Andrew Tridgell	f03ba86d9d	SITL: add some minimal noise when motors are off this actually improves the gyro calibration	13 years ago
Andrew Tridgell	60caaa4b04	MAVLink: remove MAVLink 0.9 protocol support this simplifies the code a lot. We're not going back to 1.0	13 years ago
Andrew Tridgell	2cd6da2539	AHRS: only use GPS for yaw when compass is not being used this avoids having two competing controllers	13 years ago
Andrew Tridgell	adfa97b6f8	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	13 years ago
Andrew Tridgell	f9fc7aafe7	AP_Baro: use DerivativeFilter in barometer climb rate	13 years ago
Andrew Tridgell	f19e5a6273	Filter: added DerivativeFilter implementation this adds a DerivativeFilter implementation of up to 10 points	13 years ago

Amilcar Lucas	0febf76d9d	Document++	13 years ago
Amilcar Lucas	e9c72822dc	Remove unused function	13 years ago
Andrew Tridgell	c35a2e999b	SITL: added SIM_GPS_DELAY parameter this allows a delay to be added to the gps data to test the impact on AHRS/DCM	13 years ago
rmackay9	faeda3713e	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.	13 years ago
Andrew Tridgell	3849ca8b5c	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!)	13 years ago
Andrew Tridgell	1cd8c54f21	AP_Math: cope with co-located waypoints in location_passed_point()	13 years ago
Andrew Tridgell	468dfe3faa	AP_Math: the windows arduino build is missing acosf()	13 years ago
Andrew Tridgell	0bdce404a5	AP_Math: add include of math.h this is needed for location.cpp	13 years ago
Andrew Tridgell	be9b9f3e67	DataFlash: fixed SITL build	13 years ago
Andrew Tridgell	dd24330645	DataFlash: fallback to BlockErase if ChipErase fails The errata on the APM2 dataflash chip says that ChipErase may not work on some chips	13 years ago
Andrew Tridgell	dd200cba31	Math: added location functions to math library these do common calculations on struct Location	13 years ago
Andrew Tridgell	1314e4f872	AHRS: make P gain on PI roll/pitch controller tunable this is to make it easier for Craig and Alan to tune	13 years ago
Andrew Tridgell	060cbe2030	AP_Mount: removed unused enum	13 years ago
Andrew Tridgell	99b11e4f19	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.	13 years ago
Andrew Tridgell	057eb5e6f6	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	13 years ago
Andrew Tridgell	f70cd71791	Baro: fixed build of MS5611 test code	13 years ago
Andrew Tridgell	769011e947	AnalogSource: added some example code	13 years ago
Andrew Tridgell	1fdcc3e8f0	SITL: added support for new analog source removed analogRead() to prevent people using it	13 years ago
Andrew Tridgell	c8befe4536	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	13 years ago
Andrew Tridgell	136c03c3c0	AHRS: include the P terms in get_gyro() this makes it more useful for navigation controllers	13 years ago
Andrew Tridgell	acc6adf6e9	MPU6k: removed an unused variable	13 years ago
Andrew Tridgell	ed691fc465	SITL: added SITL class for controlling simulation this holds mavlink settable parameters for controlling sensor noise levels	13 years ago
Andrew Tridgell	16c55c64d4	AHRS: don't add the P terms in _omega this can lead feedback via the _P_gain()	13 years ago
Andrew Tridgell	37fc6c46b9	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.	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	a6543f1e84	SITL: removed an unused variable	13 years ago
Andrew Tridgell	5bccfbd94c	Barometer: fixed airstart for APM we need to re-load the ground pressure and temperature from eeprom on and airstart	13 years ago
Andrew Tridgell	8e044a560b	AHRS: include P term in omega thanks to Jon for suggesting this	13 years ago
Andrew Tridgell	37e2f2ee2c	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	13 years ago
Andrew Tridgell	e4a245179c	AHRS: cope with copters with no compass if a copter doesn't have a compass, we can't use the GPS for gyro drift correction	13 years ago
Andrew Tridgell	f4faf941e2	GPS: test the more modern MTK16	13 years ago
Andrew Tridgell	27761737ce	SITL: fixed GPS heading in simulated UBlox longitude scale does not apply to velocity->heading conversions	13 years ago
Andrew Tridgell	b811653800	SITL: changes UBlox simulation to 5Hz this matches the real UBlox driver	13 years ago
