Dynamic memory allocation is the process of assigning the memory space during the execution time or the run time. WebMemory for tasks can either be allocated dynamically or statically. Dynamic allocation allows the memory used by the task to be returned by calling vTaskDelete () if the task no longer needs to run (see Chapter 7, The FreeRTOS Scheduler, for details).
