What is haxo-ino?

haxo-ino is an Arduino/C++ port of haxo-rs by @cardonabits to run the Haxophone. It is narrower in scope than haxo-rs in that its only goal is send MIDI commands out over USB to a host device; there is no audio being sent to the Haxophone's 3.5mm headphone jack. Since the system runs on a microcontroller, the MIDI controller is ready ~2 seconds after being plugged in, rather than the ~2 minutes needed to start the system up the Pi Zero.

What Do I Need?

• A Waveshare RP2040-PiZero (Amazon link), which is nearly pin-to-pin compatible with the standard Raspberry Pi GPIO setup.
• USB Type C cable
• Arduino IDE
• A host device to play music through

How To

• git clone this repo

• Install the following:
  • Boards Manager
    • Raspberry Pi Pico/RP2040 by Earle Philhower
  • Libraries
    • MIDI Library by Francois Best
    • Adafruit TinyUSB Library
