Andrew Tridgell 0eac781559 AP_Compass: don't run the AK8963 on the external MPU9250
this saves us one mag slot for another external mag, and leaves the
primary MPU9250 undisturbed by the mag traffic on the bus

Andrew Tridgell d2f6a514b9 AP_InertialSensor: catch FIFO alignment errors using temperature reading
Two cases of what seems to be FIFO alignment errors have been seen on
a Pixracer-beta board with a ICM-20608. At a cost of 2 extra bytes per
transfer we can catch these by looking for sudden temperature changes
caused by bad data in the temperature registers.

Andrew Tridgell f31a017ace AP_Compass: changes to HMC5843 driver
this makes the HMC5843 use single-shot mode, which makes it more
robust to bus resets. It also adds WHOAMI checking and enables
automatic temperature compensation.

Unfortunately this makes existing calibration values incompatible, so
a re-cal is required. The device ID has been changed to reflect the
driver change.
2016-11-09 17:08:10 +11:00
Andrew Tridgell f62851f780 GCS_MAVLink: added remote device operations

Support for this is in the devop MAVProxy module

Andrew Tridgell 106a91c64c AP_InertialSensor: use init_gyro() on startup

2016-11-09 17:08:06 +11:00
Lucas De Marchi 104e29acf2 AP_InertialSensor: MPU6000: change accel scale to 16G
Also change the ID of MPU6000 so previous calibration values are not
considered valid.
2016-11-09 17:08:06 +11:00
Lucas De Marchi dc09661b9e AP_InertialSensor: MPU6000: save driver version
When registering accel and gyro we use the upper 16bits of the id to
store the driver version. When changing the driver behavior in
non-compatible ways, changing this version will trigger a request for
calibration.
2016-11-09 17:08:06 +11:00
Lucas De Marchi 0d3adef8b2 AP_InertialSensor: MPU6000: remove TODO leftover
This will never be done as blindly changing speed is not the way to fix
communication issues.
2016-11-09 17:08:05 +11:00
Andrew Tridgell 0a1616cc71 AP_InertialSensor: use correct device IDs on PX4 driver 2016-11-09 17:08:05 +11:00
Lucas De Marchi 469efb00f6 AP_InertialSensor: save id for gyro and accel instances
This allows each sensor to be uniquely identified in the system by using
either the index inside the backend or for those that use the Device
interface, to use the bus type, location, and device id.

We leave 16-bit for each sensor to be able to change its own
identification in future, which allows them to be changed in an
incompatible manner forcing a re-calibration.
2016-11-09 17:08:05 +11:00
Lucas De Marchi bbb9bfa95e AP_InertialSensor: save only gyro calibration
When we are initializing the gyro and then saving the calibration we are
also saving the calibration values for the accelerometers. Right now
this is non-problematic, but we want to check that the ID of the
accelerometer corresponds to the ID of the sensor detected. If we also
save accel calibrations we would actually override the ID of the
accelerometer.

Rename the method to _save_gyro_calibration() and save only on gyro
values.
2016-11-09 17:08:05 +11:00
Lucas De Marchi f81dba2100 AP_InertialSensor: add doc to get_id() of backend
This is different from get_id() of Device and ultimately from each
sensor this this is identifying the backend, not the sensor.
2016-11-09 17:08:05 +11:00
Lucas De Marchi 6b88f3367b AP_Common: remove AP_PRODUCT_ID_* macros
These are not used anymore.
2016-11-09 17:08:05 +11:00
Lucas De Marchi ace61087a1 AP_InertialSensor: remove product_id
We only leave the parameter there for backward-compatibility. However
product id on the inertial sensor is not much useful since it's only
kept for the first instance.

A better implementation per-gyro and per-accel is needed in order to
avoid problems with sensors taking the offsets configured for another
sensor.
