Yes, we do actually want I2C to run fast.

Bye bye Wii Motion Plus, hello MPU6050. Also, increase control loop
...
to 200Hz, add SD card logging, and a number of other changes.

Firmware changes to match rewired control board.
...
This is a bit more difficult than just reassigning pins as the usage
of the timers has changed to the point of using 16 bit timers where 32 bit
timers would have been ideal. This makes the use of the prescaler necessary,
and we need to cope with a different prescaler value being used on different
timers.

Implement CPPM reception. Keep it as an option for now.
...
Recalibrate the radio, as the timings have changed.
And, it seems a couple of channels are now swapped with the new radio. Or
rather, unswapped. So fix the channel map to match.

Oh, and code to make the calibration easier/possible.

Improve handling of arming, providing LED blink codes if the arming fails.
...
Also, implement a software watchdog to make sure that the main real-time
modules are actually being run. Provide a panic facility, also giving blink
codes to indicate the panic reason.

loops, boot-time initialisation, option to run without attached UART.

Track gyro using a DCM.
...
This brings in an implementation of some general matrix manipulation routines,
not all of which are used at teh moment.
Output the DCM on the UART at 50Hz for the host to display it usefully.
