098b2fd693 Flight/System: Double heart rate when system is armed. This is per request in
IRC, but suggestions are welcome.  In the long run we probably need a sensible
way of embedding some information in the LED but it's not obvious to me.  Also
could have done with callback - sue me. ;)

Flight: Create PositionDesired (the active waypoint) UAVObject and make the FlightSituationActual no update since it not used.
Flight: New velocity desired object that passes information between the look computing the desired velocity and the PID loop to get it (updated at different rates)
UAVObjects/PositionActual: Remove unused GPS fields
UAVObjects/PositionActual VelocityActual: Split the velocity into a separate object.  ALso make sure all the information telemetered around is in cm to avoid using floats.
UAVObject/GuidanceSettings: New guidance settings object for the guidance module
Flight/Posix: Add the new objects to the Posix sim
Flight/Guidance: Computes a desired velocity based on position error than runs a PID loop to control roll and pitch to achieve that velocity.  All distances are in cm, and updated the PositionActual fields to reflect this and use int32.

Calibration should take less time now too (using second moments to estimate
variance in one pass).  Now need to change to multiple messages to get the
calibration in to keep the request message size minimal.  Also currently
running sensor calibrate doesn't store the gyro bias so if you want to use this
you'll have to tweak it manually.  I'll fix that step tomorrow.

Les suggested this be in manual mode which will require changing the logic somewhat (essentially for vtol it will always be running through the Stabilization module) in an aircraft dependent manner. An alternative would be a stabilization flag indicating to do full attitude hold, attitude + yaw stabilization, or all axis gyro stabilization. This would be my preference.

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.

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.

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.

f74c6ffdd5 i2c: rewrite i2c layer
The STM32 I2C block has a number of errata associated with it.
These errata are primarily related to timing sensitivities between
the peripheral and the interrupt handler.  In particular, the
correct generation of the stop bit relies on the I2C IRQ running
immediately and not being held off for any reason.

NOTE: The I2C interrupts must be the highest priority IRQs in the
      system to ensure correct operation.

I2C protocol is now implemented as a formal state machine.
See: stm32_i2c_fsm.{dot,jpg} for FSM description.

I2C init is now expressed by const initializers in pios_board.c
for both OP and AHRS boards.

I2C device drivers (ie. bmp085/hmc5843) now pass in const arrays
of an unlimited number of bus transfers to be done atomically.
The I2C adapter driver now handles all bus-level locking across the
list of transactions.  Generation of start/restart/stop conditions
are handled automatically over the list of transactions.

Timeouts have been removed from the API for now.  May be added
back later.

This driver has run error free on both the OP and AHRS boards for
up to 48hrs but it still sometimes fails earlier than that on the OP
board.  There is another possible set of improvements to the driver
that could employ the DMA engine for transfers of >= 2bytes.  This
change would reduce the timing sensitivities between the peripheral
and the driver but unfortunately, both the SPI and I2C interfaces
share the DMA1 engine.  That means only one of these two peripherals
can use the DMA engine and right now, SPI between OP and AHRS is
already using it.

Failures are currently fatal and will lock up the CPU.  This allows
useful information to be obtained in the failure cases.

c8486d08e4 Fixed some bugs in OpenPilot Core.
- syntax error in pios_board_posix.c introduced with Doxygen comment blocks
- platform dependant code had been added to openpilot.c instead of pios_board.c
- redundant header inclusion (stm32... already included by PiOS)

840f7ff456 A version of the firmware that successfully Acks back and forth over HID. Still need to refine the PIOS interface and make GCS strip out the report ID data (if necessary). Also note: currently if you run too many modules the watchdog timer kicks in. I haven't determined if this is due to an interrupt binding up or what (and why it doesn't happen more often since I can't find any code that explicitly resets the WWDG).

- Added FlighSituation Module (development module for sensor fusion, mostly stub, possibly renamed later)
- Added Navigation Module (development module for navigating towards a point in space - DEVELOPMENT CODE, NOT STABLE YET (I am testing around with this)) 
- Changed Stabilization Module (uses local reference frame now. Stable except for code cleanup/review. Tested in simulator and outperforms old code.)

9f2a01a78a Flight/Servo Fix Servo driver buffer overflow, was messing up the I2C and altitude readings, now working fine. Servo index used to be 1-8 but the Servo driver was indexing a buffer out of bounds. Changed everything to use index 0-7 for servo outputs.

17bea4cb91 ahrscomms: connect the OP board to the AHRS board
The AHRS comms module now sync's with the AHRS and
exchanges interesting data periodically.  Whenever
the link to the AHRS is down, the AHRSComms alarm is
raised.

This is fairly basic for now but provides the last
piece of the infrastructure to move data back/forth
between the OP and the AHRS.

a3a2dbd634 spi: Add support for hardware CRC generation/checking
PIOS SPI devices may now make use of automatic CRC generation
and checking on block transfers.  Only supports CRC8 for now.

Since the SPI interface CRC calculation continues across message
boundaries (ie. not reset on every transfer), we must manually reset
the CRC registers for every transfer to allow the two sides of the
link to resynchronize.

Unfortunately, resetting the CRC registers requires disabling the
SPI peripheral which must now be done on every block transfer.

Note: The last byte of the tx buffer is never sent and is assumed to
      be a place holder for the tx CRC8.
Note: The last byte of the rx buffer is expected to hold the rx CRC8.
