# Operating System

## [freeRTOS](https://www.freertos.org/)

Is a real-time operating system kernel for embedded devices that has been ported to 35 microcontrollers. It is distributed under the MIT License.

FreeRTOS is designed to be small and simple. The kernel itself consists of only three C files. To make the code readable, easy to port, and maintainable, it is written mostly in C, but there are a few assembly functions included where needed (mostly in architecture-specific scheduler routines).

FreeRTOS provides methods for multiple threads or tasks, mutexes, semaphores and software timers. A tick-less mode is provided for low power applications. Thread priorities are supported. FreeRTOS applications can be completely statically allocated.
