Author	SHA1	Message	Date
Amilcar Lucas	46d20c2d6b	Remove unused function, remove unnecessary angle wrapping.	13 years ago
Amilcar Lucas	bccb07cbd0	Allow mount control when no AHRS exists ... Allow mount control on non stabilized axes	13 years ago
Andrew Tridgell	a72f6acef6	AP_Math: added get_distance_cm() to return in centimeters	13 years ago
Andrew Tridgell	165604a55c	AHRS: fixed HIL build	13 years ago
Andrew Tridgell	0f9fb2c64b	AHRS: added AHRS_GPS_GAIN parameter ... this allows control of how much GPS velocity information is used in doing centripetal correction in DCM	13 years ago
Andrew Tridgell	e1725e9ea5	AP_Param: added some docs on the eeprom header format	13 years ago
Craig Elder	6d3fdfc03a	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.	13 years ago
Amilcar Lucas	af338939be	RC_Channel: Improve documentation	13 years ago
Amilcar Lucas	46552b4222	AP_Mount: Fix radians/degrees scaling regressions ... Rename calculate() into stabilize() Implement MAV_MOUNT_MODE_RC_TARGETING initialization Document to make sure this radians/degrees mess up does not happen again	13 years ago
Andrew Tridgell	d755fedc26	AnalogSource: prevent a division by zero on zero ADC data	13 years ago
Andrew Tridgell	f6d7d1bc59	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	13 years ago
Andrew Tridgell	f501503eb0	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.	13 years ago
Andrew Tridgell	520d762382	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.	13 years ago
Andrew Tridgell	3c7e521f70	AP_Baro: update MS5611 test to use baro library altitude	13 years ago
Andrew Tridgell	302696951a	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	13 years ago
Andrew Tridgell	8c5ef3e60f	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	13 years ago
Andrew Tridgell	ec0995eea1	SITL: lower baro noise a bit	13 years ago
Andrew Tridgell	6534dab719	Filter: fixed DerivativeFilter example build	13 years ago
Andrew Tridgell	d29b6ce0a8	SITL: run the HIL barometer at 80Hz to match APM2	13 years ago
Andrew Tridgell	209136386b	AP_Baro: added get_pressure_samples() interface ... this returns how many samples were used to calculate the last pressure	13 years ago
Andrew Tridgell	1a42b10255	Filter: fixed typo in 9 point DerivativeFilter	13 years ago
Andrew Tridgell	185c6e5b32	AP_Baro: change to a 7 point DerivativeFilter for climb rate	13 years ago
Andrew Tridgell	75470dc912	Filter: cope with non-uniform time steps in the DerivativeFilter ... this helps with the barometer a lot, as the timing is quite variable	13 years ago
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
Andrew Tridgell	9f8703274c	AP_Baro: show climb rate in baro test sketch	13 years ago
rmackay9	b5f47f5e63	AP_Motors: clarified some doxygen descriptions for TradHeli	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
