A simple Raspberry Pi Pico based midi controller that uses the Pico-SDK to make a simple midi controller that reads a button and sends out a midi note when that button is pressed.
The project includes a simple Debounce library that will debounce the button presses to remove jitter.
It expects the button to be connected to pin 1 (GP0) and pin3 (GND) but you can change this in the code.
The project also includes a simple SuperCollider script set up to receive midi notes from this controller and play a synth accordingly.
- TinyUSB setup ready to use
– Preconfigured libraries automatically included with this project:
- PicoDebounceButton – allowing to do debounced button reads
- PicoResponsiveAnalogRead – make analog readings of potentiometers etc. less noisy
- PicoOSC - Send/Receive OSC communication (WORK IN PROGRESS)
- Use CPM as an automatic package manager, simply run the cmake config step and it will download dependencies
- A Github Action to automatically build the firmware and release it on your repo. All you need to do is add a git tag prefixed with
vand push it, eg.git tag v0.1.0 && git push --tags
Before building, you need to clone the pico sdk to your computer somewhere, eg:
git clone https://github.com/raspberrypi/pico-sdk $HOME/pico-sdkThen build the project:
# Change path to pico sdk if you cloned it somewhere else
export PICO_SDK_PATH=$HOME/pico-sdk; cmake -B build -G Ninja
cmake --build build
