# Generic STM32 HAL based on the stm32duino core
This HAL is intended to act as the generic STM32 HAL for all STM32 chips (The whole F, H and L family).
Currently it supports:
* STM32F0xx
* STM32F1xx
* STM32F4xx
* STM32F7xx
Targeting the official [Arduino STM32 Core](https://github.com/stm32duino/Arduino_Core_STM32).
