Mutexes: Short for "Mutual Exclusion," these are used to protect shared resources (like a peripheral or a global variable) from being accessed by two tasks at the same time.

Once the scheduler starts, the code inside your main() function after the scheduler call will never execute unless the system runs out of RAM. Why Use FreeRTOS?

Software TimersSoftware timers allow you to execute a function at a specific time in the future or periodically. Unlike hardware timers, these are managed by the FreeRTOS daemon task, making them easy to implement without complex interrupt logic. Memory Management in FreeRTOS freertos tutorial pdf

heap_1: Simplest version; does not allow memory to be freed.

Creating Tasks: You use the xTaskCreate() function to define a task, assign it a stack size, and set its priority. Mutexes: Short for "Mutual Exclusion," these are used

The SchedulerThe scheduler is the "brain" of FreeRTOS. It decides which task should be in the Running state. In a preemptive system, the scheduler will immediately switch to a high-priority task the moment it becomes Ready, even if a lower-priority task is currently running.

Inside your main() function, call xTaskCreate() for each task. Call vTaskStartScheduler(). Software TimersSoftware timers allow you to execute a

Low Footprint: The kernel typically takes up only 6KB to 12KB of ROM.
