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!
 2012-03-12 17:33:15 +11:00
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).

Andrew Tridgell 60185509f4 AP_Compass: when I2c fails, don't retry for 1s 2012-01-04 16:35:47 +11:00
Andrew Tridgell acf4e9b61d I2C: convert compass code to new I2C library 
this also adds a healthy attribute, and error checking on all I2C
calls

tridge60@gmail.com 0bf026e6ad Compass: added a gain multiplier 
this adjusts the calibration based on the change in gain between
calibration and runtime

tridge60@gmail.com ab04055c35 Compass: several fixes to compass calibration code 
this changes the calibration code to require at least 5 good reads
from the compass during initialisation. The calibration is taken as
the average of the 5 values.

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.

tridge60@gmail.com a604e30c7c cope with double initialisation of the compass 
if we've already initialised, then the orientation matrix will already
be right

tridge60@gmail.com 7d58916a9d compass: add a small delay in compass init 
this adds a 50ms delay after setting the compass gains before reading
the compass. Added as paranoia after some strange results on a 5843

tridge60@gmail.com 165643c307 fixed 5843 detection code 
we were looking for the wrong regA value

Thanks to Chris for the debugging help! (and happy birthday!)

tridge60@gmail.com 7b803a9e1a compass: added error checking on I2C transactions 
this adds error checking to all operations on the compass, to ensure
that we don't accept invalid data

This also fixes the calibration values for the 5883L to match the
recommended values in the spec

tridge60@gmail.com 90b0d769f8 compass: fixed normal operation mode change for 5883L 
We need to set the right rates after config too. Thanks to Randy for
spotting this one

tridge60@gmail.com d46536e142 compass: fixed output rate and averaging for 5883L 
we need to setup the right output rate, or the compass gets very laggy

tridge60@gmail.com 2605c4b4b2 AP_Compass: fixed calibration of 5883L compass 
this fixes a compass initialisation bug where if the first value from
the compass isn't in the right range we would set bad calibration
scaling factors.

This also changes the maximum acceptable calibration values to 2000,
which is needed for the 5883 compass

Most of the compass functionality is now abstracted in a base class, with the various sub-classes implementing just their unique functionality.
