【单片机定时器程序设计谁有啊】
文章插图
这个是让单片机倒计时60秒的一个程序，用数码管显示#include
#define uchar unsigned char#define uint unsigned intsbit dula=P2^6;sbit wela=P2^7;sbit led1=P1^0;uchar code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};void delayms(uint);void display(uchar,uchar);uchar num,num1,num2,shi,ge;void main(){ TMOD=0x11; TH0=(65536-45872)/256; TL0=(65536-45872)/256; TH1=(65536-45872)/256; TL1=(65536-45872)/256; EA=1; ET0=1; ET1=1; TR0=1; TR1=1; while(1) {display(shi,ge); }}void display(uchar shi,uchar ge){ dula=1; P0=table[shi]; dula=0; P0=0xff; wela=1; P0=0xfe; wela=0; delayms(5); dula=1; P0=table[ge]; dula=0; P0=0xff; wela=1; P0=0xfd; wela=0; delayms(5);}void delayms(uint xms){ uint i,j; for(i=xms;i>0;i--)for(j=110;j>0;j--);}void T0_time() interrupt 1{ TH0=(65536-45872)/256; TL0=(65536-45872)/256; num1++; if(num==4) {num1=0;led1=~led1; } }void T1_time()interrupt 3{ TH1=(65536-45872)/256; TL1=(65536-45872)/256; num2++; if(num2==20) {num2=0;num++;if(num==60)num=0;shi=num/10;ge=num%10; }}
