- Inline code that needs to take and release the lock in init()
function, just like other drivers
- Minor changes to coding style and renames to be similar to other
drivers
This compass has been proved to work better on Navio boards. Users also
don't like high offsets (even though, they don't really mean much in
this context) reported by AK8963 in MPU9250 on Navio 2.
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.

Summary of significant changes:
-Autsave doesn't depend on STREAM_EXTRA3
-Don't risk only saving one compass on copter if CAL_ALWAYS_REBOOT is set
-Only calibrate compasses that are both health and marked for use (there was a inconsistency in handling the mask)
-Fix incorrect failure reporting on DO_ACCEPT_MAG_CAL with a mask of 0 if a channel was specifically not started
-Fix not starting the buzzer if the delay is set to 0 seconds
-Always send MAG_CAL_REPORT until its acknowledged
-Correct the field in MAG_CAL_REPORT for autosave to indicate if the compass had actually been saved, rather then being scheduled to be saved
-Remmove unused public interfaces
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file. Having the makefiles
there is misleading since people try to build and realize the build is
broken.
The minimum version for gcc was supposed to be 4.9 for any platform.
However our build instructions are outdated. Remove the problematic
parts that use the sparse-endian.h header while we don't fix the setup
for windows.
- Correctly sort includes and add missing AP_Math.h
- Use anonymous struct for trim_registers in _load_trim_values,
renaming its members so they don't start with underscore
- Don't change _dig* values when we failed to read from sensor
- Add some blank lines
- Make _dig_* members be inside a _dig struct
- Use constrain_int32 instead of if/else chain
- s/time_us/time_usec/
- Construct raw_field with a single constructor in _update()
- Add missing copyright notice
- Group methods together in declaration
In addition:
- bbbmini, navio and navio2 can force HMC5843 backend to
be external.
- there was a typo in the backend name that's now fixed:
AK8953 vs AK8963
Minlure has an onboard compass (HMC5883L) as slave of MPU-6000, but also
allows the use of an external HMC5883L compass, which should be
connected to the lure's I2C port.
That rotation is done because of the "arrow" pointing the sensor direction in
3DR GPS+Compass kit (which isn't natural to the sensor orientation, by the
way). Thus, do that rotation only for external HMC5883L compasses.
That rotation is set for AP_COMPASS_TYPE_HMC5883L, because it's usually
the compass from 3DR GPS+Compass kit, which has an arrow pointing the
"correct" direction. That rotation should be done before rotate_field()
as it represents the "standard" position for the kit.
This patch also makes published values consistent with respect to rotation.
Before this, raw fields used in calibration were published with a
rotation different from the filtered field when _product_id is
AP_COMPASS_TYPE_HMC5883L.
And to the detection probe() method. That way we don't need to use a board
`#ifdef` inside the class code. Additionally, we make raspilot board use it.
Initialization was also changed a little bit so we don't try to
initialize 25 times. We rather use the same methods as in the
AP_InertialSensor drivers.
Also move up the call to is_zero() in read_raw so we don't set
_mag_[x|y|z] in case of failure.
These are not used. The only place where raw fields are used are in the
compass calibrator and we don't need to store them.
Additionally remove duplicated documentation about the meaning of the
functions to avoid them getting out of sync.
