怎么写8×8led点阵屏显示数字0－9的程序_CMS教程

这个程序可以循环显示0~9#include<reg51h>#include<intrinsh>#define uchar unsigned char#define uint unsigned intuchar code Table_of_Digits[]={0x00,0x3e,0x41,0x41,0x41,0x3e,0x00,0x00, //00x00,0x00,0x00,0x21,0x7f,0x01,0x00,0x00, //10x00,0x27,0x45,0x45,0x45,0x39,0x00,0x00, //20x00,0x22,0x49,0x49,0x49,0x36,0x00,0x00, //30x00,0x0c,0x14,0x24,0x7f,0x04,0x00,0x00, //40x00,0x72,0x51,0x51,0x51,0x4e,0x00,0x00, //50x00,0x3e,0x49,0x49,0x49,0x26,0x00,0x00, //60x00,0x40,0x40,0x40,0x4f,0x70,0x00,0x00, //70x00,0x36,0x49,0x49,0x49,0x36,0x00,0x00, //80x00,0x32,0x49,0x49,0x49,0x3e,0x00,0x00, //90xff,0x81,0x81,0x81,0x81,0x81,0x81,0xff};uchar code xdat[8]={0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01};uchar code ydat[8]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};uchar i=0,j=0,t=0,Num_Index,key,xi,yi; sbit we1=P1^1;sbit we2=P1^3;//主程序void main(){//P1=0x80;Num_Index=0; //从0 开始显示TMOD=0x01; //T0 方式0TH0=(65536-2000)/256; //2ms 定时TL0=(65536-2000)%256;IE=0x82;key=0;xi=0;yi=0;EX0=1;IT0=1;TR0=1; //启动T0while(1);}//T0 中断函数void ext_int0() interrupt 0{ key++; key&=0x03;}void LED_Screen_Display() interrupt 1{TH0=(65536-2000)/256; //2ms 定时TL0=(65536-2000)%256;switch(key){case 0: P0=0xff; we1=1; P0=~Table_of_Digits[Num_Index8+i]; we1=0; P0=0xff; //输出位码和段码 we2=1; P0=xdat[i]; we2=0; if(++i==8) i=0; //每屏一个数字由8 个字节构成 if(++t==250) //每个数字刷新显示一段时间 { t=0; if(++Num_Index==10) Num_Index=0; //显示下一个数字 } break;case 1: we1=1; P0=~xdat[xi]; we1=0; we2=1; P0=ydat[yi]; we2=0; if(++t==250) //每个数字刷新显示一段时间 { t=0; yi++; if(yi>7){yi=0;xi++;} if(xi>7)xi=0; } break;case 2: we1=1; P0=0x00; we1=0; P0=0xff; //输出位码和段码 we2=1; P0=xdat[i]; we2=0; if(++t==250) //每个数字刷新显示一段时间 { if(++i==8) i=0; //每屏一个数字由8 个字节构成 t=0; } break;default: key=0; i=0; j=0; t=0; xi=0; yi=0; Num_Index=0; we1=1; P0=0xff; we1=0; we2=1; P1=0x80; we2=0; break;}}

这个只能通过调试才能弄出来了给你个简单的实例流动的箭头呵呵
