My goal is to read various input devices ie joystick, keyboard, etc. encode the
data into some sort of bit or ascii stream and then transmit it to the HB for
decoding and if possible transmit from the HB back to the PC for telemetry such
as position, battery power, etc.

Are you wanting to transmit an analog signal, e.g. faster/slower, such
as most people do with a joystick, or some other purpose? Did you want
the PC to generate the signal, or a standard RC transmitter receiver?
I've used the HB Input Capture line hooked to an RC receiver. It would
capture the pulse-width of the RC comand from my joystick, but no PC was
involved, other than firing up the HB. Worked well, had to have some
interrupt code in assembler, and the HB only has 2 Input Capture lines
available ( the system uses some for the beeper, et.al.), so you can
only do 2 channels (fore/aft and left/right).
