Available languages: 🇧🇷, 🇺🇸

Building the project

If you don't have the pico-sdk downloaded start by running the following commands (don't forget to replace <PATH-TO-PICO-SDK> with your actual SDK path):

$ git clone https://github.com/raspberrypi/pico-sdk.git --branch master
$ cd pico-sdk
$ git submodule update --init
$ cd ..
$ export PICO_SDK_PATH=<PATH-TO-PICO-SDK>

Then, run the following commands to download and build the project

$ git clone https://github.com/LucasCalcada/PicoMIDIKeyboard
$ cd PicoMIDIKeyboard
$ mkdir build
$ cd build
$ cmake ..
$ make

Finally, plug in the pico holding the BOOTSEL button and copy the MIDIKeyboard.uf2 file into the board's storage

Installation

You can download a prebuilt version on the releases section (It is recommended to build the project yourself, since you can customize the settings to your likings and needs)
The firmware can be installed by holding the pico's BOOTSEL button and copying the MIDIKeyboard.uf2 file into the board's storage

Configuration

By editing the midi_config.h you can customize the funcionality of the keyboard
