用STC15F104E单片机制作闪灯

用STC15F104E单片机，就是一个定时器，上电开始计时，LED每秒闪一次，9小时后继电器吸合3秒，然后释放，计时器重新计时。如此循环。#include "reg51.h"typedef unsigned char BYTE;typedef unsigned int WORD;#define SYSclk 6000000L#define MODE1T        //Timer clock mode, commendt this line is 12T mode, uncomment is 1T mode#ifdef MODE1T#define T1MS (65536-SYSclk/1000)        //1ms timer calculation method in 1T mode, 1000=1000Hz#else#define T1MS (65526-SYSclk/12/1000)        //1ms timer calculation method in 12T mode#endifsfr AUXR=0x8e;                    //Auxiliary registersbit TEST_LED=P3^3;sbit relay = P3^4;WORD count;                        //1000 times counterBYTE sec;BYTE min;BYTE hour;BYTE S3cnt;BYTE S3cnt_Stat;void clock_cnt();/*Timer0 interrupt routine */void tm0_isr() interrupt 1 using 1{    if (count--==0)    {         count=500;            //500ms         TEST_LED=!TEST_LED;        if (TEST_LED) clock_cnt();    }}void main(){#ifdef MODE1T    AUXR=0x80;         //timer0 work in 1T mode#endif    TMOD=0x00;        //set timer0 as mode0 (16-bit auto-reload)    TL0=T1MS;        //initial timer0 low byte    TH0=T1MS>>8;    //initial timer0 high byte    TR0=1;            //timer0 start running    ET0=1;            //enable timer0 interrupt    EA=1;            //open global interrupt switch    sec  = 0;    min  = 0;     hour = 0;    S3cnt_Stat = 0;    while(1);}void clock_cnt(){    if (S3cnt_Stat)    {        S3cnt--;        if (S3cnt==0)         {            S3cnt_Stat = 0;            relay = 0;      //继电器释放        }    }    else    {      sec++;     if (sec>=60)     {         sec=0;        min++;        if (min>=60);        {            min=0;            hour++;            if (hour>=9)         //到了9小时            {                relay = 1;        //继电器吸合                sec = 0;                min = 0;                hour = 0;                S3cnt_Stat = 1;                S3cnt = 3;        //计数3秒            }        }     }    }}
