Andrew Tridgell cab3630009 AP_InertialSensor: switched to supplying timestamps for SITL 
this allows the time step to change on each loop as we no longer use
the average sensor rate when calculating deltas

Andrew Tridgell 58708c483f AP_InertialSensor: make all semaphores recursive 
the cost is very similar and this prevents an easy coding error which
can occur on less used code paths
 2020-01-19 20:19:30 +11:00
Andrew Tridgell b89c241329 AP_InertialSensor: use take_blocking instead of HAL_SEMAPHORE_BLOCK_FOREVER

needed
 2020-01-19 20:19:30 +11:00
Andy Piper 52f59fb573 AP_InertialSensor: more accurately compute INS noise taking throttle into account and adding frequency noise noisily

and removed dangerous default values for rotations
 2019-08-28 06:54:11 +10:00
Andrew Tridgell c99923d500 AP_InertialSensor: require gyro orientations in LSM9DS probe 
this prevents a bug where they are missing in hwdef.dat
 2019-08-27 19:29:37 +10:00
Andrew Tridgell 992016069a AP_InertialSensor: fixed watchdog on AHRS trim gyro wait 2019-08-19 14:37:46 +10:00

Randy Mackay 6a154c4e4c AP_InertialSensor: resolve gcs::send_text compiler warning 2019-07-30 09:02:39 +09:00
Andrew Tridgell 8e5c0fa32b AP_InertialSensor: disable kill IMUs with HAL_MINIMIZE_FEATURES 2019-07-07 19:03:01 +10:00
Andrew Tridgell 09d3392aee AP_InertialSensor: zero accumulators on time step 
this zeros the delta angle and delta velocity accumulators when a
sensor is unavailable for a period of 0.1s. This prevents garbage
values being passed into the EKF when a sensor dies and then becomes
available again some time later
 2019-07-07 19:03:01 +10:00
Andrew Tridgell 3444e82ef9 AP_InertialSensor: added RC switch for killing IMUs 2019-07-07 19:03:01 +10:00
Andrew Tridgell 053f0cb689 AP_InertialSensor: try much harder to get all IMU samples 
this we ensures we get new data for all active IMUs on each loop,
rather than sometimes returning with some IMUs not having data.

This matters as not having a sample on an IMU for a single loop can
cause an EKF IMU failover, which will degrade the learned bias
variances

The issue is usually only seen under high load, such as requesting a
loop rate beyond what the hardware is capable of
