I have reverse engineered the protocol of Fender's foot switch (MS-4) and expression pedals (EXP-1). I wanted to be able to control my own amp (in the making) with these, so I thought I might use what I already have and figure out how to talk to these.

I've posted the protocol description and a sample program running on an AVR128DA48 Curiosity Nano dev board to github:

Any suggestions or comments are welcome!
