[Elecraft] K2: KDSP2 - open source questions

[Lyle Johnson]

  The DSPx module hardware does not include an ADC to measure  control 
voltage, but it does have some unused digital I/O pins that could read 
buttons, or perhaps an encoder, if you wrote the code to do it.

There is plenty of unused program memory and lots of available DSP 
horsepower for such things.
