Overview

This is an example FreeRTOS application for boards using some common STM32 microcontrollers. Depending on your board, the LED will probably be on different pins.

I had some trouble finding FreeRTOS examples that didn't use proprietary development platforms or external libraries. So I decided to cobble together a simple example that only uses the GCC toolchain and some device-specific header files provided by the chip's manufacturers.

This barebones example just creates two tasks which toggle a GPIO pin on different timings, to make an on-board LED blink irregularly. I'm hoping it can be a simple introduction to bootstrapping an STM32 FreeRTOS application using a free toolchain, so corrections and suggestions are always appreciated.

Boards

Currently, the STM32F103C8 and STM32F303K8 are supported. Boards with the STM32F103C8 are very cheap, and they have a lot of features. ST also provides affordable 'Nucleo' development boards with a variety of chips including the STM32F303K8.

I'm also hoping to get this working with the simpler F0 and L0 lines.

About

An example FreeRTOS project for STM32 microcontrollers. I'm hoping this can be a simple starting point for learning about using a realtime operating system.
