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.

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.

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

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

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).

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.

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 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

spotting this one

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
