Mutex Issues Between RTOS Tasks

When developing projects based on RTOS, we often encounter mutual exclusion situations, such as: multiple tasks needing to use a single UART port to send data. If mutex locks are not used, a higher priority task may preempt the UART and send data, potentially resulting in “garbled” data being sent. Today, we will discuss a … Read more
