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

Andrew Tridgell 7b51c907f5 AP_Compass: zero some more variables in constructor and init 2015-03-13 19:22:11 +11:00
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.

Víctor Mayoral Vilches d3b76cd8d3 AP_Compass: split compass into frontend/backend 2015-03-13 18:46:15 +11:00
Staroselskii Georgii 7f00dd413f AP_Compass: fixed HMC5883's initialisation code 2014-11-14 10:21:04 +11:00
Jonathan Challinger 9054dd3f9a AP_Compass: use apply_correction_function to eliminate duplication 2014-10-19 17:02:45 +11:00
Randy Mackay 86aac4f40c Compass_HMC5843: use instance specific orient and external 2014-10-01 13:02:03 +10:00
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

Andrew Tridgell cb16733918 AP_Compass: switched to a vector based interface
this is more consistent with other APIs and makes multi-device support
easier

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.

Andrew Tridgell 1ccd6bb7ef AP_Compass: don't wait more than 1ms for compass sample

Andrew Tridgell 97b7130bb9 libraries: update license header to GPLv3
we switched to GPLv3 a long time ago, but neglected to update the
per-file license headers
2013-08-30 13:01:39 +10:00
Andrew Tridgell 217f34e155 AP_Compass: added COMPASS_ORIENT parameter, to support external compasses
this allows the user to configure the compass for any orientation
supported by our rotation library

Randy Mackay d8515ff85e Compass: basic compensation for motor interference 2013-03-02 00:03:16 +09:00
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.
- Include AP_Math.h rather than math.h to get these definitions.
2013-01-16 13:52:17 +11:00
James Bielman 5631f865b2 Update floating point calculations to use floats instead of doubles.
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

  HMC5843 drivers.

Andrew Tridgell 7daaadf776 Compass: fixed the order of rotations in the compass driver
this should fix the massive heading issues that people have been
reporting. Please test!

Andrew Tridgell 0da64e98f8 Compass: don't save the orientation to EEPROM
there is no point in saving this, the value is only configurable at
compile time for now, and is always set
2012-03-11 15:37:07 +11:00
Andrew Tridgell cb96dd975f Compass: update the compass driver to use the new vector.rotate() method 2012-03-11 15:37:07 +11:00
Andrew Tridgell 6eff9107ea Compass: change last_update to be in microseconds 2012-03-10 10:34:32 +11:00
Andrew Tridgell d0a6359b37 Compass: use constructor to set initial values for _learn and _use_for_yaw
this ensures they are set if you have MAG_ENABLE==0
2012-02-25 17:36:31 +11:00
Andrew Tridgell f59297d7a7 Compass: catch the case of a user enabling a compass mid-flight
if a compass has not been initialised at startup we can't enable it
mid-flight, as we don't have the orientation
2012-02-25 14:51:09 +11:00
Andrew Tridgell 664622523d Compass: added COMPASS_LEARN and COMPASS_USE parameters
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1

Andrew Tridgell 8c58d95187 modify the compass code for AP_Param 2012-02-13 16:22:51 +11:00
Randy Mackay ed19c25a97 Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h".
Modified FastSerial's write function to return size_t (number of bytes written).
