This is a small 'blinky' sample project, implemented using libopencm3 and FreeRTOS, in PlatformIO. It has been tested against a 'bluepill' STM32F103C8T6 using STLINKv2.
Use this sample project as a template for your own libopencm3 + FreeRTOS STM32 projects.
I got this working thanks to:
- the original author of this example code: Warren Gay
- Maximilian Gerhardt from the PlatformIO community
- jacfont upgrading FreeRTOS to 10.4.1
- deltaphi, who fixed the debug build
