STM32 ARM-GCC Toolchain w/ GPIO_EXTI example
Prologue I have always wanted to build with an ARM MCU, STM32 was on top of my to-learn list. Happily, not so long ago a respected colleague lent me an STM32 Nucleo board to play with, as usual, it stayed in its box for a while and then I started learning about the STM32 MCU and the toolchain and the capabilities of that great MCU. So in this introductory post, I will discuss how to setup your Linux development environment and your arm-gcc toolchain to start compiling and running code on your STM32 MCU....
