Tom Pittenger 2620a57700 AP_InertialSensor: Added is_still() check
very strict check that all axis are not vibrating much at all
new param: INS_STILL_THRESH used to be a vibration threshold for different platforms
// @Description: Threshold to tolerate vibration to determine if vehicle is motionless. This depends on the frame type and if there is a constant vibration due to motors before launch or after landing. Total motionless is about 0.05. Suggested values: Planes/rover use 0.1, multirotors use 1, tradHeli uses 5

Gustavo Jose de Sousa 7789aec85b AP_InertialSensor: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Lucas De Marchi 4d4dac867e AP_InertialSensor: pass backend instead of pointer to function
Different detect() function might need different arguments and passing a
pointer to function here is cumbersome. For example, it forces to have a
method like "detect_i2c2" rather than allowing hal.i2c2 to be passed as
parameter.

Andrew Tridgell ac3200fd32 AP_InertialSensor: make max_abs_offsets a single float, not a vector 2015-06-30 10:51:43 +10:00
Gustavo Jose de Sousa 42eb73a1d1 AP_InertialSensor: add LSM9DS0 backend
This adds the backend driver for LSM9DS0. This implementation is based on the
legacy driver coded by Víctor Mayoral Vilches (under folder LSM9DS0) and makes
some necessary adaptations and fixes in order to work properly. The legacy
driver folder was removed.

Gustavo Jose de Sousa c340e072f2 AP_InertialSensor: use accel instance max abs offset instead of a constant value
The calibration on LSM9DS0 was giving offsets between 4.0 and 4.2 on x-axis and
around 3.6 on y-axis. It turned out that those offsets were actually right.

The maximum absolute values of calibration offset should be a sensor
characteristic rather than a constant value for all sensors.

The constant value previously used (3.5 m/s/s for all axes) is set here as a
default maximum absolute calibration offset for every instance to keep it
working.

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

Andrew Tridgell f3314791f2 AP_InertialSensor: removed INS_CALSENSFRAME

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

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 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
