FreeRTOS provides various communication mechanisms for inter-task communication, including queues, semaphores, mutexes, event groups, and task notifications. Below is a detailed introduction to queues.Queues Queues support asynchronous data transfer between tasks and between tasks and ISRs. They can transfer any type of data and support multiple tasks sending data to the same queue, as well … Read more
