摘要
本文根据目前测控系统中对时间控制的需要,结合实时时钟芯片的类型、特点和实时应用测控电路,详细介绍了DS12C887的定时、闹钟和方波输出等三种功能及其在单片机控制测试系统中的具体应用和注意事项。
At present time-controlling is used extensively in most of application system,this paper discusses the timing, alarm clock and the square wave exporting functions of DS12C887 combining with the type and the characteristic of the RTC(real time clock)chip and the applicative circuit. And also introduces the typical applications and notices of RTC DS12C887 in the control and test system for SCM.
