Author	SHA1	Message	Date
Andrew Tridgell	583845cc17	ahrs fixup	12 years ago
Andrew Tridgell	1b0670e67c	AHRS: fixup for ARM compiler	12 years ago
rmackay9	bd0e018ca0	ArduCopter: restore auto-trim method but now use AHRS.add_trim	12 years ago
rmackay9	1f7614929f	AP_AHRS: save trim to eeprom when set_trim is called	12 years ago
rmackay9	1c08f176ea	AP_AHRS: add get_accel_ef method to return earth frame accelerometer values for use in ArduCopter's inertial nav and accel based throttle	12 years ago
Andrew Tridgell	5c148153ac	AP_AHRS: updates for new AP_Param API	12 years ago
Pat Hickey	9bf69d4e0d	AP_AHRS: port to AP_HAL	12 years ago
Pat Hickey	3f1d9d7f69	AP_Param: #include <AP_Param.h> fixups for libraries & sketches ... * I mostly went through with grep and added an #include <AP_Param.h> below every #include <AP_Common.h>. Not all of these example sketches might strictly need AP_Param.	12 years ago
rmackay9	83ae8e47be	AP_AHRS: replace IMU with INS and add roll and pitch trim	12 years ago
rmackay9	8c6fd340d7	AP_AHRS: added scheduler parameter to init ... Required by the AP_AHRS_MPU6000 class which needs to disable timed processes that could interfere with it's communication with the mpu6000	13 years ago
Andrew Tridgell	fba1692d69	AHRS: added AHRS_BARO_USE parameter ... allow disabling of the use of the barometer for vertical acceleration compensation	13 years ago
Andrew Tridgell	de28cc8b28	AHRS: added AHRS_WIND_MAX option ... this allows APM to cope better with airspeed sensor failure, but ensuring airspeed stays within AHRS_WIND_MAX of ground speed	13 years ago
Andrew Tridgell	2be785899b	AHRS: added airspeed_estimate() function ... this allows the APM code to use an airspeed estimate for navigation	13 years ago
Andrew Tridgell	8b53f1272a	AHRS: new functions to support APM_Control library	13 years ago
uncrustify	af588679b9	uncrustify libraries/AP_AHRS/AP_AHRS.h	13 years ago
Andrew Tridgell	6d28b3519f	AHRS: removed AP_AHRS_Quaternion ... this AHRS backend is causing compiler errors with the Arduino build environment on windows. The quaternion AHRS backend is currently not being developed/supported anyway. We can resurrect it if someone wants to start developing it again.	13 years ago
Andrew Tridgell	134cd51d17	AHRS: moved var_info[] into top level AP_AHRS class	13 years ago
Andrew Tridgell	ac72db8f00	AHRS: added set_fast_gains() method ... this will be used by arducopter on the ground	13 years ago
Andrew Tridgell	9b4b7997b6	AHRS: added ahrs.yaw_initialised() ... this allows the high level code to know if the AHRS driver has a reliable yaw estimate	13 years ago
Andrew Tridgell	48e275e22d	AHRS: avoid a compiler bug in quaternion code ... Having _wind in the AP_AHRS class causes a register allocation error when building the Quaternion code with some versions of avr-gcc. Quite bizarre.	13 years ago
Andrew Tridgell	779dacfd24	AHRS: added wind estimation code ... this allows us to estimate the wind while we have GPS lock, then use that estimate in the long term dead reckoning	13 years ago
Andrew Tridgell	af4071894e	AHRS: added long-term dead-reckoning ... this uses airspeed (if available) or last GPS ground speed to update our position estimate in AHRS	13 years ago
Andrew Tridgell	f95b06a880	AHRS: make airspeed sensor available to AHRS ... this will be used for long term dead-reckoning	13 years ago
rmackay9	b844bb7919	AP_AHRS: removed var_info from AP_AHRS class (moved to AP_AHRS_DCM)	13 years ago
Andrew Tridgell	58c4d458dc	AHRS: re-instate new DCM drift correction code ... This reverts commit 078489638d47fbaffde7c51249e36b5a8fc4ef9d.	13 years ago
Andrew Tridgell	fd241692d0	AHRS: revert to the old drift correction algorithm ... we need to work out why Craigs quad flipped today before we enable this new drift correction	13 years ago
Andrew Tridgell	3a41ad8e7c	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	13 years ago
Andrew Tridgell	0f5c22bd8e	AHRS: implement Bills new drift correction algorithm ... this is an initial implementation of this paper: http://gentlenav.googlecode.com/files/RollPitchDriftCompensation.pdf	13 years ago
Andrew Tridgell	f27d85cb8d	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.	13 years ago
Andrew Tridgell	8e90aeea4e	AHRS: added AHRS_YAW_P parameter ... this allows users to change the yaw gain in DCM	13 years ago
rmackay9	c96dfb2108	AP_AHRS - changed parameter order to remove compiler warning	13 years ago
Andrew Tridgell	9e6c18cca4	AHRS: added missing AP_AHRS.h	13 years ago
