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

Andrew Tridgell a871c87cad AP_Compass: use state array for compass variables 2015-03-13 18:46:15 +11:00
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.

 2014-05-25 22:03:44 +10:00
Jonathan Challinger e883b889b6 SITL: Add compassmot interference 2014-05-15 21:14:20 +10:00

Andrew Tridgell 485ae596fc AP_Compass: fixed last_update for secondary compass with primary failed 
this ensures EKF and DCM will use a secondary compass if the primary
fails
 2014-03-23 22:05:17 +11:00
Matthew Lloyd 60a4f74de6 AP_Compass: avoid division by zero if we haven't received any mag reports 
Otherwise, get_field() will return NaNs after once every few calls to
read() during compassmot on PX4 platforms, which causes compassmot to fail.

This is a quick hack around the deeper issue, which could be something
like the PX4 mag driver experiencing starvation and skipping mag reports,
buffer overrun or something else that causes mag reports to be dropped.
Or perhaps we should never expect in the first place that we will always
receive at least one mag report between calls to read().
 2014-03-23 21:22:32 +11:00
Andrew Tridgell db48ed9218 AP_Compass: fixed showing of is_external for 2nd compass 2014-03-13 16:26:43 +11:00

Andrew Tridgell 189d635493 AP_Compass: constrain compass offsets to +/- 2000 
this is prompted by a user log showing NaN compass offsets, resulting
in a crash. The patch ensures we never end up with NaN offsets, and
also constrains the offsets to a reasonable limit
 2014-02-16 13:33:41 +11:00
Andrew Tridgell 9bb8f73d56 Compass: split compass learning out to its own C++ file 2014-02-16 13:21:06 +11:00
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
 2014-01-22 17:15:34 +11:00

easier
 2013-12-09 17:34:06 +11:00
Randy Mackay 84fdff4cd6 Compass: slightly relax HMC5843 calibration limits 
Some users have reported Z axis values as high as 1.33.  Their compasses
seem otherwise health so extending the limits slightly.
 2013-11-27 15:36:34 +09:00
Andrew Tridgell 1ccd6bb7ef AP_Compass: don't wait more than 1ms for compass sample

 2013-09-09 18:04:40 +10:00
Andrew Tridgell b8b72819c1 AP_Compass: ignore COMPASS_ORIENT for internal compass 
this means if COMPASS_ORIENT is not 0 and the external compass fails
to start on boot we don't end up with a bad compass orientation
 2013-09-07 16:49:51 +10:00
Andrew Tridgell 9320e82ac2 AP_Compass: added in new orientations 2013-08-30 14:19:03 +10:00

Andrew Tridgell ba83950fc4 libraries: replace constrain() with constrain_float() 
this makes the type much more obvious. Thanks to Tobias for the
suggestion.
 2013-05-02 10:25:40 +10:00
Andrew Tridgell 0fce0eb488 AP_Compass_PX4: fixed handling of a saturated compass 
a saturated compass is now marked unhealthy, rather than causing the
code to spin waiting for a valid sample. This fixes a problem with
strong magnets causing the main flight loop to stop
 2013-05-01 08:54:53 +10:00

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.

Andrew Tridgell e4d28b12e5 Compass: remove the need to call calculate() on the compass object 
the new AHRS code doesn't use calculate() and the compass.heading
attribute. Instead it works on the raw magnetometer vector. This
change removes the internal calculate state from the compass object
and instead adds calculate_heading() for use by older code that
doesn't go via AHRS.

This significantly reduces the calculation involved in compass updates

The null offsets enable/disable code is also removed, as it is not
needed now that compass offsets are not linked to the AHRS state.

Doug Weibel e22a83eec0 Add a CLI setup action to reset the magnetometer offsets 
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

Doug Weibel 9846822748 Bug fix for compass. 
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.

this changes the calibration code to require at least 5 good reads
from the compass during initialisation. The calibration is taken as

This also fixes the expected values for the 3 axes for the 5883 to
match reality.

We also save a bit of code space by adding a common rotate_for_5883L()
routine.

DrZiplok@gmail.com cc06f07067 Major update including AP_Var support. 
Most of the compass functionality is now abstracted in a base class, with the various sub-classes implementing just their unique functionality.

DrZiplok 5faadf4cd1 use memset rather than explicit assignments to zero to zero an array, this saves code space.

DrZiplok eb81becdb6 Pure virtual classes should declare pure virtual member functions as 0, rather than having the linker go looking for implementations elesewhere. This lets the compiler generate better error messages when a subclass fails to implement one or more required functions.
