Amilcar Lucas fbc25e4baa AP_Mount: move mount to a "retracted position" into the fuselage with a fourth servo 2012-08-06 01:27:29 +02:00
Amilcar Lucas 36bcd827b4 AP_Mount: Allow using any RC channel to control any of the mount axes.
This has the added benefit of saving 60 bytes and simplifying Mission Planner gui.
Moved some code from RC_Channel_aux to AP_Mount class
The servos get written by the update_mount_position() function, this simplifies main()
PS: The beauty of using libraries: I did not have to touch a single line of ArduPlane's code!
2012-08-05 23:48:57 +02:00
Amilcar Lucas fe4713b46e RC_Channel: Allow each channel to know who they are, this simplifies the enabling and output function calls. 2012-08-05 23:08:31 +02:00

Robert Lefebvre 54b320a9a0 Fixing Trad Heli Ext ESC Controller
-Added ramp-down rate instead of instantly setting ramp to zero when throttle is dropped to bottom. This is to allow "warm-restart" if shutdown was unintentional.
-Actual ESC still goes to zero while throttle is dropped to the bottom, only the ramp counter winds down slowly behind the scenes.

rmackay9 23a1e33e20 AP_InertialSensor_MPU6000: another attempt at fixing the SITL build 2012-07-28 17:19:19 +09:00
rmackay9 06a4aaa763 AP_InertialSensor_MPU6000: changed DMP memory definition (dmpMem) to const uint8_t to remove SITL compile errors (hopefully)

rmackay9 5a9211c278 AP_AHRS: removed var_info from AP_AHRS class (moved to AP_AHRS_DCM) 2012-07-28 14:16:56 +09:00
rmackay9 c2b47d2bf9 AP_AHRS_DCM: moved var_info to belong to AP_AHRS_DCM instead of AP_AHRS 2012-07-28 14:16:15 +09:00

we are now 1.0 only
2012-07-26 10:03:36 +10:00
rmackay9 960c2f08af AP_Mount: addition of Amilcar's mount_type
set_roi_cmd modified to take a Location.  I know the intention was for set_roi_cmd to interpret the MAVLink command directly but unfortunately in arduCopter missions are only made up of waypoints (which are Locations).

Jonathan Challinger 21f0ed00b3 AHRS: normalise GA_b before computing error vector only if too large
When GA_b is small the direction of the vector is unreliable, so
normalising can exacerbate the error in the direction
2012-07-23 17:16:50 +10:00
Andrew Tridgell 99410cbbfe AP_AnalogSource: fixed reporting of VCC
the VCC pin number should not be converted

Andrew Tridgell 5f5c884a6d AHRS: if we don't have gps correction enabled, zero the yaw correction 2012-07-20 17:21:04 +10:00
Andrew Tridgell 4f41b876b1 AHRS: allow the gps/accelerometers to control yaw when rolled
this solves a problem with yaw estimation when at high roll angles,
when the compass code becomes ineffective
2012-07-20 11:50:04 +10:00
Andrew Tridgell 404803a734 MAVLink: imported updated generated mavlink C code

Amilcar Lucas 13fb2e6dc9 RC_Channel parameters: Fix a typo 2012-07-18 22:39:49 +02:00
Amilcar Lucas dea5b88379 Support up to 7 aux servo outputs 2012-07-18 21:58:22 +02:00
rmackay9 a2e6af1f9c AP_Mount: added set_manual_rc_channel and set_manual_rc_channel_function to allow input of pitch, roll and yaw controls from a regular RC_Channel (i.e. not RC_Channel_aux)
For now, angles red in are always of the range -45 deg ~ 45 deg which is consistent with the existing arducopter implementation but should be improved to scale the pilot's input to the mount's actual range.

Amilcar Lucas 23f009f665 Improve parameter documentation, it still does not work, but is an improvement.
I just do not understand why these parameters do not appear in Mission planner :(
2012-07-17 23:32:30 +02:00
Michael Oborne b97f9bb803 Airspeed Library - fix param names.
The Group definition give the start of the param name.
This way we can maintain multiple instances if required of the same library as options.
2012-07-16 21:48:47 +08:00
Andrew Tridgell dfb22554aa Airspeed: Added AP_Airspeed sensor library
this will allow an airspeed sensor object to be passed to AHRS for
dead reckoning
2012-07-16 11:21:20 +10:00
rmackay9 bec5321b8b AP_MotorsMatrix: small bug fix to limit checking on remove_motor call. Fix thanks to Michael Peschel! 2012-07-16 00:38:58 +09:00
rmackay9 3b9a1d4305 RC_Channel_aux: added enable_out method to help stop servos from moving before the mount has initialised.
changed parameter names of "update_aux_servo_function" to make it more clear that any 4 servos can be passed in (not just servos 5~8).
Also allowed NULL servos to be passed in as parameters because we only need 3 in ArduCopter.
2012-07-15 16:28:53 +09:00
rmackay9 e83275d8ae AP_Camera: changed "int" to "int16_t" and "long" to "int32_t" here and there. 2012-07-15 16:26:12 +09:00
Andreas M. Antonopoulos 31fd74d94c AP_Limits library, provides modular "limits" such as altitude and geo-fencing. 2012-07-14 19:26:17 -07:00

Robert Lefebvre 716ce6a5a7 Change to prevent Tricopter servos from going hard-over during Disarmed state.
Believe this was an oversight when the change to AP_Motors went in.
2012-07-13 23:12:26 -04:00
Robert Lefebvre ab1212d8d2 Instituting Yaw Differential on Multirotors. Intent is to stop "rise on yaw input".
Since motors with increasing speed due to yaw input seem to generate more thrust that motors that slow lose thrust, thus net thrust goes up, causing copter to climb.
Values are a guesstimate, proven out by test flying.  This could probably become a parameter.
2012-07-13 22:59:28 -04:00
Andreas M. Antonopoulos 9dfb3c4db9 Added Michael Pursifull's Maxsonar HRLV model support 2012-07-11 18:46:47 -07:00

rmackay9 1105a35c77 AP_AnalogSource_Arduino: fix to allow analog port to be read to be specified as a "channel" (i.e. A0)
Also fixed example range finder sketch to work with interrupt enabled AP_AnalogSource_Arduino class

Andrew Tridgell 2bc530d04f AP_Param: added some docs on the eeprom header format 2012-07-10 14:03:49 +10:00
Craig Elder 0534ac12b1 DataFlash: The current method for checking if chip erase worked is producing false positives. We are forcing the block erase until we have a deterministic test method. 2012-07-09 15:23:35 -07:00

Andrew Tridgell 7bc724d118 APM: changed PID library to do automatic deltat calculation
this fixes a problem with the HDNG2RLL PID, which was using the wrong
time base and prevents similar bugs from happening in the future
2012-07-06 19:59:18 +10:00
Andrew Tridgell 44755bf3ce AP_Baro: improved barometer averaging
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.
2012-07-06 15:11:30 +10:00
Andrew Tridgell 43d6015811 Filter: split the DerivativeFilter steps into update() and slope()
this allows us to apply new data at a different rate than we calculate
the slope.
2012-07-06 15:11:30 +10:00
Andrew Tridgell 4723698489 AP_Baro: update MS5611 test to use baro library altitude 2012-07-06 15:11:30 +10:00
Andrew Tridgell 9845a55cb1 AHRS: make the yaw independent drift correction optional and disable
the new correction algorithm copes poorly with gyro drift, leading to
signification attitude errors in the face of drift
2012-07-06 15:11:30 +10:00
Andrew Tridgell e33554a1f9 AHRS: only enable barometer for AHRS if it is smooth enough
if we used less than 5 samples to compute the pressure then don't use
it for climb rate
2012-07-05 16:29:21 +10:00
Andrew Tridgell 1ce4a03147 SITL: lower baro noise a bit 2012-07-05 16:29:21 +10:00

Andrew Tridgell 735c88e9b3 AP_Baro: added get_pressure_samples() interface
this returns how many samples were used to calculate the last pressure
2012-07-05 16:29:21 +10:00
Andrew Tridgell 92001e3e7d Filter: fixed typo in 9 point DerivativeFilter 2012-07-05 16:29:20 +10:00
Andrew Tridgell 999a1d1d55 AP_Baro: change to a 7 point DerivativeFilter for climb rate 2012-07-05 13:00:47 +10:00
Andrew Tridgell a07e280eda Filter: cope with non-uniform time steps in the DerivativeFilter
this helps with the barometer a lot, as the timing is quite variable
2012-07-05 13:00:47 +10:00
Andrew Tridgell ce3f8be6c7 SITL: add some minimal noise when motors are off
this actually improves the gyro calibration
2012-07-05 13:00:46 +10:00
Andrew Tridgell fe54329de2 MAVLink: remove MAVLink 0.9 protocol support
this simplifies the code a lot. We're not going back to 1.0
2012-07-05 13:00:46 +10:00
Andrew Tridgell 9d7ed30023 AHRS: only use GPS for yaw when compass is not being used
this avoids having two competing controllers
2012-07-05 13:00:46 +10:00
Andrew Tridgell 6653c0b874 AHRS: enable barometer for vertical velocity
this re-enables the barometer for vertical velocity information
for drift correction, now that we have a better filter
on the climb rate
2012-07-05 13:00:46 +10:00
Andrew Tridgell a5d607d25a AP_Baro: use DerivativeFilter in barometer climb rate 2012-07-05 13:00:46 +10:00
Andrew Tridgell f97289792b Filter: added DerivativeFilter implementation
this adds a DerivativeFilter implementation of up to 10 points
2012-07-05 13:00:46 +10:00
Andrew Tridgell cf2c546051 AP_Baro: show climb rate in baro test sketch 2012-07-05 13:00:45 +10:00

Andrew Tridgell dc6d70bc15 SITL: added SIM_GPS_DELAY parameter
this allows a delay to be added to the gps data to test the impact on
AHRS/DCM
2012-07-04 21:05:22 +10:00
rmackay9 cac0757c2e AP_AHRS: removed DCM_test example sketch
No longer required because it doesn't compile and is redundant anyway because the AP_AHRS_DCM class is tested in the AHRS_Test example sketch.
2012-07-04 18:22:51 +09:00
Andrew Tridgell 03516b7dfa AHRS: make DCM drift correction not rely on accurate yaw
this uses a new formulation of the GPS based drift correction from
Bill Premerlani that rotates the error vector to avoid relying on
accurate yaw. This means we should get accurate roll/pitch correction
even with lots of magnetometer interference

It also makes it possible to fly a multicopter with no compass. It can
even navigate and correct yaw (slowly!)
2012-07-04 17:00:40 +10:00
Andrew Tridgell 6cf2e2fa13 AP_Math: cope with co-located waypoints in location_passed_point() 2012-07-04 14:24:04 +10:00

Andrew Tridgell c6ff292721 DataFlash: fallback to BlockErase if ChipErase fails
The errata on the APM2 dataflash chip says that ChipErase may not work
on some chips
2012-07-04 12:42:46 +10:00
Andrew Tridgell 84a489498d Math: added location functions to math library
these do common calculations on struct Location
2012-07-04 12:42:46 +10:00
Andrew Tridgell e0685f4408 AHRS: make P gain on PI roll/pitch controller tunable
this is to make it easier for Craig and Alan to tune

Andrew Tridgell 1142ec0665 AP_Mount: removed unused enum 2012-07-03 10:39:34 +10:00
Andrew Tridgell f150c645c8 Mount: enable mount control via eeprom parameters
this enables MNT_* parameter control of the camera mount code. It also
fixes the conversion of calculated angles between degrees and
integers, and fixes stabilised mount control when yaw control is not
available.
2012-07-03 10:21:01 +10:00
Andrew Tridgell 7a77832f45 Baro: average over all pressure/temperature samples on MS5611
this allows us to use the MS5611 barometer at its full 100Hz sample
rate (80Hz for pressure, 20Hz for temperature). The pressure and
temperature values are averaged between reads without adding any
latency. Previously the driver would throw away values between
readings

This also fixes a race condition in reading from the SPI bus that
could lead to bad values from the barometer
2012-07-02 13:44:53 +10:00
Andrew Tridgell f7b06e0a64 Baro: fixed build of MS5611 test code 2012-07-02 13:44:53 +10:00

Andrew Tridgell 0341e0e5f0 SITL: added support for new analog source
removed analogRead() to prevent people using it
2012-07-01 15:01:05 +10:00
Andrew Tridgell 2046e396a2 AnalogSource: make the Arduino AnalogSource interrupt driven
this fixes several problems with reading analog sources:

 - we were getting poor values because we didn't wait long enough for
   an analog source to settle

 - we wasted a lot of CPU cycles waiting for conversions

 - we were not taking averages over many samples, which we did with
   the old AP_ADC driver on the APM1
2012-07-01 15:01:05 +10:00
Andrew Tridgell b5aa821071 AHRS: include the P terms in get_gyro()

Andrew Tridgell 117bae9585 SITL: added SITL class for controlling simulation
this holds mavlink settable parameters for controlling sensor noise
levels
2012-06-29 15:10:51 +10:00
Andrew Tridgell 37494dda2b AHRS: don't add the P terms in _omega
this can lead feedback via the _P_gain()
2012-06-29 15:10:51 +10:00
Andrew Tridgell 21ae2957fb AHRS: disable barometer for vertical acceleration
this seems to have been the cause of the 'flips' seen by Marco and
others. Testing by Craig and Alan shows that the flips are gone when
the barometric acceleration is removed.

It looks like a 5 point average filter is not enough to keep the
vertical acceleteration noise low. With high noise in the z axes, the
x and y axes are scaled back when the ge vector is normalised.

Andrew Tridgell e531061caa AHRS: re-instate new DCM drift correction code
This reverts commit 078489638d47fbaffde7c51249e36b5a8fc4ef9d.
2012-06-28 11:09:22 +10:00
Andrew Tridgell 8600ad8d7f AHRS: revert to the old drift correction algorithm

Andrew Tridgell ce016b5ae8 AHRS: include P term in omega
thanks to Jon for suggesting this
2012-06-27 16:01:50 +10:00
Andrew Tridgell 0fa1f29cf3 AHRS: implement spin rate limits
this follows the method that Bill developed in his fastRotations
paper. We've demonstrated that this is indeed needed in APM, as we
were able to produce the 'dizzy' effects in both the ArduPlane and
ArduCopter simulator
2012-06-27 16:01:50 +10:00
Andrew Tridgell 3ffecc18d8 AHRS: cope with copters with no compass
if a copter doesn't have a compass, we can't use the GPS for gyro

longitude scale does not apply to velocity->heading conversions
2012-06-27 16:01:50 +10:00
Andrew Tridgell 20c1baf585 SITL: changes UBlox simulation to 5Hz
this matches the real UBlox driver
2012-06-27 16:01:50 +10:00
Andrew Tridgell d9583ae5eb Compass: remove the need to call calculate() on the compass object
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.
2012-06-27 16:01:50 +10:00
Andrew Tridgell 5370f9c411 AHRS: normalize the ge vector in drift correction, and use barometer
The normalisation ensures the error term scales uniformly with
different accelerations.

The barometer is used for vertical acceleration estimation
2012-06-27 16:01:50 +10:00
Andrew Tridgell 53e950531e Baro: added get_altitude() and get_climb_rate() interfaces
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity

The climb rate uses a 5 point average filter
2012-06-27 16:01:50 +10:00
Andrew Tridgell 9fd3d15026 Filter: added 5 point average float filter 2012-06-27 16:01:50 +10:00
Jonathan Challinger 1ff9461bfb AHRS: brought DCM more inline with Bill's implementation
omega_I applied continuously. _ki larger. Stop integrating when _omega.length()>20

The key change was the scaling of ge to ensure the error is not
quadratic
2012-06-27 16:01:49 +10:00
Andrew Tridgell 73faaddc1b AHRS: first successful version of Bills new drift correction system
This makes 3 major changes:

 1) fixes the scaling of the yaw drift correction term to fix the time
 constant

 2) don't integrate the mag vector over multiple readings

 3) accumulate omega_I changes over 15 seconds before applying, to try
 to prevent omega_I picking up short term responses

Andrew Tridgell ae9883a8e2 GPS: fixed auto-config of UBlox setup with no UBX messages
if a UBlox is configured for NMEA only, with no UBX messages at all
then it would never trigger the GPS_AUTO detection. This adds a UBX
config message to the init strings that enables the NAV_SOL message
2012-06-15 15:53:27 +10:00
Andrew Tridgell b7e807cd58 FastSerial: added tx_pending() method
this allows the caller to wait for the tx buffer to drain

2012-06-10 16:34:13 +10:00
Andrew Tridgell 04a71197f9 FastSerial: avoid buffer re-allocation on re-open if possible
we commonly re-open serial ports a lot in the AUTO GPS driver
2012-06-09 07:43:22 +10:00
Andrew Tridgell f347572fc2 SITL: map() is a C++ function, so needs to be in C++ part of the header

Andrew Tridgell f4718cafad GPS: re-open the serial port with a 256 byte serial receive buffer
this ensures all GPS parsers have a 256 byte buffer available
2012-06-08 16:42:03 +10:00
Andrew Tridgell ddebf7b443 GPS: fixed the UBLOX parser to handle unknown messages
the parser was broken in several ways:

 1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
    thought the message had a bad checksum, which meant it got out of protocol sync

 2) the read() method would return false if the last message from the GPS was of an unknown type. 
    So we relied on the last msg always being one that we understand and want

 3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get 
    a new fix when we get box a new position and velned message

 4) the total message size per update is more than 128 bytes, but the serial port was opened 
    with only a 128 byte buffer, so we got corruption regularly

Andrew Tridgell c2fb8a7a98 DataFlash: use ChipErase() instead of PageErase() on all pages
This makes the DataFlash erase much faster (about 6 seconds instead of

2012-05-22 19:29:02 -07:00
Andrew Tridgell 8f27297896 DCM: fixed a bug when using GPS for yaw correction
When using GPS for yaw correction we need to apply the x and y omegaI
corrections from the _omega_I_sum in the period before we get to the
minimum ground speed for GPS yaw correction. Otherwise we get a large
sudden omega_I change on takeoff.

mechanisms available via waypoints
2012-04-24 10:57:43 +10:00
Andrew Tridgell 6d837891b0 DCM: buffer omega_I changes over 10 seconds
this buffers up _omega_I changes in _omega_I_sum over a period of 10
seconds, applying the slope limit only when _omega_I_sum is
transferred to _omega_I.

The result is a huge improvement in the ability of _omega_I to track
gyro drift over the long term.
2012-04-23 12:13:25 +10:00
Andrew Tridgell 398a608b83 DCM: drop the 'drop z' method
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

  http://diydrones.com/xn/detail/705844:Comment:834373

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.

rmackay9 71ad185238 ArduCopter - AP_Motors library - added new library which has few advantages over current code:
1. it's step towards rearchitecting the current code base ahead of a move to RTOS.
     2. internally it uses a MatrixTable for the Quad, Octa, OctaQuad, Y6 frames.
     3. it implements the missing stability patch for Octa and OctaQuads (still missing for Y6)

Later check-ins will incorporate into the main ArduCopter code.

Andrew Tridgell 08b66e18b7 FastSerial: added set_blocking_writes() interface
this allows us to put a serial port into non-blocking mode, so that
writes that don't fit in the transmit buffer are dropped. This will be
used in flight to prevent stray printf() calls from causing large time
delays in the code
2012-03-30 17:46:20 +11:00
Andrew Tridgell c2ff66c9cd examples: fixed build of some examples with new AP_Declination code 2012-03-30 14:25:27 +11:00
Andrew Tridgell 825340d53d Compass: added COMPASS_AUTODEC option
when this is 1 (which is the default), we will get the declination
automatically via the AP_Declination library

when it is 0 we will use the value configured by the user
2012-03-30 14:25:27 +11:00
Andrew Tridgell e4e052ff91 AP_Declination: save some more memory by putting the declination keys in progmem
there was a comment saying this was too slow, but it actually costs
about 30 usec extra, which is trivial given the full auto declination
call costs 680 usec and its only called once per boot
2012-03-30 14:25:27 +11:00
Andrew Tridgell edb627a5c1 AP_Declination: added timing information to declination test 2012-03-30 14:25:27 +11:00

Adam M Rivera 9c414e9573 AP_Declination_test: Updated test with better print messages. 2012-03-30 14:25:26 +11:00
Adam M Rivera cff189e911 AP_Declination: Update LUT based on the changes that I made in the LUT generation code. This LUT is the final version that has no truncation. 2012-03-30 14:25:26 +11:00
Adam M Rivera 380b9ece44 AP_Declination: Updated comments to reflect new LUT size. 2012-03-30 14:25:06 +11:00
Adam M Rivera c04e074c89 AP_Declination: Removed trailing zero deltas as they have no impact on the final value and only take up extra bytes. 2012-03-30 14:21:58 +11:00
Adam M Rivera 662f11f801 AP_Declination: Updated compressed lookup value table. Located 9 more failure points due to truncation on the packed LUT. 2012-03-30 14:21:58 +11:00
Adam M Rivera 0178906389 AP_Declination: Found 7 of the 22 failure points and fixed them. The issue with those 7 was the way I originally packed the value array. The last delta values on some rows were getting truncated. The new number of failures is down to 15 - WIP. 2012-03-30 14:21:58 +11:00
Adam M Rivera 08259bb2de AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail. 2012-03-30 14:21:58 +11:00
Adam M Rivera 64c236800c AP_Declination: Moved check for y index of zero to after the y index is properly transformed. 2012-03-30 14:21:58 +11:00
Adam M Rivera e99d26cfa3 AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left. My packed signs byte was packed left to right (left most being the 0 position) so I needed to reverse the shifting. 2012-03-30 14:21:58 +11:00
Adam M Rivera d9c9e0e608 AP_Declination: In order for the bitwise & operation to work, negative signs need to be represented by 1s instead of 0s. Changed so that negative signs are represented by a 1 in the packed signs array. Updated lookup logic to reflect this change. 2012-03-30 14:21:58 +11:00
Adam M Rivera 8b1c383f97 AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly. 2012-03-30 14:21:57 +11:00
Adam M Rivera c0813f8d62 AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular. 2012-03-30 14:21:57 +11:00
Adam M Rivera 289d7a2784 AP_Declination: Added original array to test sketch. Added loop to validate new compressed array against original in 1 degree steps. 2012-03-30 14:21:57 +11:00
Adam M Rivera 63ce400f77 AP_Declination: Moved rows with large spikes in delta to their own unsigned exception rows. The signs are in a separate packed array. 2012-03-30 14:21:57 +11:00
Adam M Rivera 782c1aaaa3 AP_Declination: Implemented Delta Encoding and Run-Length Encoding. Added method to traverse the compressed array and return the lookup value based on the same lat_index/lon_index that was used before. 2012-03-30 14:21:57 +11:00
Adam M Rivera 9888a4730f AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype. 2012-03-30 14:21:57 +11:00
Adam M Rivera d883bdf75e AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range. 2012-03-30 14:21:57 +11:00
Adam M Rivera 719636d00c AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t. 2012-03-30 14:21:57 +11:00
Andrew Tridgell 071f89df2e AHRS: fixed error_yaw reporting with 2 MAVLink connections
when a user first connects with USB, and later switches to the
telemetry port without restarting we were getting zero for error_yaw
in the logs, as AHRS.get_error_yaw() was being called twice.

This ensures we give the last value after the counter is reset

Andrew Tridgell 2a011578f9 Compass: implement noise resistant varient of offset learning
This adds a large amount of noise robustness to the compass offset
learning algorithm, at a cost of 120 bytes of memory. The changes are
based on a long discussion with Bill Premerlani.
2012-03-28 20:55:27 +11:00
Andrew Tridgell 16f094a1c5 ADC: minor fix to the ADC Ch6() code

2012-03-27 15:37:24 +11:00
Andrew Tridgell a3d3dd86cf Compass: implement Bills new offset nulling algorithm
this seems to work much better than the old algorithm, converging
faster and more accurately. Even better, it has no linkage to DCM, so
no possibility of nasty feedback effects
2012-03-27 15:37:24 +11:00
rmackay9 cf1a6f8ab8 APM_RC - moved Force_Out0_Out1, Force_Out2_Out3 and Force_Out6_Out6 to APM_RC parent class because it's already implemented in the APM1 and APM2 child classes anyway 2012-03-25 21:13:31 +09:00
rmackay9 2324be7e68 Filter - added simple LowPassFilter (simple but it's possible to make errors with simple stuff too so might as well have one) 2012-03-25 16:15:25 +09:00
rmackay9 bdda74fd28 Filter - remove obsolete warning from comments re alloc/malloc dangers 2012-03-25 16:14:07 +09:00

Andrew Tridgell fb9790e1f4 Math: moved matrix multiple operations to .cpp file
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space

We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space

rmackay9 f3eb15167c AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy)
- also removed unused _offset_press variable
2012-03-18 15:18:05 +09:00
rmackay9 ed0d1da4f5 AP_Baro - added average filter for temperature to replace broken filter

Andrew Tridgell 404a4e4896 ADC: use floats for ADC averaging
this costs almost nothing and improved accel/gyro calibration
2012-03-10 10:34:32 +11:00
Andrew Tridgell 4c6afa36cb DCM: removed update_DCM_fast
this combines the functionality of the 'fast' DCM with the normal one,
and also speeds up both the yaw drift correction and the matrix update
code

Andrew Tridgell a8fd31a5e1 AP_Math: added quaternion->matrix and earth frame routines
this will be used for 3d acceleration
2012-03-10 10:34:31 +11:00
Andrew Tridgell d3dc5bd751 AP_Math: better way of handling safe_sqrt()
better to test the result, than predict it

Andrew Tridgell 89a10c584d Quaternion: added more numerical safety in the quaternion code
prevent infinities from creeping in and prevent large drift changes
2012-03-10 10:34:30 +11:00
Andrew Tridgell f2e6714598 AP_Math: added quaternion helper functions and a test suite 2012-03-10 10:34:30 +11:00
Andrew Tridgell f71311fdc0 Quaternion: fix the gyro bias in centripetal and remove smoothing
the centripetal code needs to take account of the current gyro
bias.

It turned out that the accel and gyro smoothing was causing
significant control lag, and we're better off just letting the
quaternion code handle it via its own smoothing parameters
2012-03-10 10:34:30 +11:00
Andrew Tridgell 76736792f8 SITL: disable interrupts during register updates
this may prevent bogus mode channel reads
2012-03-10 10:34:30 +11:00
Andrew Tridgell e445a455d0 Quaternion: use GPS to correct for linear acceleration
this gives much better pitch estimates. We should do this with the
airspeed sensor if available.
2012-03-10 10:34:30 +11:00
Andrew Tridgell 1ea1b500a6 Quaternion: don't update if we have a very long deltat
this can be caused by stopping the system in a debugger

this should give a much more accurate result
2012-03-10 10:34:29 +11:00
Andrew Tridgell de1cfc8e34 Quaternion: drop the gyro drift rates down
this should allow us to cope with noise more readily

Andrew Tridgell fb23c617fa Quaternion: added an AP_Quaternion library
this is for experimenting with the Madgwick quaternion system, to see
if it is more or less noise sensitive than DCM
2012-03-10 10:34:28 +11:00
Andrew Tridgell a05eeab55e SITL: reduce the simulated compass offsets
this was causing us problems in getting DCM right
2012-03-10 10:34:28 +11:00
Andrew Tridgell d03b11092b SITL: separate out drift speed and drift level 2012-03-10 10:34:28 +11:00
Andrew Tridgell 71d3847bfc SITL: added a drift_level multiplier
this makes it easier to experiment with different gyro drift levels
2012-03-10 10:34:28 +11:00
Andrew Tridgell 61ebcfe9fe DCM: fixed the averaging of accel values for update_DCM_fast()
this should improve drift correction for ArduCopter
2012-03-10 10:34:28 +11:00
Andrew Tridgell de32c3bc31 AP_Math: added a .zero() method to Vector3f 2012-03-10 10:34:28 +11:00
Andrew Tridgell a0e2e69431 SITL: fixed delay() to account for signal interrupions
when a timer went off we stopped the delay() code
2012-03-10 10:34:28 +11:00
Andrew Tridgell 37ab76c9e6 DCM_Test: fixed example code to work with SITL
this also fixes the compass setup
2012-03-10 10:34:27 +11:00
Andrew Tridgell d2a969ee95 SITL: push noise level to 2.0 for DCM testing 2012-03-10 10:34:27 +11:00
Andrew Tridgell 79b8ddc236 DCM: added a small amount of accel smoothing to update_DCM_fast() 2012-03-10 10:34:27 +11:00
Andrew Tridgell 55413bfcc1 DCM: don't use the z accel sensor for drift correction
the z accel is the noisest, and seems to do more harm than good. Using
just x and y is sufficient for drift correction by assuming the vector
length
2012-03-10 10:34:27 +11:00
Andrew Tridgell a78b00513b DCM: added a small amount of gyro and accel smoothing
possibly not needed, but convenient to be able to test with different
values
2012-03-10 10:34:27 +11:00
Andrew Tridgell 82032b17a9 DCM: added reporting interfaces for DCM state 2012-03-10 10:34:27 +11:00
Andrew Tridgell ae6a94a933 SITL: added sitl_simstate_send()
used to report simulator state in logs
2012-03-10 10:34:27 +11:00
Andrew Tridgell d106e3a970 MAVLink: import new message types DCM, HWSTATUS and SIMSTATE 2012-03-10 10:34:27 +11:00
Andrew Tridgell 4e354a9731 DCM: got rid of _error_roll_pitch from object state
this can be a local error variable in common with the yaw code. This
saves 12 bytes in the object.
2012-03-10 10:34:27 +11:00
Jason Short 13e9608fb8 Consolidated Barometer pressure sensing to a single filter based on Randy's new filter class. 2012-03-08 23:13:04 -08:00
Jason Short 34cf1e8fb3 Updated on Barometer - increased the Temp filtering and decreased the pressure filtering to and get less temp noise, faster response from pressure. I'm filtering the Climb rate differently now, so this higher pressure noise should not hurt the derivative calcs at all now. 2012-03-06 20:55:35 -08:00
rmackay9 6c1299fe7e AP_RC - removed unused library 2012-03-04 18:21:52 +09:00
Andrew Tridgell dd9065123c SITL: use the new noise model
use the new noise model at a low level for master until we sort out
DCM noise handling
2012-03-02 18:31:07 +11:00
Andrew Tridgell 63ea5dfb49 APM_RC: allow the fast RC speed to be passed as a parameter
this will allow users to test different speeds
2012-03-02 17:57:08 +11:00
Andrew Tridgell f1a389fe19 AP_Param: ensure we can't have duplicate keys in Parameters.h
this is O(n^2), but only at startup, and takes less than 1ms to run.
It catches a very nasty coding error
2012-03-02 15:48:28 +11:00
Andrew Tridgell 1476f044e6 I2C: added lockup_count() interface
used for reporting I2C problems
2012-03-02 15:48:27 +11:00
Andrew Tridgell c9031f1d36 SITL: implement cli()/sei() properly for desktop build
this disables simulated hardware interrupts during critical sections

Pat Hickey 42078f2794 AP_Param: Make nested group recursion disableable by macro
* Eliminates recursive calls inside AP_Param.
  This is important to Pat @ Galois, but not the project in general.
  Recursion depth on these functions is bounded structurally using
  existing nested group constructors (can't create loops in finite space)
  and checked at init time
2012-02-28 16:28:27 -08:00
rmackay9 400a4b0bdb AP_RangeFinder - changed example sketch to work with new Filter library 2012-02-28 21:02:10 +09:00

rmackay9 d17a015df1 Filter - added AverageFilter, removed SumFilter
added FilterWithBuffer to allow removal of malloc/free without losing ability to pass around filter objects
2012-02-28 21:01:11 +09:00
Andrew Tridgell 078268528e AP_Param: show numerical value in eeprom dump utility 2012-02-28 09:43:49 +11:00
Andrew Tridgell 701da6c30f AP_Param: fixed v.load() on a sub-element of a AP_Vector3f
this isn't actually used at the moment in APM, but we should get it
right in case someone does try to load a single element of a vector
2012-02-28 09:43:49 +11:00
Andrew Tridgell 34f1ebcfb4 SITL: simulate noise on each ADC channel separately
scale the noise based on the period of the motors
2012-02-28 09:43:49 +11:00
Andrew Tridgell 4cdc0a8c11 SITL: raise the ADC noise level to 8 bits when flying
this is about the level of noise of a aircraft that has a lot of
vibration
2012-02-28 09:43:49 +11:00
Andrew Tridgell b32701e008 IMU: removed unused accel_filtered code 2012-02-28 09:43:49 +11:00
Andrew Tridgell ac44b73951 AP_Param: fixed setting of CAM_P_G in ArduCopter
the variable CAM_P_G has the same prefix as the CAM_P group. We want
to allow for parameters having a common prefix with a group, so we
need to keep searching after we've found a group that matches the
prefix
2012-02-27 10:54:33 +11:00
Andrew Tridgell 7fe4a41c31 AP_Param: make the templating code a bit clearer
add comments on the arguments, and name them in a clearer way
2012-02-27 10:54:33 +11:00
Andrew Tridgell 5bf138fb38 DCM: fixed the sense of the compass GPS test in initial yaw
we were only disabling null offsets when we didn't have a compass,
which doesn't make much sense!
2012-02-26 22:24:45 +11:00
rmackay9 747e045193 ModeFilter - corrected shadowed variable compiler warning for drop_high_sample 2012-02-26 17:57:28 +09:00
rmackay9 e01477a7a8 Filter - added AverageFilter - this will be used in place of SumFilter because it removes the possibility of overflows 2012-02-26 17:34:36 +09:00
rmackay9 b345529241 Filter - removed shadowing of variables in constructors for Filter, ModeFilter and SumFilter (sorry tridge!)
increased maximum sample buffer size from 6 to 10
2012-02-26 17:17:46 +09:00
rmackay9 3f0d27ec87 ModeFilter - remove older ModeFilter library (new library is now in Filter directory) 2012-02-26 15:36:23 +09:00

rmackay9 f6f05755d9 AP_Mount - #include FastSerial first to allow it to compile under Arduino 1.0 2012-02-26 15:31:56 +09:00
Andrew Tridgell bd2776aedd Compass: use constructor to set initial values for _learn and _use_for_yaw
this ensures they are set if you have MAG_ENABLE==0
2012-02-25 17:36:31 +11:00
Andrew Tridgell 56bb74ef36 DCM: disable compass null offsets when setting initial yaw
we need to ensure the compass null offsets code doesn't see a sudden
yaw change, or it will change the offsets by a large amount very
suddenly
2012-02-25 16:02:24 +11:00
Andrew Tridgell f50f4357ca Compass: catch the case of a user enabling a compass mid-flight
if a compass has not been initialised at startup we can't enable it
mid-flight, as we don't have the orientation
2012-02-25 14:51:09 +11:00
Andrew Tridgell 3abe035557 DCM: use the new use_for_yaw() compass method 2012-02-25 14:51:09 +11:00
Andrew Tridgell c3319afadd Compass: added COMPASS_LEARN and COMPASS_USE parameters
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1
2012-02-25 14:51:08 +11:00
Andrew Tridgell 051bd78b37 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 3cf0eebac8 DCM: don't reset _have_initial_yaw for GPS heading unless very slow
wait till we reach 1m/s before we reset _have_initial_yaw. This
prevents us continually resetting the DCM matrix if our ground speed
is close to 3m/s.
2012-02-25 11:37:20 +11:00
Andrew Tridgell 007a6b8958 AP_Param: added special handling for Vector3f
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality
2012-02-25 11:37:20 +11:00
Andrew Tridgell 1d95137b71 SITL: added -C option to desktop mode
this allows running APM to stdout, which is useful for test sketches
2012-02-25 11:37:20 +11:00
Andrew Tridgell f221bd13ab libs: removed unused library GPS_IMU 2012-02-25 11:37:20 +11:00
Andrew Tridgell 1a21c78062 libs: removed unusued library GCS_SIMPLE 2012-02-25 11:37:20 +11:00
Andrew Tridgell c63ca9c697 DCM: tidy up use of error_course and in_motion
in_motion is not a good name now it is also used for the compass

The error_course and heading component values don't need to be part of
the DCM object, they can be on the stack to reduce the memory usage a bit
2012-02-25 11:37:20 +11:00
Andrew Tridgell d5b619218c DCM: use rotation_matrix_from_euler() to calculate initial yaw
When we first get a compass reading or we first start motion we need
to setup the DCM matrix with the right yaw. This uses
rotation_matrix_from_euler() to get a DCM matrix corresponding to our
current roll/pitch, but with the correct yaw
2012-02-25 11:37:20 +11:00
Andrew Tridgell 48cad8bc25 DCM: use rotation_matrix_from_euler() in matrix reset
this makes the code a bit easier to read
2012-02-24 11:54:11 +11:00
Andrew Tridgell 5009679617 DCM: use calculate_euler_angles() to get eulers from DCM
this makes the code a bit easier to understand
2012-02-24 11:52:55 +11:00
Andrew Tridgell df6013616e AP_Math: added rotmat <-> euler functions
these will make the dcm matrix manipulation easier to understand
2012-02-24 11:52:55 +11:00
Andrew Tridgell 50f85835bd Compass: ensure we don't produce NAN values for compass heading
this leaves the previous heading values alone if we are at a pitch of
exactly 90 or -90, at which point we can't compute a meaningful
heading
2012-02-24 11:52:55 +11:00
Andrew Tridgell 8190204287 AP_Math: added safe_sqrt() function
this function will never return NAN. It will return zero for negative
numbers.
2012-02-24 11:52:55 +11:00
Andrew Tridgell 0acea11152 DCM: tidy up the nan checking in DCM
use is_nan() on the matrix rather than just on c.x, and add
safe_asin() to the (unused) OUTPUTMODE==2 code.
2012-02-24 11:52:55 +11:00
Andrew Tridgell b4c8d6491a DCM: added matrix recovery on reset
when we get a bad DCM error we can recover a matrix corresponding to
the current attitude, making it more likely that the aircraft will be
able to recover
2012-02-24 11:52:55 +11:00
Andrew Tridgell 1a32ececb4 AP_Math: added a safe_asin() function
this adds range checking to asin()
2012-02-24 11:52:55 +11:00
Andrew Tridgell 7dd909a16b AP_Math: added is_nan() methods to vector3f and matrix3f 2012-02-24 11:52:55 +11:00
Jason Short 2a4b7facaa added set integrator 2012-02-23 09:38:08 -08:00
Andrew Tridgell 8707965c15 DCM: changed the sense of floating point range comparison
This allows us to detect NaN, otherwise NaN values were considered 
'in range'
2012-02-23 11:41:26 +11:00
Andrew Tridgell 9caa4aeb44 DCM: range check the matrix before calculating pitch
The asin() in the pitch calculation can only take values between -1
and 1. This change ensures that the value is in range, and if it isn't
then we force a normalization. If that fails we reset the matrix
2012-02-23 08:16:08 +11:00
Andrew Tridgell 13693e1a04 DCM: reset more values on renorm blowup
when DCM blows up, we need to reset a lot more variables to ensure
that any NaN values don't persist
2012-02-23 08:16:08 +11:00
Andrew Tridgell 5cfe1ad5dc DCM: remove the taylor expansion optimisation for renormalisation
The sqrt() costs about 44usec on a 2560, which is small enough for us
not to worry about the speed.

This also changes the range of values where we declare a blowup to
much less likely, which means we can cope with larger delta_t glitches

justinbeech 5255512bf9 Found free extra 256 bytes of RAM eliminate _clz use from libgcc
Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment.

The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz
The _clz table gets pulled in if you do 64 bit division.
This tiny change is the only place that we do long long division.
Changing to a shift saves 256 bytes of ram.

Andrew Tridgell 7621b96a52 AP_Param: added group idx, and change packing of header elements
adding a idx element to the GroupInfo will make it less likely that a
developer will change the IDs of group elements, and make it easier to
see that these IDs are important for identifying a variable in EEPROM

The header packing has changed to make it 24 bits on all platforms,
which allows us to lower the EEPROM variable max size to 1024 bytes
again

Doug Weibel e109992c12 Add a CLI setup action to reset the magnetometer offsets
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

Andrew Tridgell f4490b62c7 DCM: prevent a segmentation fault when compass is not enabled

2012-01-13 15:48:07 +11:00
Doug Weibel 622217357c Bug fix for compass.
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.

Andrew Tridgell 089470a671 DataFlash: moved high level logging logic to library
this moves out all the high level logic from ArduPlane/ArduCopter to
the library. It also adds a "config page", as the last page in the
flash. This is used to check if the flash needs erasing. We only erase
now if the DF_LOGGING_FORMAT has changed.

This patch also adds a public CardInserted() method, which is used to
disable logging on APM2 if a dataflash card is not inserted

Andrew Tridgell 1cb8728a6b MPU6000: protect the driver from double initialisation
initialising twice can lockup the driver

Andrew Tridgell f2bbfb1296 MPU6000: minor fixes
the hardware functions should be private, and cs_pin should be uint8_t
2011-12-28 16:00:48 +11:00
Andrew Tridgell d35113f8a6 TimerProcess: check for duplicate registrations
if a driver gets initialised twice, make sure it doesn't get called
twice in the timer loop

Andrew Tridgell dd26ef3089 dataflash: reworked classes to move most code to parent class
this moves all the non-hardware specific code to the parent
DataFlash_Class class, keeping the hw specific code much smaller and
simpler.

This should prevent discrepancies creeping in between APM1 and APM2
support again

Andrew Tridgell 8bf05982ae dataflash: fixed APM2 flash logging
we had log wrap disabled on APM2, and also had the wrong log size. The
mainline code assumed 4096, but it is 8192 pages long.
