this saves a few k of flash space

rmackay9 9b3ced93ee AP_Compass: fix for mismatching set_initial_location parameters (forgot to change long to int32_t in .cpp file) 2012-08-18 20:41:38 +09:00
Andrew Tridgell 518d6365ff AP_Param: update remaining libraries for new constructor syntax 2012-08-08 12:11:57 +10:00
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.

rmackay9 ef43da9b92 AP_Compass - changed parameter initialisation order to remove compiler warning 2012-04-09 17:37:02 +09:00
Andrew Tridgell 504c53f746 Compass: added COMPASS_AUTODEC option 
when this is 1 (which is the default), we will get the declination
automatically via the AP_Declination library

when it is 0 we will use the value configured by the user
 2012-03-30 14:25:27 +11:00
Andrew Tridgell 17290836ef Compass: added some more comments 
explain the algorithm a bit more
 2012-03-29 12:39:53 +11:00
Andrew Tridgell b2d6db9479 Compass: implement noise resistant varient of offset learning 
This adds a large amount of noise robustness to the compass offset
learning algorithm, at a cost of 120 bytes of memory. The changes are
based on a long discussion with Bill Premerlani.
 2012-03-28 20:55:27 +11:00
Andrew Tridgell a72d4b46b3 Compass: implement Bills new offset nulling algorithm 
this seems to work much better than the old algorithm, converging
faster and more accurately. Even better, it has no linkage to DCM, so
no possibility of nasty feedback effects
 2012-03-27 15:37:24 +11:00
Adam M Rivera fe8c896d69 AP_Declination: Added method set_initial_location 
This will set the declination based on lat/lon if the user has
not yet saved one to the EEPROM, OR if they have specified via the
config parameter that they want it to overwrite the declination every
3D fix.

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
rmackay9 fa34ac076e AP_Compass - fixed compile warning 2012-02-29 22:57:35 +09:00
rmackay9 c819a0f68a AP_Compass - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:45:49 +09:00
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 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
 2012-02-25 14:51:08 +11:00
Andrew Tridgell c354879f1f Compass: ensure we don't produce NAN values for compass heading 
this leaves the previous heading values alone if we are at a pitch of
exactly 90 or -90, at which point we can't compute a meaningful
heading
