Two full days of learning embedded C toolchains to build a blinky without STM32CubeIDE and my head is spinning but my blinky is flashing 😅 #embedded #electronics #programming tldr - gen. makefile and HAL code with CubeMX - download local versions of arm-none-eabi-gcc (dl via website) + make (homebrew) + openOCD (homebrew) - edit Makefile and some VScode plugin configs for Intellisense include paths This video ended up being the way to go: https://www.youtube.com/watch?v=PxQw5_7yI8Q
