This repository contains the FreeRTOS Kernel, a number of supplementary libraries, and a comprehensive set of example applications. Many libraries (including the FreeRTOS kernel) are included as Git submodules from their own Git repositories.
FreeRTOS/Source contains the FreeRTOS kernel source code (submoduled from https://github.com/FreeRTOS/FreeRTOS-Kernel).
FreeRTOS/Demo contains pre-configured example projects that demonstrate the FreeRTOS kernel executing on different hardware platforms and using different compilers.
FreeRTOS-Plus/Source contains source code for additional FreeRTOS component libraries, as well as select partner provided libraries. These subdirectories contain further readme files and links to documentation.
FreeRTOS-Plus/Demo contains pre-configured example projects that demonstrate the FreeRTOS kernel used with the additional FreeRTOS component libraries.
Releases contains older FreeRTOS releases.
FreeRTOS Lab projects are libraries and demos that are fully functional, but may be experimental or undergoing optimizations and refactorization to improve memory usage, modularity, documentation, demo usability, or test coverage.
Most FreeRTOS Lab libraries can be found in the FreeRTOS-Labs repository.
A number of FreeRTOS Lab Demos can be found in the FreeRTOS Github Organization by searching for "Lab" or following this link to the search results.
