preface Taking time to study and compare several RTOS, such as RT thread, FreeRTOS, LiteOS, etc., we found that LiteOS is also quite good. So download the source code, view the documents, configure the development environment, and start the learning journey of LiteOS.   Environment construction The development of embedded software requires ...

1. Purpose of task priority table The priority table is used to indicate whether there are ready tasks under the corresponding priority. The operating system kernel always selects the task execution from the highest priority in the priority table, and the ready table is dynamically updated. For example, let's understand the task priority table ...

preface Using semaphores can complete the synchronization between tasks, but using semaphores to synchronize tasks can only synchronize with a single event or task. Sometimes a task may need to be synchronized with multiple events or tasks, and the semaphore is powerless. FreeRTOS provides an optional solution for this, which is the event ...
