Important note

This repository is a fork from STM32Duino archive.

I'm working on the implementation of the STM8L151F2 because I got a bunch of those chips.

Arduino core support for STM8 based boards

Introduction

This repo adds the support of STM8 architecture in Arduino IDE.

This porting is based on several external components :

• STMicroelectronics Standard Peripheral Libraries (SPL)
  • SPL for STM8L
  • SPL for STM8S
• Cosmic compiler, allowing to compile c++ source code on stm8 family (http://www.cosmic-software.com/)

Solution is running on Windows only.

Getting Started

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

"Standalone" chip core

• STM8L151F2

Boards available

• STM8L

  • Nucleo STM8L152R8

• STM8S

  • Nucleo STM8S208RB

Troubleshooting and known issues

Please note that this is a new core using a new compiler. You may face some issues with libraries compatibility.
We have several known issues :

• Windows 10: Board binary may be corrupted when plugged on a Windows 10 machine. To ensure compatibility with Windows 10, please upgrade STLink with revision 2.32.22 or higher (estimated availability October 1st).
• Endianness: STM8 microcontrollers are natively Big Endian whereas Arduino boards and STM32 microcontrollers are Little Endian. By default, some libraries don't handle endianess, therefore these won't be directly compatible with STM8 (this is the case of SD library for example).

If you have a question about compiler, you can also send a mail to Cosmic support : send a mail to Cosmic support
