The Core Role of the FreeRTOS Idle Task Maintaining Minimum System Operation Guarantee Automatically created after the scheduler starts, with the lowest priority (usually 0), ensuring that there is always a task for the system to execute. When all user tasks are blocked or suspended, the idle task takes over the CPU to avoid an … Read more
