This project is intended as a starting point for working with the Pico SDK and Pimoroni Libraries in C++.
It's easier if you make a pico
directory or similar in which you keep the SDK, Pimoroni Libraries and your projects alongside each other. This makes it easier to include libraries.
Also the SDK does not support current gcc versions therfore you need to change pico-sdk/cmake/preload/toolchains/pico_arm_gcc.cmake to:
set(ARM_TOOLCHAIN_COMMON_FLAGS " -mtune=cortex-m0plus -march=armv6-m -mthumb")
are installed as a submodule
