the also the first release that enables the EKF (Extended
|
|
|
|
|
Kalman Filter) for attitude and position estimation by default. This
|
|
|
|
|
has been in development for a long time, and significantly improves
|
|
|
|
|
flight performance. You can still disable the EKF if you want to using
|
|
|
|
|
the AHRS_EKF_USE parameter, but it is strongly recommended that you
|
|
|
|
|
use the EKF. Note that if an issue is discovered with the EKF in
|
|
|
|
|
flight it will automatically be disabled and the older DCM system will
|
|
|
|
|
be used instead. That should be very rare.
|
|
|
|
|
|
|
|
|
|
In order to use the EKF we need to be a bit more careful about the
|
|
|
|
|
setup of the aircraft. That is why in the last release we enabled
|
|
|
|
|
arming and pre-arm checks by default. Please don't disable the arming
|
|
|
|
|
checks, they are there for very good reasons.
|
|
|
|
|
|
|
|
|
|
Last release with APM1/APM2 support
|
|
|
|
|
|
|
|
|
|
This will be the last major release that supports the old APM1/APM2
|
|
|
|
|
AVR based boards. We have finally run out of flash space and
|
|
|
|
|
memory. In the last few releases we spent quite a bit of time trying
|
|
|
|
|
to squeeze more and more into the small flash space of the APM1/APM2,
|
|
|
|
|
but it had to end someday if ArduPilot is to continue to develop. I am
|
|
|
|
|
open to the idea of someone else volunteering to keep doing
|
|
|
|
|
development of APM1/APM2 so if you have the skills and inclination do
|
|
|
|
|
please get in touch. Otherwise I will only do small point release
|
|
|
|
|
changes for major bugs.
|
|
|
|
|
|
|
|
|
|
Even to get this release onto the APM1/APM2 we had to make sacrifices
|
|
|
|
|
in terms of functionality. The APM1/APM2 release is missing quite a
|
|
|
|
|
few features that are on the Pixhawk and other boards. For example:
|
|
|
|
|
|
|
|
|
|
- no rangefinder support for landing
|
|
|
|
|
- no terrain following
|
|
|
|
|
- no EKF support
|
|
|
|
|
- no camera control
|
|
|
|
|
- no CLI support
|
|
|
|
|
- no advanced failsafe support
|
|
|
|
|
- no HIL support (sorry!)
|
|
|
|
|
- support for far fewer GPS types
|
|
|
|
|
|
|
|
|
|
that is just the most obvious major features that are missing on
|
|
|
|
|
APM1/APM2. There are also numerous other smaller things where we need
|
|
|
|
|
to take shortcuts on the APM1/APM2. Some of these features were
|
|
|
|
|
available on older APM1/APM2 releases but needed to be removed to
|
|
|
|
|
allow us to squeeze the new release onto the board. So if you are
|
|
|
|
|
happy with a previous release on your APM2 and want a feature that is
|
|
|
|
|
in that older release and not in this one then perhaps you shouldn't
|
|
|
|
|
upgrade.
|
|
|
|
|
|
|
|
|
|
PID Tuning
|
|
|
|
|
|
|
|
|
|
While most people are happy with autotune to tune the PIDs for their
|
|
|
|
|
planes, it is nice also to be able to do fine tuning by hand. This
|
|
|
|
|
release includes new dataflash and mavlink messages to help with that
|
|
|
|
|
tuning. You can now see the individual contributions of the P, I and D
|
|
|
|
|
components of each PID in the logs, allowing you to get a much better
|
|
|
|
|
picture of the performance.
|
|
|
|
|
|
|
|
|
|
A simple application of this new tuning is you can easily see if your
|
|
|
|
|
trim is off. If the Pitch I term is constantly contributing a
|
|
|
|
|
signifcant positive factor then you know that ArduPilot is having to
|
|
|
|
|
constantly apply up elevator, which means your plane is nose
|
|
|
|
|
heavy. The same goes for roll, and can also be used to help tune your
|
|
|
|
|
ground steering.
|
|
|
|
|
|
|
|
|
|
Vibration Logging
|
|
|
|
|
|
|
|
|
|
This release includes a lot more options for diagnosing vibration
|
|
|
|
|
issues. You will notice new VIBRATION messages in MAVLink and VIBE
|
|
|
|
|
messages in the dataflash logs. Those give you a good idea of your
|
|
|
|
|
(unfiltered) vibration levels. For really detailed analysis you can
|
|
|
|
|
setup your LOG_BITMASK to include raw logging, which gives you every
|
|
|
|
|
accel and gyro sample on your Pixhawk. You can then do a FFT on the
|
|
|
|
|
result and plot the distribution of vibration level with
|
|
|
|
|
frequency. That is great for finding the cause of vibration
|
|
|
|
|
issues. Note that you need a very fast microSD card for that to work!
|
|
|
|
|
|
|
|
|
|
Rudder Disarm
|
|
|
|
|
|
|
|
|
|
This is the first release that allows you to disarm using the rudder
|
|
|
|
|
if you want to. It isn't enabled by default (due to the slight risk of
|
|
|
|
|
accidentially disarming while doing aerobatics). You can enable it
|
|
|
|
|
with the ARMING_RUDDER parameter by setting it to 2. It will only
|
|
|
|
|
allow you to disarm if the autopilot thinks you are not flying at the
|
|
|
|
|
time (thanks to the "is_flying" heuristics from Tom Pittenger).
|
|
|
|
|
|
|
|
|
|
More Sensors
|
|
|
|
|
|
|
|
|
|
This release includes support for a bunch more sensors. It now supports
|
|
|
|
|
3 different interfaces for the LightWare range of Lidars (serial, I2C
|
|
|
|
|
and analog), and also supports the very nice Septentrio RTK
|
|
|
|
|
dual-frequency GPS (the first dual-frequency GPS we have support
|
|
|
|
|
for). It also supports the new "blue label" Lidar from Pulsed Light
|
|
|
|
|
(both on I2C and PWM).
|
|
|
|
|
|
|
|
|
|
For the uBlox GPS, we now have a lot more configurability of the
|
|
|
|
|
driver, with the ability to set the GNSS mode for different
|
|
|
|
|
constellations. Also in the uBlox driver we support logging of the raw
|
|
|
|
|
carrier phase and pseudo range data, which allows for post-flight RTK
|
|
|
|
|
analysis with raw-capable receivers for really accurate photo
|
|
|
|
|
missions.
|
|
|
|
|
|
|
|
|
|
Better Linux support
|
|
|
|
|
|
|
|
|
|
This release includes a lot of improvements to the Linux based
|
|
|
|
|
autopilot boards, including the NavIO+, the PXF and ERLE boards and
|
|
|
|
|
the BBBMini and the new RasPilot board. If you like the idea of flying
|
|
|
|
|
with Linux then please try it out!
|
|
|
|
|
|
|
|
|
|
On-board compass calibrator
|
|
|
|
|
|
|
|
|
|
We also have a new on-board compass calibrator, which also adds calibration
|
|
|
|
|
for soft iron effects, allowing for much more accurate compass
|
|
|
|
|
calibration. Support for starting the compass calibration in the
|
|
|
|
|
various ground stations is still under development, but it looks like
|
|
|
|
|
this will be a big improvement to compass calibration.
|
|
|
|
|
|
|
|
|
|
Lots of other changes!
|
|
|
|
|
|
|
|
|
|
The above list is just a taste of the changes that have gone into this
|
|
|
|
|
release. Thousands of small changes have gone into this release with
|
|
|
|
|
dozens of people contributing. Many thanks to everyone who helped!

Release 3.3.0, 20th May 2015
|
|
|
|
|
----------------------------
|
2015-04-30 01:07:30 -03:00

|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.3.0 of APM:Plane. This is a major release with a lot of
|
|
|
|
|
changes. Please read the release notes carefully!
|
2015-04-30 01:07:30 -03:00
|
|
|
|
2015-05-20 05:01:21 -03:00
|
|
|
The last stable release was 3 months ago, and since that time we have
|
|
|
|
|
applied over 1200 changes to the code. It has been a period of very
|
|
|
|
|
rapid development for ArduPilot. Explaining all of the changes that
|
|
|
|
|
have been made would take far too long, so I've chosen some key
|
|
|
|
|
changes to explain in detail, and listed the most important secondary
|
|
|
|
|
changes in a short form. Please ask for details if there is a change
|
|
|
|
|
you see listed that you want some more information on.
|
|
|
|
|
|
|
|
|
|
Arming Changes
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
This is the first release of APM:Plane where ARMING_CHECK and
|
|
|
|
|
ARMING_REQUIRE both default to enabled. That means when you upgrade if
|
|
|
|
|
you didn't previously have arming enabled you will need to learn about
|
|
|
|
|
arming your plane.
|
|
|
|
|
|
|
|
|
|
Please see this page for more information on arming:
|
|
|
|
|
|
|
|
|
|
http://plane.ardupilot.com/wiki/arming-your-plane/
|
|
|
|
|
|
|
|
|
|
I know many users will be tempted to disable the arming checks, but
|
|
|
|
|
please don't do that without careful thought. The arming checks are an
|
|
|
|
|
important part of ensuring the aircraft is ready to fly, and a common
|
|
|
|
|
cause of flight problems is to takeoff before ArduPilot is ready.
|
|
|
|
|
|
|
|
|
|
Re-do Accelerometer Calibration
|
|
|
|
|
-------------------------------
|
|
|
|
|
|
|
|
|
|
Due to a change in the maximum accelerometer range on the Pixhawk all
|
|
|
|
|
users must re-do their accelerometer calibration for this release. If
|
|
|
|
|
you don't then your plane will fail to arm with a message saying that
|
|
|
|
|
you have not calibrated the accelerometers.
|
|
|
|
|
|
|
|
|
|
Only 3D accel calibration
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
The old "1D" accelerometer calibration method has now been removed, so
|
|
|
|
|
you must use the 3D accelerometer calibration method. The old method
|
|
|
|
|
was removed because a significant number of users had poor flights due
|
|
|
|
|
to scaling and offset errors on their accelerometers when they used
|
|
|
|
|
the 1D method. My apologies for people with very large aircraft who
|
|
|
|
|
find the 3D method difficult.
|
|
|
|
|
|
|
|
|
|
Note that you can do the accelerometer calibration with the autopilot
|
|
|
|
|
outside the aircraft which can make things easier for large aircraft.
|
|
|
|
|
|
|
|
|
|
Auto-disarm
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
After an auto-landing the autopilot will now by default disarm after
|
|
|
|
|
LAND_DISARMDELAY seconds (with a default of 20 seconds). This feature
|
|
|
|
|
is to prevent the motor from spinning up unexpectedly on the ground
|
|
|
|
|
after a landing.
|
|
|
|
|
|
|
|
|
|
HIL_MODE parameter
|
|
|
|
|
------------------
|
|
|
|
|
|
|
|
|
|
It is now possible to configure your autopilot for hardware in the
|
|
|
|
|
loop simulation without loading a special firmware. Just set the
|
|
|
|
|
parameter HIL_MODE to 1 and this will enable HIL for any
|
|
|
|
|
autopilot. This is designed to make it easier for users to try HIL
|
|
|
|
|
without having to find a HIL firmware.
|
|
|
|
|
|
|
|
|
|
SITL on Windows
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
The SITL software in the loop simulation system has been completely
|
|
|
|
|
rewritten for this release. A major change is to make it possible to
|
|
|
|
|
run SITL on native windows without needing a Linux virtual
|
|
|
|
|
machine. There should be a release of MissionPlanner for Windows soon
|
|
|
|
|
which will make it easy to launch a SITL instance.
|
|
|
|
|
|
|
|
|
|
The SITL changes also include new backends, including the CRRCSim
|
|
|
|
|
flight simulator. This gives us a much wider range of aircraft we can
|
|
|
|
|
use for SITL. See http://dev.ardupilot.com/wiki/simulation-2/ for more
|
|
|
|
|
information.
|
|
|
|
|
|
|
|
|
|
Throttle control on takeoff
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
A number of users had problems with pitch control on auto-takeoff, and
|
|
|
|
|
with the aircraft exceeding its target speed during takeoff. The
|
|
|
|
|
auto-takeoff code has now been changed to use the normal TECS throttle
|
|
|
|
|
control which should solve this problem.
|
|
|
|
|
|
|
|
|
|
Rudder only support
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
There is a new RUDDER_ONLY parameter for aircraft without ailerons,
|
|
|
|
|
where roll is controlled by the rudder. Please see the documentation
|
|
|
|
|
for more information on flying with a rudder only aircraft:
|
|
|
|
|
|
|
|
|
|
http://plane.ardupilot.com/wiki/arduplane-parameters/#rudder_only_aircraft_arduplanerudder_only
|
|
|
|
|
|
|
|
|
|
APM1/APM2 Support
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
We have managed to keep support for the APM1 and APM2 in this release,
|
|
|
|
|
but in order to fit it in the limited flash space we had to disable
|
|
|
|
|
some more features when building for those boards. For this release
|
|
|
|
|
the AP_Mount code for controlling camera mounts is disabled on
|
|
|
|
|
APM1/APM2.
|
|
|
|
|
|
|
|
|
|
At some point soon it will become impractical to keep supporting the
|
|
|
|
|
APM1/APM2 for planes. Please consider moving to a 32 bit autopilot
|
|
|
|
|
soon if you are still using an APM1 or APM2.
|
|
|
|
|
|
|
|
|
|
New INS code
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
There have been a lot of changes to the gyro and accelerometer
|
|
|
|
|
handling for this release. The accelerometer range on the Pixhawk has
|
|
|
|
|
been changed to 16g from 8g to prevent clipping on high vibration
|
|
|
|
|
aircraft, and the sampling rate on the lsm303d has been increased to
|
|
|
|
|
1600Hz.
|
|
|
|
|
|
|
|
|
|
An important bug has also been fixed which caused aliasing in the
|
|
|
|
|
sampling process from the accelerometers. That bug could cause
|
|
|
|
|
attitude errors in high vibration environments.
|
|
|
|
|
|
|
|
|
|
Numerous Landing Changes
|
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
|
|
Once again there have been a lot of improvements to the automatic
|
|
|
|
|
landing support. Perhaps most important is the introduction of a
|
|
|
|
|
smooth transition from landing approach to the flare, which reduces
|
|
|
|
|
the tendency to pitch up too much on flare.
|
|
|
|
|
|
|
|
|
|
There is also a new parameter TECS_LAND_PMAX which controls the
|
|
|
|
|
maximum pitch during landing. This defaults to 10 degrees, but for
|
|
|
|
|
many aircraft a smaller value may be appropriate. Reduce it to 5
|
|
|
|
|
degrees if you find you still get too much pitch up during the flare.
|
|
|
|
|
|
|
|
|
|

Release 3.2.2, February 10th 2015
|
|
|
|
|
---------------------------------
|
|
|
|
|
|
|
|
|
|
The ardupilot development team has released version 3.2.2 of
|
|
|
|
|
APM:Plane. This is a bugfix release for some important bugs found by
|
|
|
|
|
users of the 3.2.1 release.
|
|
|
|
|
|
|
|
|
|
The changes in this release are:
|
|
|
|
|
|
|
|
|
|
- fixed a bug that could cause short term loss of RC control with
|
|
|
|
|
some receiver systems and configurations
|
|
|
|
|
|
|
|
|
|
- allowed for shorter sync pulse widths for PPM-SUM receivers on
|
|
|
|
|
APM1 and APM2
|
|
|
|
|
|
|
|
|
|
- fixed HIL mode altitude
|
|
|
|
|
|
|
|
|
|
The most important bug fix is the one for short term loss of RC
|
|
|
|
|
control. This is a very long standing bug which didn't have a
|
2016-05-12 14:10:49 -03:00
|
|
|
noticeable impact for most people, but could cause loss of RC control
|
2015-02-09 18:53:11 -04:00
|
|
|
for around 1 or 2 seconds for some people in certain circumstances.
|
|
|
|
|
|
|
|
|
|
The bug was in the the AP_HAL RCInput API. Each HAL backend has a flag
|
|
|
|
|
that says whether there is a new RC input frame available. That flag
|
|
|
|
|
was cleared by the read() method (typically hal.rcin->read()). Callers
|
|
|
|
|
would check for new input by checking the boolean
|
|
|
|
|
hal.rcin->new_input() function.
|
|
|
|
|
|
|
|
|
|
The problem was that read() was called from multiple places. Normally
|
|
|
|
|
this is fine as reads from other than the main radio input loop happen
|
|
|
|
|
before the other reads, but if the timing of the new radio frame
|
|
|
|
|
exactly matched the loop frequency then a read from another place
|
|
|
|
|
could clear the new_input flag and we would not see the new RC input
|
|
|
|
|
frame. If that happened enough times we would go into a short term RC
|
|
|
|
|
failsafe and ignore RC inputs, even in manual mode.
|
|
|
|
|
|
|
|
|
|
The fix was very simple - it is the new_input() function itself that
|
|
|
|
|
should clear the flag, not read().
|
|
|
|
|
|
|
|
|
|
Many thanks to MarkM for helping us track down this bug by providing
|
|
|
|
|
us with sufficient detail on how to reproduce it. In Marks case his
|
|
|
|
|
OpenLRSng configuration happened to produce exactly the worst case
|
|
|
|
|
timing needed to reproduce the issue. Once I copied his OpenLRS
|
|
|
|
|
settings to my TX/RX I was able to reproduce the problem and it was
|
|
|
|
|
easy to find and fix.
|
|
|
|
|
|
|
|
|
|
A number of users have reported occasional glitches in manual control
|
|
|
|
|
where servos pause for short periods in past releases. It is likely
|
|
|
|
|
that some of those issues were caused by this bug. The dev team would
|
|
|
|
|
like to apologise for taking so long to track down this bug!
|
|
|
|
|
|
|
|
|
|
The other main change was also related to RC input. Some receivers use
|
|
|
|
|
a PPM-SUM sync pulse width shorter than what the APM1/APM2 code was
|
|
|
|
|
setup to handle. The OpenLRSng default sync pulse width is 3000
|
|
|
|
|
microseconds, but the APM1/APM2 code was written for a mininum sync
|
|
|
|
|
pulse width of 4000 microseconds. For this release I have changed the
|
|
|
|
|
APM1/APM2 driver to accept a sync pulse width down to 2700
|
|
|
|
|
microseconds.

Release 3.2.0, November 25th 2014
|
|
|
|
|
---------------------------------
|
2014-11-15 23:41:29 -04:00
|
|
|
|
|
|
|
|
The ardupilot development team is proud to announce the release of
|
2014-11-24 22:58:28 -04:00
|
|
|
version 3.2.0 of APM:Plane. This is a major release with a lot of
|
2014-11-15 23:41:29 -04:00
|
|
|
new features.
|
|
|
|
|
|
2014-11-24 22:58:28 -04:00
|
|
|
The changes span a lot of different areas of the code, but arguably
|
|
|
|
|
the most important changes are:
|
|
|
|
|
|
|
|
|
|
- automatic stall prevention code
|
|
|
|
|
- PX4IO based RC override code on FMU failure
|
|
|
|
|
- I2C crash bugfix
|
|
|
|
|
- new autoland code from Michael Day
|
|
|
|
|
- compass independent auto takeoff
|
|
|
|
|
|
|
|
|
|
I'll go into each of these changes in a bit more detail.
|
|
|
|
|
|
|
|
|
|
Automatic Stall Prevention
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
The automatic stall prevention code is code that uses the aerodynamic
|
|
|
|
|
load factor (calculated from demanded bank angle) to adjust both the
|
|
|
|
|
maximum roll angle and the minimum airspeed. You can enable/disable
|
|
|
|
|
this code with the STALL_PREVENTION parameter which defaults to
|
|
|
|
|
enabled.
|
|
|
|
|
|
|
|
|
|
When in stabilised manual throttle modes this option has the effect of
|
|
|
|
|
limiting how much bank angle you can demand when close to the
|
|
|
|
|
configured minimum airspeed (from ARSPD_FBW_MIN). That means when in
|
|
|
|
|
FBWA mode if you try to turn hard while close to ARSPD_FBW_MIN it will
|
|
|
|
|
limit the bank angle to an amount that will keep the speed above
|
|
|
|
|
ARSPD_FBW_MIN times the aerodynamic load factor. It will always allow
|
|
|
|
|
you at bank at least 25 degrees however, to ensure you keep some
|
|
|
|
|
maneuverability if the airspeed estimate is incorrect.
|
|
|
|
|
|
|
|
|
|
When in auto-throttle modes (such as AUTO, RTL, CRUISE etc) it will
|
|
|
|
|
additionally raise the minimum airspeed in proportion to the
|
|
|
|
|
aerodynamic load factor. That means if a mission demands a sharp turn
|
|
|
|
|
at low speed then initially the turn will be less sharp, and the TECS
|
|
|
|
|
controller will add power to bring the airspeed up to a level that can
|
|
|
|
|
handle the demanded turn. After the turn is complete the minimum
|
|
|
|
|
airspeed will drop back to the normal level.
|
|
|
|
|
|
|
|
|
|
This change won't completely eliminate stalls of course, but it should
|
|
|
|
|
make them less likely if you properly configure ARSPD_FBW_MIN for your
|
|
|
|
|
aircraft.
|
|
|
|
|
|
|
|
|
|
PX4IO based RC override code
|
|
|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
This releases adds support for PX4IO based RC override. This is a
|
|
|
|
|
safety feature where the stm32 IO co-processor on the PX4 and Pixhawk
|
|
|
|
|
will give the pilot manual control if the main ArduPilot
|
|
|
|
|
micro-controller fails (or the autopilot code crashes). This is
|
|
|
|
|
particularly useful when testing new code that may not be stable.
|
|
|
|
|
|
|
|
|
|
As part of this new RC override support we also have a new
|
|
|
|
|
OVERRIDE_CHAN parameter, which allows you to specify a RC input
|
|
|
|
|
channel which can be used to test the RC override support. See the
|
|
|
|
|
documentation on OVERRIDE_CHAN for details.
|
|
|
|
|
|
|
|
|
|
I2C bugfix
|
|
|
|
|
----------
|
|
|
|
|
|
|
|
|
|
This release fixes another I2C bug in NuttX which could cause the
|
|
|
|
|
Pixhawk to lock up under high I2C load with noise on I2C cables. This
|
|
|
|
|
bug has caused at least two aircraft to crash, so it is an important
|
|
|
|
|
fix. I hope this will be the last I2C crash bug we find in NuttX! An
|
|
|
|
|
audit of the code was done to try to confirm that no more bugs of this
|
|
|
|
|
type are present.
|
|
|
|
|
|
|
|
|
|
New Autoland code
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
This release incorporates some new autoland capabilities contributed
|
|
|
|
|
by Michael Day. The key new feature is the ability to trigger an
|
|
|
|
|
automatic landing when a RTL completes, which for the first time
|
|
|
|
|
allows a user to setup their aircraft to land using only transmitter
|
|
|
|
|
control.
|
|
|
|
|
|
|
|
|
|
The way it works is there is a new parameter RTL_AUTOLAND. If that is
|
|
|
|
|
set to 1 and the aircraft reaches its target location in an RTL it
|
|
|
|
|
will look for DO_LAND_START mission item in the mission. If that is
|
|
|
|
|
found then the aircraft will switch to AUTO starting at that section
|
|
|
|
|
of the mission. The user sets up their land mission commands starting
|
|
|
|
|
with a DO_LAND_START mission item.
|
|
|
|
|
|
|
|
|
|
There is more to do in this autoland support. We have been discussing
|
|
|
|
|
more advanced go-around capabilities and also better path planning for
|
|
|
|
|
landing. The code in this release is an important first step though,
|
|
|
|
|
and will be a good basis for future work.
|
|
|
|
|
|
|
|
|
|
Compass independent takeoff code
|
|
|
|
|
--------------------------------
|
|
|
|
|
|
|
|
|
|
The auto-takeoff code has been changed to make it more independent of
|
|
|
|
|
compass settings, allowing for reliable takeoff down a runway with
|
|
|
|
|
poor compass offsets. The new takeoff code uses the gyroscope as the
|
|
|
|
|
primary heading control for the first part of the takeoff, until the
|
|
|
|
|
aircraft gains enough speed for a GPS heading to be reliable.
|
|
|

|
|
|

|
I hope that everyone enjoys flying this new APM:Plane release as much
|
|
|
|
|
as we enjoyed producing it! It is a major milestone in the development
|
|
|
|
|
of the fixed wing code for APM, and I think puts us in a great
|
|
|
|
|
position for future development.
|
|

Release 3.1.1, September 12th 2014
|
|
|
|
|
----------------------------------
|
|
|
|
|
|
|
|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.1.1 of APM:Plane. This is primarily a bugfix release with a
|
|
|
|
|
small number of new features.
|
|
|
|
|
|
|
|
|
|
The main bug fixed in this release is a bug that could affect saving
|
|
|
|
|
parameters and mission items in the FRAM/eeprom storage of
|
|
|
|
|
PX4v1/Pixhawk/VRBrain. The bug has been in the code since January 2013
|
|
|
|
|
and did not cause problems very often (which is why it hasn't been
|
|
|
|
|
noticed till now), but when it does happen it causes changes to
|
|
|
|
|
parameters or mission items not to be saved on a reboot.
|
|
|
|
|
|
|
|
|
|
Other changes in this release:
|
|
|
|
|
|
|
|
|
|
- support for using a Lidar for landing for terrain altitude (see
|
|
|
|
|
the RNGFND_LANDING parameter)
|
|
|
|
|
|
|
|
|
|
- improvements in the landing approach code, especially the glide
|
|
|
|
|
slope calculation
|
|
|
|
|
|
|
|
|
|
- added LAND_FLAP_PERCENT and TKOFF_FLAP_PCNT parameters, to control
|
|
|
|
|
the amount of flaps to use on takeoff and landing
|
|
|
|
|
|
|
|
|
|
- the default WP_RADIUS has been raised from 30 to 90. Note that the
|
|
|
|
|
L1 controller may choose to turn after the WP_RADIUS is
|
|
|
|
|
reached. The WP_RADIUS only controls the earliest point at which
|
|
|
|
|
the turn can happen, so a larger WP_RADIUS usually leads to better
|
|
|
|
|
flight paths, especially for faster aircraft.
|
|
|
|
|
|
|
|
|
|
- send gyro and accel status separately to the GCS (thanks to Randy)
|
|
|
|
|
|
|
|
|
|
- support setting the acceptance radius in mission waypoints (in
|
|
|
|
|
parameter 2), which allows for better control of waypoints where
|
|
|
|
|
actions such as servo release will happen
|
|
|
|
|
|
|
|
|
|
- fixed GPS time offset in HIL
|
|
|
|
|
|
|
|
|
|
- added RELAY_DEFAULT parameter, allowing control of relay state on
|
|
|
|
|
boot
|
|
|
|
|
|
|
|
|
|
- fixed sdcard logging on PX4v1
|
|
|
|
|
|
|
|
|
|
- added GPS_SBAS_MODE and GPS_MIN_ELEV parameters for better control
|
|
|
|
|
of the use of SBAS and the GPS elevation mask for advanced users
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.1.0, August 26th 2014
|
2014-08-07 01:10:49 -03:00
|
|
|
-------------------------------
|
|
|

2014-08-25 17:20:37 -03:00
|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.1.0 of APM:Plane. This is a major release with a lot of new
|
|
|
|
|
features and bug fixes.
|
|
|
|
|
|
|
|
|
|
The biggest change in this release is the addition of automatic
|
|
|
|
|
terrain following. Terrain following allows the autopilot to guide the
|
|
|
|
|
aircraft over varying terrain at a constant height above the ground
|
|
|
|
|
using an on-board terrain database.
|
2014-08-07 01:10:49 -03:00
|
|
|
|
|
|
|
|
Changes in this release:
|
|
|
|
|
|
|
|
|
|
- added terrain following support. See
|
|
|
|
|
http://plane.ardupilot.com/wiki/common-terrain-following/
|
|
|
|
|
|
|
|
|
|
- added support for higher baudrates on telemetry ports, to make it
|
2014-08-25 17:20:37 -03:00
|
|
|
easier to use high rate telemetry to companion boards. Rates of up
|
|
|
|
|
to 1.5MBit are now supported to companion boards.
|
2014-08-07 01:10:49 -03:00
|
|
|
|
|
|
|
|
- added new takeoff code, including new parameters:
|
|
|
|
|
TKOFF_TDRAG_ELEV, TKOFF_TDRAG_SPD1, TKOFF_ROTATE_SPD,
|
2014-08-25 17:20:37 -03:00
|
|
|
TKOFF_THR_SLEW and TKOFF_THR_MAX.
|
|
|
|
|
This gives fine grained control of auto takeoff for tail dragger aircraft.
|
2014-08-07 01:10:49 -03:00
|
|
|
|
|
|
|
|
- overhauled glide slope code to fix glide slope handling in many
|
2014-08-25 17:20:37 -03:00
|
|
|
situations. This makes transitions between different altitudes
|
|
|
|
|
much smoother.
|
2014-08-07 01:10:49 -03:00
|
|
|
|
2014-08-25 17:20:37 -03:00
|
|
|
- prevent early waypoint completion for straight ahead
|
|
|
|
|
waypoints. This makes for more accurate servo release at specific
|
|
|
|
|
locations, for applications such as dropping water bottles.
|
2014-08-07 01:10:49 -03:00
|
|
|
|
|
|
|
|
- added MAV_CMD_DO_INVERTED_FLIGHT command in missions, to change
|
2014-08-25 17:20:37 -03:00
|
|
|
from normal to inverted flight in AUTO (thanks to Philip Rowse for
|
|
|

Release 3.0.3, May 19th 2014
|
|
|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.0.3 of APM:Plane. This release contains some important bug
|
|
|
|
|
fixes for all supported boards.
|
|
|
|
|
|
|
|
|
|
The key bug fixes in this release are:
|
|
|
|
|
|
|
|
|
|
- fixed handling of filter divergance in the EKF filter
|
|
|
|
|
- fixed a glide slope calculation bug when entering AUTO mode
|
|
|
|
|
|
|
|
|
|
The EKF fixes are the main focus of this release. During testing of
|
|
|
|
|
APM:Plane with the AHRS_EKF_USE enabled it was found that under some
|
|
|
|
|
circumstances the EKF could diverge, resulting in loss of attitude
|
|
|
|
|
estimate. Unless the pilot quickly took control in MANUAL this could
|
|
|
|
|
result in the aircraft crashing.
|
|
|
|
|
|
|
|
|
|
The fix for this problem was in several parts. The main fix was to
|
|
|
|
|
prevent the divergance, but as a precuation against future bugs of
|
|
|
|
|
this type additional numerical checks were added to allow the EKF to
|
|
|
|
|
automatically reset in flight when the internal state shows
|
|
|
|
|
large gyro bias changes, which are the first sign of something going
|
|
|
|
|
wrong in the filter. If this happens again the EKF will automatically
|
|
|
|
|
disable itself for 10 seconds, allowing APM:Plane to fall back to the
|
|
|
|
|
old DCM code. The EKF will then reset itself using initial state based
|
|
|
|
|
on the DCM state. The aircraft will report the failure using the AHRS
|
|
|
|
|
health bit in the SYS_STATUS MAVLink message.
|
|
|
|
|
|
|
|
|
|
The default EKF tuning parameters were also updated based on a number
|
|
|
|
|
of user supplied flight logs to increase the robustness of the filter.
|
|
|
|
|
|
|
|
|
|
The second bug fixed in this release relates to the glide slope
|
|
|
|
|
calculation when the aircraft enters AUTO mode for the first time when
|
|
|
|
|
at an altitude above the altitude of the first waypoint in the
|
|
|
|
|
mission. The starting point for the glide slope was incorrectly
|
|
|
|
|
calculated using the home altitude, which resulted in the aircraft
|
|
|
|
|
descending below the first waypoint altitude before climbing again. In
|
|
|
|
|
some circumstances this could lead to a crash due to local terrain.
|
|
|
|
|
|
|
|
|
|
Many thanks to everyone who tested this release. Special thanks to
|
|
|
|
|
Dellarb for reporting the glide slope bug and to Paul Riseborough for
|
|
|
|
|
all his work on the EKF code over the last few weeks.
|
|
|
|
|
|
|
|
|
|
Happy flying!

Release 3.0.2, May 4th 2014
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.0.2 of APM:Plane. This release combines some important bug
|
|
|
|
|
fixes with some new features.
|
|
|
|
|
|
|
|
|
|
I2C bug fix
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
The most important change for this release is a bug fix for an I2C bug
|
|
|
|
|
in the NuttX I2C driver code that could (under some rare
|
|
|
|
|
circumstances) cause a Pixhawk to crash. This bug fix is the primary
|
|
|
|
|
reason for doing a new release now.
|
|
|
|
|
|
|
|
|
|
This bug was able to be reproduced by creating a 1.3m GPS cable
|
|
|
|
|
carrying both the I2C signals for a magnetometer and the UART signals
|
|
|
|
|
for the GPS. Interference between these two signals could cause the
|
|
|
|
|
I2C controller to give spurious data to the I2C driver. The I2C driver
|
|
|
|
|
did not have sufficient protection against these errors and could
|
|
|
|
|
crash the board.
|
|
|
|
|
|
|
|
|
|
While we have not been able to reproduce this error with the normal
|
|
|
|
|
cables that come with a Pixhawk we cannot rule out the bug triggering
|
|
|
|
|
with shorter cables, so we are doing a fast release to fix the bug.
|
|
|
|
|
|
|
|
|
|
Autotune
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
This release also includes an important new feature - automatic
|
|
|
|
|
roll/pitch tuning. While this feature is still considered experimental
|
|
|
|
|
we have had very positive feedback from beta testers and have decided
|
|
|
|
|
to include it in the release.
|
|
|
|
|
|
|
|
|
|
Full documentation for how to use automatic tuning is available here:
|
|
|
|
|
|
|
|
|
|
http://plane.ardupilot.com/wiki/automatic-tuning-with-autotune/
|
|
|
|
|
|
|
|
|
|
we hope that the automatic tuning will help users who have had
|
|
|
|
|
difficulty with the standard APM:Plane manual tuning procedure. We
|
|
|
|
|
plan on extending autotune to other aspects of fixed wing tuning in
|
|
|
|
|
future releases.
|
|
|
|
|
|
|
|
|
|

Release 3.0.1, April 9th 2014
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
I've just released APM:Plane 3.0.1, a bug fix release for the 3.0.0 release.
|
|
|
|
|
This release fixes two bugs:
|
|
|
|
|
|
|
|
|
|
throttle failsafe for aircraft using PWM level for failsafe detection
|
|
|
|
|
wind reporting with EKF enabled and no airspeed sensor
|
|
|
|
|
|
|
|
|
|
The throttle failsafe fix is a critical bugfix, which is why I am
|
|
|
|
|
doing a new release so soon. The bug was found by Sam Tabor, and he
|
|
|
|
|
posted the bug report before the 3.0.0 release, but I didn't notice it
|
|
|
|
|
in the release preparations. The bug only affects systems using PWM
|
|
|
|
|
value as the sole method of detecting loss of RC control. I hadn't
|
|
|
|
|
noticed it myself as my planes all use receivers which stop sending
|
|
|
|
|
value PWM frames when the RC link is lost. In that case failsafe
|
|
|
|
|
worked correctly. Receivers that keep sending PWM frames but with low
|
|
|
|
|
throttle levels are common though, so this is a very important fix.
|
|
|
|
|
Many thanks to Sam for reporting the bug, and my apologies for not
|
|
|
|
|
noticing it in time for the 3.0.0 release.

Release 3.0.0, April 8th 2014
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
The ardupilot development team is proud to announce the release of
|
|
|
|
|
version 3.0.0 of APM:Plane. This is a major release with a lot of new
|
|
|
|
|
features.
|
|
|
|
|
|
|
|
|
|
For each release I try to highlight the two or 3 key new features that
|
|
|
|
|
have gone in since the last release. That is a more difficult task
|
|
|
|
|
this time around because there are just so many new things. Still, I
|
|
|
|
|
think the most important ones are the new Extended Kalman Filter (EKF)
|
|
|
|
|
for attitude/position estimation, the extensive dual sensors support
|
|
|
|
|
and the new AP_Mission library.
|
|
|
|
|
|
|
|
|
|
We have also managed to still keep support for the APM1 and APM2,
|
|
|
|
|
although quite a few of the new features are not available on those
|
|
|
|
|
boards. We don't yet know for how long we'll be able to keep going on
|
|
|
|
|
supporting these old boards, so if you are thinking of getting a new
|
|
|
|
|
board then you should get a Pixhawk, and if you want the best
|
|
|
|
|
performance from the APM:Plane code then you should swap to a
|
|
|
|
|
Pixhawk now. It really is a big improvement.
|
|
|
|
|
|
|
|
|
|
New Extended Kalman Filter
|
|
|
|
|
--------------------------
|
|
|
|
|
|
|
|
|
|
The biggest change for the 3.0.0 release (and in fact the major reason
|
|
|
|
|
why we are calling it 3.0.0) is the new Extended Kalman Filter from
|
|
|
|
|
Paul Riseborough. Using an EKF for attitude and position estimation
|
|
|
|
|
was never an option on the APM2 as it didn't have the CPU power or
|
|
|
|
|
memory to handle it. The Pixhawk does have plenty of floating point
|
|
|
|
|
performance, and Paul has done a fantastic job of taking full
|
|
|
|
|
advantage of the faster board.
|
|
|
|
|
|
|
|
|
|
As this is the first stable release with the EKF code we have decided
|
|
|
|
|
to not enable it by default. It does however run all the time in
|
|
|
|
|
parallel with the existing DCM code, and both attitude/position
|
|
|
|
|
solutions are logged both to the on-board SD card and over
|
|
|
|
|
MAVLink. You can enable the EKF code using the parameter
|
|
|
|
|
AHRS_EKF_USE=1, which can be set and unset while flying, allowing you
|
|
|
|
|
to experiment with using the EKF either by examining your logs with
|
|
|
|
|
the EKF disabled to see how it would have done or by enabling it while
|
|
|
|
|
flying.
|
|
|
|
|
|
|
|
|
|
The main thing you will notice with the EKF enabled is more accurate
|
|
|
|
|
attitude estimation and better handling of sensor glitches. A Kalman
|
|
|
|
|
filter has an internal estimate of the reliability of each of its
|
|
|
|
|
sensor inputs, and is able to weight them accordingly. This means that
|
|
|
|
|
if your accelerometers start giving data that is inconsistent with
|
|
|
|
|
your other sensors then it can cope in a much more graceful way than
|
|
|
|
|
our old DCM code.
|
|
|
|
|
|
|
|
|
|
The result is more accurate flying, particularly in turns. It also
|
|
|
|
|
makes it possible to use higher tuning gains, as the increased
|
|
|
|
|
accuracy of the attitude estimation means that you can push the
|
|
|
|
|
airframe harder without it becoming unstable. You may find you can use
|
|
|
|
|
a smaller value for NAVL1_PERIOD, giving tighter turns, and higher
|
|
|
|
|
gains on your roll and pitch attitude controllers.
|
|
|
|
|
|
|
|
|
|
Paul has written up a more technical description of the new EKF code

|
|
|
Dual Sensors
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
The second really big change for this release is support for
|
|
|
|
|
dual-sensors. We now take full advantage of the dual accelerometers
|
|
|
|
|
and dual gyros in the Pixhawk, and can use dual-GPS for GPS
|
|
|
|
|
failover. We already had dual compass support, so the only main
|
|
|
|
|
sensors we don't support two of now are the barometer and the airspeed
|
|
|
|
|
sensor. I fully expect we will support dual baro and dual airspeed in
|
|
|
|
|
a future release.
|
|
|
|
|
|
|
|
|
|
You might wonder why dual sensors is useful, so let me give you an
|
|
|
|
|
example. I fly a lot of nitro and petrol planes, and one of my planes
|
|
|
|
|
(a BigStik 60) had a strange problem where it would be flying
|
|
|
|
|
perfectly in AUTO mode, then when the throttle reached a very specific
|
|
|
|
|
level the pitch solution would go crazy (sometimes off by 90
|
|
|
|
|
degrees). I managed to recover in MANUAL each time, but it certainly
|
|
|
|
|
was exciting!
|
|
|
|
|
|
|
|
|
|
A careful analysis of the logs showed that the culprit was
|
|
|
|
|
accelerometer aliasing. At a very specific throttle level the Z
|
|
|
|
|
accelerometer got a DC offset of 11 m/s/s. So when the plane was
|
|
|
|
|
flying along nice and level the Z accelerometer would change from -10
|
|
|
|
|
m/s/s to +1 m/s/s. That resulted in massive errors in the attitude
|
|
|
|
|
solution.
|
|
|
|
|
|
|
|
|
|
This sort of error happens because of the way the accelerometer is
|
|
|
|
|
sampled. In the APM code the MPU6000 (used on both the APM2 and
|
|
|
|
|
Pixhawk) samples the acceleration at 1kHz. So if you have a strong
|
|
|
|
|
vibrational mode that is right on 1kHz then you are sampling the "top
|
|
|
|
|
of the sine wave", and get a DC offset.
|
|
|
|
|
|
|
|
|
|
The normal way to fix this issue is to improve the physical
|
|
|
|
|
anti-vibration mounting in the aircraft, but I don't like to fix
|
|
|
|
|
problems like this by making changes to my aircraft, as if I fix my
|
|
|
|
|
aircraft it does nothing for the thousands of other people running the
|
|
|
|
|
same code. As the lead APM developer I instead like to fix things in
|
|
|
|
|
software, so that everyone benefits.
|
|
|
|
|
|
|
|
|
|
The solution was to take advantage of the fact that the Pixhawk has
|
|
|
|
|
two accelerometers, one is a MPU6000, and the 2nd is a LSM303D. The
|
|
|
|
|
LSM303D is sampled at 800Hz, whereas the MPU6000 is sampled at
|
|
|
|
|
1kHz. It would be extremely unusual to have a vibration mode with
|
|
|
|
|
aliasing at both frequencies at once, which means that all we needed
|
|
|
|
|
to do was work out which accelerometer is accurate at any point in
|
|
|
|
|
time. For the DCM code that involved matching each accelerometer at
|
|
|
|
|
each time step to the combination of the GPS velocity vector and
|
|
|
|
|
current attitude, and for the EKF it was a matter of producing a
|
|
|
|
|
weighting for the two accelerometers based on the covariance matrix.
|
|
|
|
|
|
|
|
|
|
The result is that the plane flew perfectly with the new dual
|
|
|
|
|
accelerometer code, automatically switching between accelerometers as
|
|
|
|
|
aliasing occurred.
|
|
|
|
|
|
|
|
|
|
Since adding that code I have been on the lookout for signs of
|
|
|
|
|
aliasing in other logs that people send me, and it looks like it is
|
|
|
|
|
more common than we expected. It is rarely so dramatic as seen on my
|
|
|
|
|
BigStik, but often results in some pitch error in turns. I am hopeful
|
|
|
|
|
that with a Pixhawk and the 3.0 release of APM:Plane that these types
|
|
|
|
|
of problems will now be greatly reduced.
|
|
|
|
|
|
|
|
|
|
For the dual gyro support we went with a much simpler solution and
|
|
|
|
|
just average the two gyros when both are healthy. That reduces noise,
|
|
|
|
|
and works well, but doesn't produce the dramatic improvements that the
|
|
|
|
|
dual accelerometer code resulted in.
|
|
|
|
|
|
|
|
|
|
Dual GPS was also quite a large development effort. We now support
|
|
|
|
|
connecting a 2nd GPS to the serial4/5 port on the Pixhawk. This allows
|
|
|
|
|
you to protect against GPS glitches, and has also allowed us to get a
|
|
|
|
|
lot of logs showing that even with two identical GPS modules it is
|
|
|
|
|
quite common for one of the GPS modules to get a significant error
|
|
|
|
|
during a flight. The new code currently switches between the two GPS
|
|
|
|
|
modules based on the lock status and number of satellites, but we are
|
|
|
|
|
working on a more sophisticated switching mechanism.
|
|
|
|
|
|
|
|
|
|
Supporting dual GPS has also made it easier to test new GPS
|
|
|
|
|
modules. This has enabled us to do more direct comparisons between the
|
|
|
|
|
Lea6 and the Neo7 for example, and found the Neo7 performs very
|
|
|
|
|
well. It also helps with developing completely new GPS drivers, such
|
|
|
|
|
as the Piksi driver (see notes below).

New AP_Mission library
|
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
|
|
Many months ago Brandon Jones re-worked our mission handling code to
|
|
|
|
|
be a library, making it much cleaner and fixing a number of long term
|
|
|
|
|
annoyances with the behaviour. For this release Randy built upon the
|
|
|
|
|
work that Brandon did and created the new AP_Mission library.
|
|
|
|
|
|
|
|
|
|
The main feature of this library from the point of view of the
|
|
|
|
|
developers is that it has a much cleaner interface, but it also has
|
|
|
|
|
some new user-visible features. The one that many users will be glad
|
|
|
|
|
to hear is that it no longer needs a "dummy waypoint" after a
|
|
|
|
|
jump. That was always an annoyance when creating complex missions.
|
|
|
|
|
|
|
|
|
|
The real advantage of AP_Mission will come in future releases though,
|
|
|
|
|
as it has the ability to look ahead in the mission to see what is
|
|
|
|
|
coming, allowing for more sophisticated navigation. The copter code
|
|
|
|
|
already takes advantage of this with the new spline waypoint feature,
|
|
|
|
|
and we expect to take similar advantage of this in APM:Plane in future
|
|
|
|
|
releases.

|
New Piksi GPS driver
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
One of the most exciting things to happen in the world of GPS modules
|
|
|
|
|
in the last couple of years is the announcement by SwiftNav that they
|
|
|
|
|
would be producing a RTK capable GPS module called the Piksi at a
|
|
|
|
|
price that (while certainly expensive!) is within reach of more
|
2014-04-07 20:49:25 -03:00
|
|
|
dedicated hobbyists. It offers the possibility of decimeter and
|
|
|
|
|
possibly even centimetre level relative positioning, which has a lot
|
2014-04-07 20:46:30 -03:00
|
|
|
of potential for small aircraft, particularly for landing control and
|
|
|
|
|
more precise aerial mapping.
|
|
|
|
|
|
|
|
|
|
This release of APM:Plane has the first driver for the Piksi. The new
|
|
|
|
|
driver is written by Niels Joubert, and he has done a great job. It is
|
|
|
|
|
only a start though, as this is a single point positioning driver. It
|
|
|
|
|
will allow you to use your new Piksi if you were part of the
|
|
|
|
|
kickstarter, but it doesn't yet let you use it in RTK mode. Niels and
|
|
|
|
|
the SwiftNav team are working on a full RTK driver which we hope will
|
|
|
|
|
be in the next release.
|
|
|
|
|
|
|
|
|
|
Support for more RC channels
|
|
|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
This release is the first to allow use of more than 8 RC input
|
|
|
|
|
channels. We now support up to 18 input channels on SBus on Pixhawk,
|
|
|
|
|
with up to 14 of them able to be assigned to functions using the
|
|
|
|
|
RCn_FUNCTION settings. For my own flying I now use a FrSky Taranis
|
|
|
|
|
with X8R and X6R receivers and they work very nicely. Many thanks to
|
|
|
|
|
the PX4 team, and especially to Holger and Lorenz for their great work
|
|
|
|
|
on improving the SBus code.
|
|
|
|
|
|
|
|
|
|
Flaperon Support
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
This release is the first to have integrated flaperon support, and
|
|
|
|
|
also includes much improved flaps support in general. You can now set
|
|
|
|
|
a FLAP_IN_CHANNEL parameter to give an RC channel for manual flap
|
|
|
|
|
control, and setup a FLAPERON_OUTPUT to allow you to setup your
|
|
|
|
|
ailerons for both manual and automatic flaperon control.
|
|
|
|
|
|
|
|
|
|
We don't yet have a full wiki page on setting up flaperons, but you
|
|
|
|
|
can read about the parameters here:

Geofence improvements
|
|
|
|
|
---------------------
|
|
|
|
|
|
|
|
|
|
Michael Day has made an number of significant improvements to the
|
|
|
|
|
geo-fencing support for this release. It is now possible to
|
|
|
|
|
enable/disable the geofence via MAVLink, allowing ground stations to
|
|
|
|
|
control the fence.
|
|
|
|
|
|
|
|
|
|
There are also three new fence control parameters. One is
|
|
|
|
|
FENCE_RET_RALLY which when enabled tells APM to fly back to the
|
|
|
|
|
closest rally point on a fence breach, instead of flying to the center
|
|
|
|
|
of the fence area. That can be very useful for more precise control of
|
|
|
|
|
fence breach handling.
|
|
|
|
|
|
|
|
|
|
The second new parameter is FENCE_AUTOENABLE, which allows you to
|
|
|
|
|
automatically enable a geofence on takeoff, and disable when doing an
|
|
|
|
|
automatic landing. That is very useful for fully automated missions.
|
|
|
|
|
|
|
|
|
|
The third new geofence parameter is FENCE_RETALT, which allows you to
|
|
|
|
|
specify a return altitude on fence breach. This can be used to
|
|
|
|
|
override the default (half way between min and max fence altitude).
|
|
|
|
|
|
|
|
|
|
Automatic Landing improvements
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
Michael has also been busy on the automatic landing code, with
|
|
|
|
|
improvements to the TECS speed/height control when landing and new
|
|
|
|
|
TECS_LAND_ARSPD and TECS_LAND_THR parameters to control airspeed and
|
|
|
|
|
throttle when landing. This is much simpler to setup than
|
|
|
|
|
DO_CHANGE_SPEED commands in a mission.
|
|
|
|
|
|
|
|
|
|
Michael is also working on automatic path planning for landing, based
|
|
|
|
|
on the rally points code. We hope that will get into a release soon.
|
|
|
|
|
|
|
|
|
|
Detailed Pixhawk Power Logging
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
One of the most common causes of issues with autopilots is power
|
|
|
|
|
handling, with poor power supplies leading to brownouts or sensor
|
|
|
|
|
malfunction. For this release we have enabled detailed logging of the
|
|
|
|
|
information available from the on-board power management system of the
|
|
|
|
|
Pixhawk, allowing us to log the status of 3 different power sources
|
|
|
|
|
(brick input, servo rail and USB) and log the voltage level of the
|
|
|
|
|
servo rail separately from the 5v peripheral rail on the FMU.
|
|
|
|
|
|
|
|
|
|
This new logging should make it much easier for us to diagnose power
|
|
|
|
|
issues that users may run into.
|
|
|
|
|
|
|
|
|
|
New SERIAL_CONTROL protocol
|
|
|
|
|
---------------------------
|
|
|
|
|
|
|
|
|
|
This release adds a new SERIAL_CONTROL MAVLink message which makes it
|
|
|
|
|
possible to remotely control a serial port on a Pixhawk from a ground
|
|
|
|
|
station. This makes it possible to do things like upgrade the firmware
|
|
|
|
|
on a 3DR radio without removing it from an aircraft, and will also
|
|
|
|
|
make it possible to attach to and control a GPS without removing it
|
|
|
|
|
from the plane.
|
|
|
|
|
|
|
|
|
|
There is still work to be done in the ground station code to take full
|
|
|
|
|
advantage of this new feature and we hope to provide documentation
|
|
|
|
|
soon on how to use u-Blox uCenter to talk to and configure a GPS in an
|
|
|
|
|
aircraft and to offer an easy 3DR radio upgrade button via the Pixhawk
|
|
|
|
|
USB port.
|
|
|
|
|
|
|
|
|
|

I hope that everyone enjoys flying this new APM:Plane release as much
|
|
|
|
|
as we enjoyed producing it! It is a major milestone in the development
|
|
|
|
|
of the fixed wing code for APM, and I think puts us in a great
|
|
|
|
|
position for future development.
