μC/OS-II 2.0版以上的内核都具有可抢占的实时多任务调度功能，另外它还提供了许多系统服务，例如信号量、消息队列、邮箱、内存管理、时间函数等，这些功能可以根据不同的需求进行裁减。可以说，μC/OS-II是一个具备现代操作系统特点的RTOS，同时它结构清晰、注解详尽，具有良好的可扩展性和可移植性，被广泛地应用于各种架构的微处理器上。 -μC/OS-II version 2.0 kernel over a preemptive real-time multi-task scheduling functions, and it also provides a number of system services, such as semaphores, message queues, mailboxes, memory management, a function of time, etc., these functions can bethe needs of different cuts. It can be said, a μC/OS-II RTOS with a modern operating system features, while it is clear, detailed annotations, has good scalability and portability, are widely used in a variety of microprocessor architecture .
