A Raspberry Pi Pico MIDI Player, written in MicroPython.
This is a somewhat dysfunctional MIDI player for a Raspberry Pi Pico. TL;DR, it allows you to take MIDI files, and shove them down your Raspberry Pi Pico's GPIO pins as PWM signals.
-
Download the source code and extract it's contents onto your Raspberry Pi Pico. Make sure that it's running MicroPython first. I would recommend using Thonny.
-
Download a MIDI file (No more than 4 voices)!
-
Shove your MIDI file into this converter and add your song data in songs.py. Recommended default settings are
.\miditones.exe -t=4 .\your-midi-here.mid -
See main.py for the rest!
GPIO Pins 6-9 are used by default.
- 6 -> Channel A0
- 7 -> Channel A1
- 8 -> Channel B0
- 9 -> Channel B1
Of course, since the Raspberry Pi Pico's pins are almost entirely PWM-friendly, you can remap this to whatever pins you want in rpmidi.py (as long as they are PWM supported, which should'nt be a problem).
| Version | Info |
|---|---|
| v1.1 | Timing bug fix and code cleanliness fixes. |
| v1.0 | Initial commit. |
- If MIDI files have more than 4 voices, the MIDI timing will get borked.
- TODO: find more bugs
Thanks to LenShustek for providing the Miditones converter, evilwombat for the stm-bmc project (Mainly inspiration for the default music), and the Raspberry Pi Foundation for creating the Raspberry Pi Pico!
