分享一個18年做的，定時插座，掉電可以保存上次設置的定時時間，顯示為數碼管顯示，驅動繼電器吸合。附上源程序代碼。

單片機源程序如下:
#include <stdio.h>
#include <Key.h>
#include <Usart.h>
#include <Timer.h>
#include "Led.h"
#include "eeprom.h"

#define  OpenPower  0
#define  ShutPower  1
typedef struct
{
      //小時計數器
char  Hour;
      //分鐘計數器
char  Minute;

//volatile char  Seconds;

}TimeDef;

/*

{
      unsigned int x;
      unsigned int y;
      for(x= 0; x<400;x++)
      for(y= 0;y<2000;y++);
}*/

void main(void)                //主函數

//保存時間數據

//static  int TimVar = 0;
//開始啟動打開電源
SupplyPower = OpenPower;

      //讀取保存的數據
