Official FreeRTOS Ports


Don't see an exact match for your microcontroller part number and compiler vendor choice? These demos can be adapted to any microcontroller within a supported microcontroller family. See the Creating a new FreeRTOS application and Adapting a FreeRTOS Demo documentation pages. As many IDEs are now based on Eclipse, also see the page that describes how to use virtual and linked paths in the Eclipse project explorer to ensure you do not need to copy the RTOS source files into an Eclipse project directory.


FreeRTOS ports are categorised as either being officially supported, or contributed. The Official and Contributed Definitions page describes the categories, and the rationale for making the distinction. This page only lists the official RTOS ports:
