Re: [GUIDE] Direct MIDI IO for ST and Amiga Cores

You may want to contact Nat from https://misterfpga.co.uk. He wanted to build a few. Personally, I'm not a seller and don't plan to be. So I don't want to deal with declaration forms and whatnot. It's just not fun for me ;-) All good! I ordered 5 bare pcbs - thanks for sharing the design! PS: If anyone wants a bare pcb or a built one I will have t...

Re: [GUIDE] Direct MIDI IO for ST and Amiga Cores

Just realized I have never posted my DIY midi pcb in this forum: https://github.com/bzeiss/mister-pcbs/wiki/Midi-PCB Ah nice - you made one with the same footprint as the nano :) Do you have any spare raw pcbs available please? Are you in the EU? I have a few, but at some point, I want to add jlcpcb assembly files for the smd parts of the board. T...

I had an arduino midi shield lying around so lashed that up for testing!

The optoisolator is connected to the shield_5V pin and so this must be wired to the nano_3V3 header to avoid over-voltage on the fpga.

JP7_1 = Rx
JP7_2 = Tx

I haven't seen the schematic but I imagine there's a buffer and opto-isolator on the MIDI breakout board, so I doubt you can break it
