Distributed freely under the MIT open source license, FreeRTOS includes a kernel and a growing set of libraries suitable for use across all industry sectors. FreeRTOS is built with an emphasis on reliability and ease of use.
FreeRTOS can be thought of as a thread library rather than an operating system, although command line interface and POSIX-like input/output (I/O) abstraction are available.
Developed in partnership with the world's leading chip companies over a 15-year period, and now downloaded every 170 seconds, FreeRTOS is a market-leading real-time operating system (RTOS) for microcontrollers and small microprocessors.
Started as Git clone of FreeRTOS SourceForge SVN repo. Submodules the kernel. Featured FreeRTOS IoT Integration targeting an Arm Corstone-3xx platform based on Arm Cortex-M MCU. FreeRTOS kernel files only, submoduled into https://github.com/FreeRTOS/FreeRTOS and various other repos. FreeRTOS-Plus-TCP library repository. +TCP files only.
