该程序为初学者学习单片机时使用的60S倒计时程序，可将开程序用在proteus软件上进行仿真，我试过可行的~(The program for beginners to learn the use of single-chip microcomputer of the 60S countdown procedures, can be used in open procedures proteus simulation software, I tried to possible ~)

这是一份控制方法的C语言实现文档，写的非常好，分享给大家，特别是PID算法，说的还蛮好的(This is a method of controlling the C language document, written in a very good, for everyone to share, particularly in the PID algorithm, that s quite good)

对于闭环控制有很好的说明以及pid算法的具体实现(Specific implementation for closed-loop control has a good explanation and pid algorithm)
