c21d058110 Flight: Added ability to use a third accessory input. Currently using that to select tuning roll/pitch bias and PID tuning. I also _STRONGLY_ recommend if you enable these accessory channels (and thus these features) you make the saved meta data for the StabilizationSettings and AttitudeSettings read-only, so only on flights where you mean to can you change these settings. I'm also not convinced about the interface - it seems like flicking TX switches to get into adjustments is a recipe for disaster. Probably need to just control through GCS.

45e8131a30 Flight: Added ability to use additional TX inputs to tune attitude bias. Note this form of the calibration is temporary and will likely be replaced by a rotation matrix to deal with more general rotations.

b4ff14b725 Ground/GCSControl: Swapped sign conventions of sticks to match the sign convention of roll/pitch/yaw. I.e. now right on the roll causes a + roll, pulling down on the pitch causes + pitch.

a406034ed9 OP-132 Flight/AHRS: Changed the heuristics regarding GPS quality and INSGPS updates. Now if satellites < 7 or PDOP > 3.5 it does not perform GPS updates. Professor is working on some code to fix parts of the covariance matrix. If indoor updates high a 0 position and velocity and high variance.

65dc5e9b04 Yaw stabilisation for the simple algorithm was calculating the error and not taking into account that 350º error is the same as -10º error. 
The resultant error could range from -360º -> +360º
Since this is only used for Helicopters / multi rotors, and the aircraft can rotate in any direction, I added the modulo logic so that it is now from -180º -> +180º this should now take quickest path to correct the error.

3c6d9d6976 manual control was mapping tx input as -180º -> 180º for AttitudeDesired.Yaw. 
The Wiki (http://wiki.openpilot.org/Unit_Standards) states this should be 0 - 360º

f202884ce8 AHRS: Numerous changes. Added CPU load monitoring for AHRS as well as some friendly debugging output options. Also added a new CalibrationMode setting to AHRS (Echo) to speed up sensor calibration. Cleaned up the 6 point calibration interface to make it more friendly, but I think Edouard will clobber it with something nice and sexy :).

ecac1fb79d nmea: parse GSV sentences and populate GPSSatellites object 
This creates a new UAVObject called GPSSatellites to hold
information about which satellites the GPS receiver can see
and the quality of their signals.

NMEA GSV sentences are now parsed.  The full set of GSV data
may be split across multiple GSV sentences, each containing
info for at most 4 satellites.  Once an entire set of GSV
records has been collected, the GPSSatellites UAVObject is
updated.

16361dea12 AHRS: Making AHRS populate the NED/Vel fields of PositionActual. May rename object to PositionVelocityActual. Also created a GPSTime object which is populated from the GPRMC command. Also added a GPZDA parsing command, but by default OP GPS doesn't send this command. Made the computation of the world magnetic model use the current time to set the magnetic vector. Note: currently if you set your home location and save it to SD, this will not recompute the vector over time. I'm not sure how sensitive this is.

24a4c6b791 gps: Update GPSPosition instead of PositionActual 
GPS module now updates GPSPosition UAVObject
rather than the PositionActual object.  The
GPSPosition object is intended to be consumed
only by the AHRS.  The AHRS will use this (and
other inputs) to compute a filtered version of
the position in the PositionActual object.

This commit will cause temporary breakage of the
GPS functionality in the GCS until the PositionActual
object is properly updated by the AHRS.  Most of the
GCS should continue to use PositionActual.  The only
exception to this might be any tool for specifically
visualizing the raw GPS state.

GPS.c is now only responsible for receiving a
complete NMEA sentence from the COM interface.

NMEA parsing is now factored out into NMEA.[ch]
which is where GPSPosition is now updated based
on the complete NMEA sentences obtained from the
GPS.

Latitude and Longitude are now encoded in a
fixed-point notation in units of degrees x 10^-7
to prevent truncation of precision due to encoding
into a float.

2361af19fb First attempt at ccpm mixing for single rotor helicopter. 
This has throttle and pitch curves implemented and can be configured for many swashplate configurations.

This has flown a 450 clone (with training wheels) and the ccpm worked well.

Still need to neaten up some stuff and work out how to implement yaw stabilisation in manual mode.

4ca10e92c7 OP-121 OP-122 Flight: Improved USB HID communication. 
1. Added reenumeration function and call it on USB init (device will appear after reprogramming now)
  2. Moved buffer.c to general flight/Libraries location
  3. Removed the 62 byte transmission limitation by adding a transmission buffer
  4. Sped up USB communication by increasing endpoint polling frequency

Note, that the nonblocking and blocking USB send functions are not blocking entirely correcting.  The blocking calls the nonblocking, and the nonblocking blocks until the last chunk has started tranmission if it's a big transmission.  The buffering I added would generalize to non-blocking nicely, but would require using the EP1(IN) callback to handle most of the tranmission.  This creates a lot of issues if one function is pushing data onto the buffer and the interrupt is sending.

Also changed ManualControl so it checks the active control values to determine the warning, so if GCS is controlling the warning light goes out.

cfd20922cd AHRS: Added the filtered data to the attitude raw object.
