Andrew Tridgell fed5426274 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 89b4a9f4ed Quaternion: use gyro drift value from sensor driver 2012-03-10 10:34:34 +11:00
Andrew Tridgell fd74414884 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 1002bbcbfe SITL: cleanup the gyro drift calculations 
use units that are more easily understood
 2012-03-10 10:34:34 +11:00
Andrew Tridgell ad21913605 Quaternion: make the quaternion test more generic 
works with DCM too
 2012-03-10 10:34:33 +11:00
Andrew Tridgell a889135e78 Quaternion: update to get_gyro_drift() interface 2012-03-10 10:34:33 +11:00
Andrew Tridgell e0cc9c93a1 Quaternion: removed some unused variables 2012-03-10 10:34:33 +11:00
Andrew Tridgell f39d8dbde8 GCS: get_integrator() is now get_gyro_drift() in DCM 2012-03-10 10:34:33 +11:00
Andrew Tridgell b67b0afd10 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 f4b1dae7cf 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 f46fba54dc 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 9e07fa3af6 DCM: removed the limit on linear acceleration 
we get linear accelerations of more than 1g when turning corners
 2012-03-10 10:34:33 +11:00
Andrew Tridgell 4f739ea28f make 'ENABLE' and 'ENABLED' mean the same things 
users get this wrong far too often!

Andrew Tridgell f5e5ccff6a DCM: code cleanup and added more comments 2012-03-10 10:34:32 +11:00
Andrew Tridgell e2b2c9181e Quaternion: bumb up gyro drift limit to match DCM 2012-03-10 10:34:32 +11:00
Andrew Tridgell a874f920d5 ACM: removed the ADC filtering code 2012-03-10 10:34:32 +11:00
Andrew Tridgell 2b6fae6e16 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 404a4e4896 ADC: use floats for ADC averaging 
this costs almost nothing and improved accel/gyro calibration
 2012-03-10 10:34:32 +11:00

 2012-03-10 10:34:31 +11:00
Andrew Tridgell 4c6afa36cb 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
