Would it be possible to use two pi Picos as a Midi bridge between two host devices? #1

Hello there! First of all, thank you so much for the project.

My intention is to get two RPi 3s communicating via USB-Midi. I am aware that there are devices which function as a bridge to allow two hosts to connect, and I wondered if it would simply be a case of having two Picos with the UART Tx Rx pins connected. Would that be correct?

Many thanks!

Yes, this should work. You have to cross-connect the UART-TX/-RX lines and connect GND of both Picos. The power pins (VSYS, VBUS) must NOT be connected, because the Picos will be powered via USB. Thanks for appreciating my project!

Thank you so much for such a prompt reply!
I shall test it and let you know the results. All the best

@ramphands Did this work for you?

Irritatingly I haven't been able to find a second Pi Pico so I haven't had a chance to test it yet.

Understood. Thanks for info.

However, I must add that I've been using the code for the one Pico that I do have, interfacing between a RPi3 (outputting USBMidi) and another RPi3 running Minidexed (using the UART pins) and it's working wonderfully.

Good to know. Thanks!

Seeing as I still haven't been able to get another Pico, I ended up creating a hat/shield for the Pi with your code-laden Pico attached. Actually works out more elegantly than I would have thought! https://github.com/ramphands/Minidexed-Shield Thank you again so much for the code - it works like a charm.

You are welcome. Your shield looks great!
