Lucas De Marchi a66a201bf5 AP_Compass: HMC5843: Add support for MPU6000 auxiliary bus
Allow HMC5843 to be on MPU6000's auxiliary bus.

Lucas De Marchi 628e446e3e AP_Compass: HMC5843: use a struct for raw value
Like is done in AK8963, declare a raw_value struct.

Lucas De Marchi 9ecd1daf81 AP_Compass: HMC5843: remove useless delay
There's no need to add a delay after suspending timer in the
initialization. Also initialize _bus_sem earlier, like is done in
AK8963.

Lucas De Marchi c66c9c41f2 AP_Compass: HMC5843: be agnostic to I2C bus
Like was done to inertial AK8963 and inertial sensor move the decision
regarding the I2C bus to the caller. We don't allow changing the address
because apparently HMC5843 doesn't support different addresses.

Changing only the bus could be more easily done but this prepares the
ground for using HMC5843 on an AuxiliarBus.

The need for a more generic abstraction is evidenced by this commit: a
"SerialBus" in AP_HAL would be a nice addition rather than letting each
driver to provide its own. However the methods are a little bit
different from what we have in AK8963. It's safer to do the simple
conversion now and later on to add the abstraction changing everybody to
use it.

Staroselskii Georgii 3eb6be64c9 AP_Compass: ignore first two readings in a clearer way
This way we don't mix two different conditionals: settling and data validation.

Staroselskii Georgii 633330db14 AP_Compass: rename calibration array in HMC
I think naming the variable "scaling" makes more sense.

Staroselskii Georgii d8bddcbf3a AP_Compass: fix indentation in HMC's driver 2015-08-28 12:39:09 +10:00
Staroselskii Georgii 79ffddc6db AP_Compass: add a macro for checking calibration values in HMC 2015-08-28 12:39:08 +10:00
Lucas De Marchi f61386ae43 AP_Compass: HMC5843: release the lock before read
read() calls accumulate() which takes the lock by itself so we must
release it like we were doing before 669ae26 ("AP_Compass: encapsulated
calibration in HMC").

Gustavo Jose de Sousa 58f300e78e AP_Compass: 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.

Andrew Tridgell 1962706a33 AP_Compass: fixed last_update, using last_update_usec()
this broke use of compass in the EKF

Andrew Tridgell 0efd3bacea AP_Compass: make new backend match old PX4 behaviour
when a compass is internal only apply board orientation, not user
specified rotation

Víctor Mayoral Vilches 13f0aa5ecd AP_Compass: Separate common code into backend
_copy_to_frontend function takes care of abstracting
this code from the driver. For now the function takes
care of the offset and rotation that is common.

Andrew Tridgell 54562b0b9a AP_Compass: prevent bad initial values from affecting HMC5883 calibration
the first couple of values after we enter strap mode may be low, but
just above our 0.7 threshold. We now discard the first two values to
prevent these affecting the average.

Also added some commented out debug code and a comment on the scaling
of the calibration code

James Bielman 4fa7bb1486 Add AVR compatibility header for missing math.h definitions.
- Define float versions of math functions to the double versions
  on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.
