Introduction to FreeRTOS: Basics of Semaphores

SemaphoreWe all know about queues, which can be used to transmit different types of data.However, sometimes we only need to convey a state without transmitting specific information.Thus, we introduce semaphores, which do not transmit data but rather convey states, serving as notifications and saving memory. A semaphore cannot transmit data; it only has a count … Read more
