I've been toying with the idea of using a Macropad to run the Arduino CW Keyer sketch from K3NG as an all-in-one portable CW keyer. I am not sure if the RP2040 is compatible with code intended to run on an UNO, I realize the I/O connections would need to be re-mapped to match the RP2040. Before I dive in, Does anyone else think this would be feasible to try?
I have little to no experience with writing code, so this will be an interesting undertaking (to say the least). But, if it would work, it would be a neat project.
Thanks,
Terry
