Andrew Tridgell 007b01533d AP_InertialSensor: switched to 16g accel range for MPU9250 
this matches the Pixhawk, and makes us less prone to vibration. We
have seen clipping at 8g

Lucas De Marchi b292873304 AP_InertialSensor: fix starvation in L3G4200D 
The main thread would always be blocked on the semaphore to read the
data from accelerometer and gyroscope. Especially if we have a slow
update of these values in _accumulate() due to the I2C transfer function
taking too much time: the timer thread would never give up the CPU,
causing starvation on the main thread.

This fixes the issue by reducing the critical region using a flip-buffer
so _accumulate() can work on its own copy of the data. Now that the
critical region is smaller, also avoid the semaphore and use a spinlock
instead.

Andrew Tridgell 4147825b87 AP_InertialSensor: fixed gyro calibration bug 
we must not update _gyro_offset[] until we have completed calibration
of that gyro, or we will end up using the new offsets when asking for
the raw gyro vector
 2015-04-03 06:57:30 -07:00
Andrew Tridgell 23272e4013 AP_InertialSensor: added get_temperature() interface 
this will allow logging of individual temperature sensors

Andrew Tridgell 07fd31c724 AP_InertialSensor: change copter filters to 20Hz 
with the backend filters disabled 20Hz is closer to the old default of
30Hz
 2015-03-12 13:11:17 +11:00
Andrew Tridgell a1d43e39e0 AP_InertialSensor: added get_gyro_filter_hz() and get_accel_filter_hz() 2015-03-12 12:50:31 +11:00
Andrew Tridgell 3d7d46b9b0 AP_InertialSensor: replaced INS_MPU6K_FILTER with INS_ACCEL_FILTER and INS_GYRO_FILTER 
this allows filtering to be set separately on accels and gyros where possible
 2015-03-12 12:50:31 +11:00
Andrew Tridgell f3314791f2 AP_InertialSensor: removed INS_CALSENSFRAME 
it is no longer needed as we have shifted the accel cal indexes
 2015-03-12 12:50:31 +11:00
Andrew Tridgell 4bc6c8e655 AP_InertialSensor: shift to new parameter indexes for accel calibration 
this allows for users to switch between development trees and previous
stable versions while retaining their accel calibration values.

Andrew Tridgell 5d0eb49114 AP_InertialSensor: calculate queue depth based on requested sample rate 
this auto-scales the queue depth for plane, rover and copter
 2015-03-12 12:50:30 +11:00
Andrew Tridgell ea49d1cd39 AP_InertialSensor: removed unused variable 2015-03-12 12:50:30 +11:00

Andrew Tridgell 875339f12a AP_InertialSensor: try to avoid a compiler fault in travis 2015-03-12 12:50:29 +11:00
Andrew Tridgell 786172aa4e AP_InertialSensor: removed 1D accel calibration 
it is finally time to move on from this. We want to push people
towards better calibration and removing the 1D accel cal is the first
step
 2015-03-12 12:50:28 +11:00
Andrew Tridgell a975520033 AP_InertialSensor: check range of accels in 3D calibration 
during 3D accel cal it is possible to get data which passes the sphere
fit but which has very poor coverage and does not provide sufficient
data for a good result. This checks that each axis covers a range of
at least 12 m/s/s in body frame
 2015-03-12 12:50:28 +11:00
Andrew Tridgell a8a8628515 AP_InertialSensor: added INS_CALSENSFRAME parameter 
this allows us to detect if accel calibration was done in sensor frame
or not. If it was done in sensor frame then the accel calibration is
independent of AHRS_ORIENTATION, which makes it easier to move a board
to a new airframe without having to recalibrate.

Andrew Tridgell 494e909703 AP_InertialSensor: ensure accel cal completion messages get through 2015-03-09 07:36:50 +11:00
Andrew Tridgell 38bde56523 AP_InertialSensor: continue finding best gyro after convergence 
with multiple gyros if we are still calibrating one of the gyros then
keep looking for better values for the already converged gyros.
 2015-03-08 07:49:38 +11:00
Andrew Tridgell 20a4c98bac AP_InertialSensor: use accelerometers to prevent bad gyro cal 
if the board is rotating at a steady rate we can end up with a bad
gyro calibration. This can happen on a steadily moving platform such
as a ship.

This uses the accelerometers to detect the steady movement and not
accept the gyro calibration
 2015-03-08 07:48:16 +11:00
Andrew Tridgell 434d094993 AP_InertialSensor: allow MAVLink packets to flow during accelcal 
this uses the snoop functionality of GCS_MAVLink to allow the delay
callback to be used during accel calibration
 2015-03-07 21:56:39 +11:00
Randy Mackay b650d39786 InertialSensor: remove product_id set to zero 2015-02-21 09:14:33 +09:00
Andrew Tridgell 9b2d44d6ed AP_InertialSensor: use delay_microseconds_boost() 
this gives much more consistent timing for PX4
 2015-02-16 12:19:13 +11:00
Andrew Tridgell f54d799bff AP_InertialSensor: added TIMING_DEBUG code for finding loop timing issues 2015-02-16 10:12:10 +11:00
Andrew Tridgell 04bef5ccf3 AP_InertialSensor: don't skip delay if we are a bit early 
this produces a bit more even timing
