FreeRTOS is a real-time operating system for embedded systems. On MCUs based on ARM Cortex-M cores a standardised API exists which is known as CMSIS RTOS. This API is built on top of FreeRTOS. Two different versions of CMSIS RTOS exists: v1 and v2. Except from the queue handling they are almost identical.

STM32CubeMX includes an option to use FreeRTOS. In an earlier life, I did quite a lot of development on ESP32, and that, due to it's dual-core design, is very much centred around FreeRTOS. Back the, I grew to hate FreeRTOS.

The examples on this page is using a STM32F411 based Black Pill development board.
