WebA real-time operating system (RTOS) adds another level of complexity on top of this. Concepts. Volatile memory (e.g. RAM) in most microcontroller systems is divided up into 3 sections: static, stack, and heap. Static memory is used for storing global variables and variables designated as “static” in code (they persist between function calls). WebWhen you create a task in FreeRTOS (e.g. with xTaskCreate ()), the operating system will allocate a section of heap memory for the task. One part of that allocated memory is the …

WebJun 29, 2024 · Dynamic Memory Management. FreeRTOS uses a region of memory called Heap (into the RAM) to allocate memory for tasks, queues, timers, semaphores, mutexes and when dynamically creating variables.
