Counting semaphores and mutexes can be used to provide mutual exclusion. However, mutexes should be used only for mutual exclusion, while counting semaphores are more versatile because they can also be used for event notification and thread synchronization. A mutex is exceptionally robust in providing...

Before using a counting semaphore, we must first create it using FreeRTOS API. Like xSemaphoreCreateBinary(), xSemaphoreCreateCounting() API function is used to create counting semaphores. Also, the same function is used for event counting and resource management. Only the way we use input arg...
