Been feeling pretty terrible the last couple of days, so decided to put those crimps that arrived yesterday to good use. This will eventually be my take on the Super Simple MIDI Keyboard, but for now the buttons just illuminate the onboard LED on pin twenty five.
I have also implemented note on and note off MIDI commands, but have no way to test that they’re being sent on UART TX0 (pin GP0). Hopefully the mail person will bring me a MIDI cable and chassis mount in the next few days.
