Description TBD.
The code depends on the Raspberry Pi Pico SDK, which is added as a submodule. To checkout the SDK and other submodules do:
git clone https://github.com/arturo182/AyoOS
cd AyoOS
git submodule update --init --recursive
Building the code is quite easy:
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Debug ..
make
