RTOS in 5 Days

Free 5-day RTOS course. Real-time concepts, FreeRTOS, tasks, queues, semaphores, and timing guarantees.

  • Understand what makes a system real-time: deadlines, determinism, and scheduling
  • Create FreeRTOS tasks, set priorities, and understand preemptive scheduling
  • Use queues for inter-task communication and semaphores for synchronization
  • Use mutexes to protect shared resources and avoid priority inversion
  • Implement software timers and profile task timing with FreeRTOS trace tools
