Adding 5-pin DIN MIDI input

OWL
#1

I’ve seen people ask questions about hardware modifications on here. Has anybody experimented with adding a 5-pin DIN MIDI input? Would that be possible?

There is a serial interface available which is capable of both in and out MIDI. For MIDI input you will need an opto-coupler, for the output I think all you need is a series resistor and connector.
Is this for the OWL Pedal or Modular?

It’s for the pedal. Would I also need to change/add code to the firmware?

Also interested, owl modular in my case. I’ve built din midi connectors for arduinos before. That part is easy, but what about the software part??

Yes, firmware changes would be required!
It should be possible to piggyback on the existing usb midi implementation.

That’s super awesome news! Do you by chance have the name of the serial interface and where it can be purchased? For the opto-coupler as well? I’m mostly just interested in the MIDI input.

Hi,

for the hardware part, this is a thorough explanation MIDI Tutorial - learn.sparkfun.com

of course you need to know where to connect to the OWL as well…

for the software part, I haven’t got a clue :slight_smile: hopefully as simple as an extra instance of the MIDI Class? anyone?

I will build this as soon as that part is somewhat clear…
