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 lightweight, optimized, expert-oriented set of APIs designed for both performance and runtime efficiency. CMSIS device definition for STM32. Arduino.cc IDE allows to add easily new board thanks the "Boards Managers". More information about...
