This project uses the the Raspberry Pi Pico SDK and it uses the tinyusb library for the USB stack. Picoprobe GP5/UART1 RX -> MIDI Pico GP0/UART0 TX Picoprobe GP4/UART1 TX -> MIDI Pico GP1/UART0 RX If you choose to use the same hardware I did, wire the boards together as follows. Note that just using the adapter provides no current limit on the USB host VBus line, so please be

I use the least expensive micro USB to full size USB A OTG adapter I could find. If you use the Pico board, you will need to be able to connect your USB MIDI device to the Pico's micro USB connector. I use the VBUS pin from a picoprobe board. You will need to provide +5VDC to the VBus input. Also note there are noįerrite beads on MIDI IN and MIDI OUT connector pins, so radio frequency interference (RFI) may be Note that MIDI OUT is not isolated from your processor board UART 1 TX pin. You would like for the current loop driver for MIDI OUTĪnd the optical isolator for MIDI IN. The project uses the RP2040 UART 1 port for driving the old school MIDI IN and MIDI OUT ports. It is tested on aīut any board that provides access to the USB port and UART 1 will probably be fine. This project is designed to run on the RP2040 chip. The hardware combinations described here would almost certainly fail electrical and RFĬompliance testing. A carefully designed custom board would be a better Not been paid by anyone to use this hardware. I do not officially endorse any hardware. This projects uses commercial hardware for testing. I will take no responsibilityįor burning up your favorite keyboard or sound module.

Your circuit and wiring before you connect it to anything expensive. The MIDI gadgets you will wire to this hardware will likelyĬost a lot more than than the hardware for this project. Use a Raspbery Pi Pico to add old school MIDI IN and MIDI OUT to MIDI devices with a USB B device port Disclaimers
