So, the way this goes is I post my AVR  code, then I post what the HTC Vive does.

The output is:  POST 0: (# of bytes) (IMU Timecode MSBs) (All raw light data)

(All raw light data ends with [3 bytes, LSB timecode] [OTA CRC (probably ignore)])

Events (TIME): (LED CODE 1)/(TIME CODE 1/TIMECODE 2)/(LED CODE 2)/(TIME CODE 3/TIMECODE 4)...
//NOTICE: The funky encoding of the numbers, and the fact that paramters are read from the end of the data going forward.
//We know we're done when the # of parameters read is (# of bytes left*2)-1
