Development 👾

Start a Linux terminal (on windows, just open the command prompt and type wsl);
Install the build system, running the following command on terminal:

sudo apt update
sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential libstdc++-arm-none-eabi-newlib

Download the repository with it's dependencies:

git clone --recurse-submodules --shallow-submodules https://github.com/juliannojungle/pico-sdk-sdcard-lcd-png.git

Open the project folder in vscode, click on the 'no kit selected' on status bar, select GCC arm-none-eabi build kit, then click on Build (right next to it);

*.uf2 file will be written at build directory. Just copy it to the raspberry pico's usb drive.
