介绍一种数字微波设备监控系统的设计,分析μC/OS-II在该系统中的具体应用。根据实际需求把应用程序划分为可独立运行的多个任务,并讨论了任务的创建、优先级的设置以及如何调度。在此基础上,对中断机制和堆栈的设置进行了研究,针对应用中遇到的问题给出相应的解决方案,μC/OS-II的使用提高了系统的实时性和稳定性。 This paper introduces the design of a digital microwave equipment monitoring system and analyzes the application of μC / OS-II in this system. According to the actual needs of the application can be divided into multiple tasks can run independently, and discussed the creation of the task, the priority setting and how to schedule. On this basis, the interrupt mechanism and stack settings are studied, and the corresponding solutions are given to the problems encountered in the application. The use of μC / OS-II improves the real-time and stability of the system.
