Arduino core support for STM32 based boards

Introduction

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: https://github.com/stm32duino/arm-none-eabi-gcc

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

For full instructions on using the "Boards Manager", see the Getting Started page.

Advanced user can use the repository to benefit from the latest development. See the Using git repository page.

User can add a STM32 based board following this wiki.
