使用stm32F103芯片，在最小系统上实现了UCOS-II的完成功能，使用keil4编写；功能包括任务调度，消息队列，信号量集和软件定时等。本人亲测可以直接使用，使用的是标准32库函数(Using stm32F103 chip, the completion function of UCOS-II is realized on the smallest system, which is written by keil4. Functions include task scheduling, message queue, semaphore set and software timing. My pro test can be used directly, using the standard 32 library function)
