FreeRTOS Kernel

FreeRTOS is a lightweight, open-source real-time operating system for microcontrollers. It provides task scheduling, inter-task communication (queues, semaphores, mutexes), timers, and memory management. Developers write multiple tasks that run concurrently; the FreeRTOS scheduler decides which task runs when. Used in IoT devices, industrial controllers, automotive systems (Tesla, Ford), and medical devices. Over 100 billion devices run FreeRTOS.
