Andrew Tridgell bc0ae630a1 AP_InertialSensor: always provide delta_velocity and delta_angles
this makes the NavEKF code simpler
2015-06-17 13:10:26 +10:00
Andrew Tridgell f831c16238 AP_InertialSensor: use fixed sensor sample times
this uses fixed sample times for PX4 IMUs, rather than reported
timestamps. It avoids timing jitter caused by the over-sampling in
the PX4 drivers

Lucas De Marchi 3aa46e3213 AP_InertialSensor: use functor macros
Functor is not yet being used but let's make is macro fallback to the
previous Delegate implementation for easy of transition between the two.

Randy Mackay 1f14eec4ea InertialSensor: accel_calibrated_all_ok replaces calibrated
This checks that the current number of accelerometers matches the number
of calibrated accels in order to catch accel failures at boot

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
2015-04-28 15:30:29 +10:00
Tom Pittenger a4b8575432 InertialSensor: fix compile warnings re float constants 2015-04-24 14:03:49 +09:00

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

Andrew Tridgell 07fd31c724 AP_InertialSensor: change copter filters to 20Hz

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

2015-03-12 12:50:31 +11:00
Andrew Tridgell 4bc6c8e655 AP_InertialSensor: shift to new parameter indexes for accel calibration

stable versions while retaining their accel calibration values.

Andrew Tridgell 5d0eb49114 AP_InertialSensor: calculate queue depth based on requested sample rate

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 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

Andrew Tridgell 745b739ab7 AP_InertialSensor: make calibrated() function fast enough to call in flight
this will be used in plane to make AHRS SYS_STATUS unhealthy if a user
tries to fly with EKF enabled without a full 3D accel cal.

Note that it doesn't rely on using AP_Param load() to detect that a
value has been set, as some users are first doing a 3D cal then later
doing a 1D cal. In that case load() was returning true and would give
a false positive
2015-01-03 14:06:42 +11:00
Andrew Tridgell 06a72839ed AP_InertialSensor: fixed error detection on secondary IMUs
