Andrew Tridgell ba8e764349 SITL: lower the noise and drift levels for general autotest usage 2012-03-10 10:34:34 +11:00
Andrew Tridgell b02ca58901 InertialSensor: fixed HIL build 2012-03-10 10:34:34 +11:00
Andrew Tridgell 44ebb20329 MAVLink: bring the v1.0 MAVLink in sync with 0.9 2012-03-10 10:34:34 +11:00
Andrew Tridgell 87c463bcc7 DCM: after some experimentation, raise the ki values a bit
this tracks the max gyro drift more accurately
2012-03-10 10:34:34 +11:00
Andrew Tridgell eff6778515 Quaternion: use gyro drift value from sensor driver 2012-03-10 10:34:34 +11:00
Andrew Tridgell 3989fe2c2c Quaternion: go back to the full update_MARG()
the separate drift controller is too erratic on yaw hold to be usable
at the moment
2012-03-10 10:34:34 +11:00
Andrew Tridgell c8189c80d4 SITL: cleanup the gyro drift calculations
use units that are more easily understood
2012-03-10 10:34:34 +11:00
Andrew Tridgell b833190abb Quaternion: make the quaternion test more generic
works with DCM too
2012-03-10 10:34:33 +11:00
Andrew Tridgell 2f9af05cfa Quaternion: update to get_gyro_drift() interface 2012-03-10 10:34:33 +11:00
Andrew Tridgell bf16b2926c Quaternion: removed some unused variables 2012-03-10 10:34:33 +11:00
Andrew Tridgell 3b2609c441 DCM: separate out the omega_yaw_P from omega_P
this cleans up the separation of drift rates and proportional
correction from yaw source and accelerometers, allow the yaw
to run at a different rate to the accel correction
2012-03-10 10:34:33 +11:00
Andrew Tridgell bcb7196680 IMU: added get_gyro_drift_rate() interface
this just calls down to the InertialSensor layer
2012-03-10 10:34:33 +11:00
Andrew Tridgell 9296ac494d AP_InertialSensor: added a get_gyro_drift_rate() interface
this returns the expected max drift rate for the particular type of
gyro being used
2012-03-10 10:34:33 +11:00
Andrew Tridgell 882fa1818b DCM: removed the limit on linear acceleration
we get linear accelerations of more than 1g when turning corners

Andrew Tridgell 9dc08b30cd Quaternion: bumb up gyro drift limit to match DCM 2012-03-10 10:34:32 +11:00
Andrew Tridgell f9394f8068 ADC: removed the ADC level accel smoothing
the quaternion code does a better job of handling this noise than this
filter does
2012-03-10 10:34:32 +11:00
Andrew Tridgell 8b40c44522 Quaternion: separate out drift correction from main updates 2012-03-10 10:34:32 +11:00

Andrew Tridgell 4dff78b9c0 GPS: expose last_fix_time 2012-03-10 10:34:32 +11:00
Andrew Tridgell 6eff9107ea Compass: change last_update to be in microseconds 2012-03-10 10:34:32 +11:00
Andrew Tridgell a0a360f955 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 045b49c4c4 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
2012-03-10 10:34:31 +11:00
Andrew Tridgell 321200ebbc AP_IMU: fixed led flashing in gyro cal

2012-03-10 10:34:31 +11:00
Andrew Tridgell 8abbbe5713 AP_Math: better way of handling safe_sqrt()
better to test the result, than predict it
2012-03-10 10:34:31 +11:00

Andrew Tridgell 066a513758 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 c7d5f06b21 AP_Math: added quaternion helper functions and a test suite 2012-03-10 10:34:30 +11:00
Andrew Tridgell f70dfe440d 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 47ddd4dfdd SITL: disable interrupts during register updates
this may prevent bogus mode channel reads
2012-03-10 10:34:30 +11:00
Andrew Tridgell 7256652de5 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 c7ef72cf28 Quaternion: don't update if we have a very long deltat
this can be caused by stopping the system in a debugger
2012-03-10 10:34:30 +11:00
Andrew Tridgell 6d356b6c6e Compass: fixed last_update time for HIL compass 2012-03-10 10:34:30 +11:00

change
2012-03-10 10:34:30 +11:00
Andrew Tridgell 57f67ca6e3 GPS: added an acceleration estimate to the GPS driver
