Commands and examples – verify before use:

set(PICO_BOARD pico CACHE STRING "Board type")

Notes and version constraints

When the RGB LED matrix is fully on (current approx. 350 mA), use a power adapter rated at least 500 mA
Do not touch the RGB LED beads while the matrix is fully illuminated
Keeping the RGB LED matrix fully lit for extended periods causes heat buildup, reducing LED lifespan or causing burnout
Flashing Pico2 firmware from MicroPython may cause the device to become unrecognized; use the firmware provided in the package instead
When using the VS Code extension package, the .pico-sdk environment must be correctly configured, otherwise compilation will fail
CMake files must not contain Chinese characters (including comments), otherwise project import may fail
