各位仁兄好！，我想用宏晶STC89C52RC自带的E2PROM保存新的定时时间值，使掉电后再接通电源能正常执行原来设定的定时时间，无需再重新设定。以下是我借鉴了别人的一些程序编写的51定时器插座C程序，我把E2PROM相关的读写程序写进去了，由于初学单片机，看了很多例程，还是一头雾水，故请教各位仁兄，需要设定什么变量，在什么地方添加什么代码可完成此项功能设计，以下是我的51定时器插座代码，谢谢指导！！！ 【我的定时器实现的功能之一是：比如每天8:00——12：00、14:00——18:00插座接通电源其余时间断开插座电源。如果停电了，等来电时，定时器无需再次设定定时时间，它能自动执行先前设定的定时时间8:00——12：00、14:00——18:00接通电源，使之具有定时掉电记忆功能】，现在是掉电再开机，自动恢复初始设定时间。还望大家耐心指导！
