Drumkit

Quick Start

Initialize your local repo and prepare the build:

git clone https://git.xythobuz.de/thomas/drumkit.git
cd drumkit
git submodule update --init
cd pico-sdk
git submodule update --init
cd ..
mkdir build
cd build
cmake ..
cd ..

Then you can build new binaries like this:

make -Cbuild -j4

Flash as usual using the mass storage bootloader of RP2040.
