MIDI/Audio Wing


Recommended Posts

Hello Alvie,

Yes everything works great. It uploads correctly and stays upon repowering. The only thing now is that the MIDI out is not working. It seems like its not sending anything at all (control changes, program changes, etc.) even probing the tx line with a oscilloscope shows no sign of activity when attempting to send through that port.


Hey Sal,

So I've been verifying the RetroCade MegaWing design and it turns out I'm having the same problem with MIDI out. I made a mistake with the MIDI out portion of the schematic, to make things work you need to have pin 5 of the MIDI OUT connected to 3.3V instead of 5V.
