This repo adds the support of STM32 MCU in Arduino IDE.

This porting is based on:

• STM32Cube MCU Packages including:
  • The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls
  • The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
  • CMSIS device defintion for STM32
• CMSIS: Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex®-M processor series and defines generic tool interfaces. It has been packaged as a module for Arduino IDE: https://github.com/stm32duino/ArduinoModule-CMSIS
• GNU Arm Embedded Toolchain: Arm Embedded GCC compiler, libraries and other GNU tools necessary for bare-metal software development on devices based on the Arm Cortex-M. Packages are provided thanks The xPack GNU Arm Embedded GCC: https://github.com/xpack-dev-tools/arm-none-eabi-gcc-xpack

This repo is available as a package usable with Arduino Boards Manager.

If you have any issue, you could file an issue on Github.

For question, support, ..., you could submit a topic on the stm32duino forum:

In any case, it always fine to search if your issue was not already existing before submit a new one.
