RTOS Concepts
Tasks, priorities and deadlines in embedded systems.
How it works
FreeRTOS and Zephyr provide preemptive priority scheduling, tasks, queues, semaphores, mutexes and timers with bounded latency on MCUs.
Where it is used
Systems with multiple concurrent activities.
Common pitfall
Priority inversion and stack sizing per task.
