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

Andrew Tridgell f54d799bff AP_InertialSensor: added TIMING_DEBUG code for finding loop timing issues 2015-02-16 10:12:10 +11:00

Andrew Tridgell 1b3c3c754d AP_InertialSensor: use correct ifdef for AK8963 2015-01-07 11:58:05 +11:00
Staroselskii Georgii f7f9cd2173 AP_InertialSensor: prevented MPU9250 from disabling I2C slaves 2015-01-07 08:41:13 +11:00
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

Andrew Tridgell f84f432ecf AP_InertialSensor: allow gyro calibration to take up to 30 seconds 
this gives time for the user time to get their battery hatches on and
hold the model steady. 5 seconds was just far too short
 2014-11-22 18:27:51 +11:00
Andrew Tridgell 7c288e020b AP_InertialSensor: fixed detection of dead IMU 
if a PX4 sensor does not give new data we need to avoid calling
_rotate_and_offset_*() to avoid marking it as healthy. Otherwise if
the MPU6k dies we won't switch to the LSM303D automatically
 2014-11-16 12:30:33 +11:00
Andrew Tridgell 986b7bf894 AP_InertialSensor: fixed frequency to 16 bit in LDM303D and L3GD20 drivers 2014-11-11 17:06:22 +11:00

Andrew Tridgell 9dfbdb1e69 AP_InertialSensor: run the MPU6000 at 1kHz on fast CPUs 
use a software filter and 1kHz sampling for better filtering if we
have a fast enough CPU to do it
 2014-10-24 12:10:40 +11:00
Andrew Tridgell a047d1f569 AP_InertialSensor: moved default filter and sample_rate to frontend

Andrew Tridgell 448efc70a3 AP_InertialSensor: first steps in frontend/backend split

Andrew Tridgell 3c2ab31415 AP_InertialSensor: get rid of data_ready for MPU9250 
when running off a 1kHz timer and reading at 1kHz it is better to
double sample than it is to skip a sample, as skipping samples will
throw the filter off, whereas a double sample will have minimal effect
 2014-08-19 20:03:33 +10:00

 2014-08-19 10:08:15 +10:00
Víctor Mayoral Vilches bfacf08c30 HAL_Linux: LSM9DS0 legacy driver moved to AP_InertialSensor/LSM9DS0/ 
The new LSM9DS0 driver will consist of the AP_InertialSensor_L3GD20 and
the AP_InertialSensor_LSM303D. For that reason the old LSM9DS0
(consisting of gyro and accel+mag implemented on a single class) has
been moved to a folder.

Legacy LSM9DS0 didn't probe to receive "correct" data.

Andrew Tridgell 770b7b5901 AP_InertialSensor: prevent a lockup in MPU6000 driver 
thanks to the VRBrain port for noticing this bug.

Failing to get the semaphore is an expected error with the MPU6000, as
we read data both from timer context and mainline code. That means
semaphore conflicts are inevitable. We shouldn't consider them an
error, and shouldn't panic when some arbitrary number of them have
happened since boot.

Instead the wait_for_sample() code checks that we receive new data at
least every 50ms. That is a much safer test.

Andrew Tridgell 5643c371b9 AP_InertialSensor: removed unused new_data_available() and temperature() APIs 2013-02-07 10:23:37 +11:00
Andrew Tridgell 7b1245937c AP_InertialSensor: always sample at 200Hz in MPU6000 
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.

This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration
source

using the MPU6k sample timing instead of micros()
