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.

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

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

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

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

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!

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

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 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
2012-02-23 08:16:08 +11:00
Andrew Tridgell f30c721886 AP_Param: added ParamToken type for variable list traversal 2012-02-19 17:05:28 +11:00
Jason Short 669e8e34ea added a limit to range output 2012-02-18 21:08:17 -08:00
Randy Mackay 0b369cf78b Optflow - added reference to FastSerial to resolve compile error on Arduino 1.0.
also removed reference to DCM (no longer required) and removed some old code.
2012-02-18 18:09:40 +09:00
Andrew Tridgell 2472f0a2f3 SITL: increase the amount of noise in the simulated ADC
this increases the noise to 2 bits, which actually can have the effect
of improving accuracy, as it leads to better averaging
2012-02-18 19:27:15 +11:00
Andrew Tridgell 9602b1f91b DCM: only add in centripetal accel if we have GPS lock
if we don't have a GPS or the GPS doesn't have a good lock then we
can't rely on the ground speed for adjusting the acceleration vector
2012-02-18 19:27:15 +11:00
Andrew Tridgell 371a91cfcf IMU: move _sensor_cal to general IMU class
this makes it available both in shim and INS subclasses
2012-02-18 10:51:57 +11:00
Andrew Tridgell 2b8f0c3a48 AP_Param: moved AP_Vector3f and AP_Matrix3f declarations to AP_Math.h

Andrew Tridgell 70a135c47c AP_Param: fixed copy-assignment operators for AP_Param vectors 2012-02-18 10:51:57 +11:00
Andrew Tridgell e656928c01 AP_Param: added a set_and_save_ifchanged() method
this can be used to avoid the scan() in more frequenctly saved
variables, such as the MAVLink stream rates in APM
2012-02-18 10:51:57 +11:00
Andrew Tridgell 6f080742b8 AP_Param: added an initialised() method
this will be used by the compass code
2012-02-18 10:51:57 +11:00
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.

Jason Short 560985b509 made I term return in same pattern as D term 2012-02-16 22:09:22 -08:00
Andrew Tridgell 3fbb5a2d6c ADC: on channel overflow we should not zero last_ch6_micros
this happens every 64 seconds because of unused channels on the
ADC. Zeroing this creates a bad delta_t value for the DCM code.
2012-02-16 17:48:36 +11:00

2012-02-15 08:50:45 +11:00
Andrew Tridgell c39914e734 DCM: added a SITL_debug() for DCM normalisation errors
I have seen normalisation errors during simulation runs, but have not
yet tracked down the cause. This log message may help track things
down.
2012-02-15 08:50:45 +11:00
Andrew Tridgell 7355f5613c added SITL_debug() macro
this can be used to print a message into the logs in the SITL
simulator. This will be used for critical conditions.

this means the 'show' command in the CLI shows the compass offsets now
2012-02-14 08:34:50 +11:00
Andrew Tridgell 4ec3857476 GPS: change back to 4Hz for MTK GPS
