[REQUEST] GPIO MIDI Interface #9

Closed duduke closed 4 years ago

duduke commented 4 years ago

Can the GPIO Interface on the RPi be used as a midi device? Something like this:

Thanks.

It can! I was actually using a GPIO interface when I first started experimenting.

However, I had lots of problems with missing notes/packets, so I need to give this another go and see what was wrong. I'll add the GPIO code back in shortly.

This should be working in the latest build - I also updated the README with schematic and breadboard examples.

Thanks!

Dang that was fast :)
