问 这个数字钟是用数码管显示,用二个键来控制时间的设置.
但是不知道其优差,请高手指点交流.
还有我想呼吁网上的朋友们把真的程序(没有错误,可以应用的)
贴上来,这样更有利于交流.

程序如下:#include<reg52.h>
#include<intrins.h>
unsigned char code seg[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x98,0xff};
unsigned char led[6];
unsigned int k,m,w;
unsigned char i,j,flash_wei=0xff;
struct time{           
         unsigned char sec;
          unsigned char min;
          unsigned char hour;
           };
struct time clock;
sbit P26=P2^6;
sbit P27=P2^7;
bit flash=1;
bit keypress=0;
bit en_fresh=0;


fresh_led()
{led[0]=clock.sec%10;

en_fresh=0;
}

void display()    //显示函数
{
if((flash_wei==j)&&(!flash))
   P1=seg[10];

P1=seg[led[j]];

   答 1: 你的程序注释太少,看起来太累发原理图和源程序给我吧,我的邮箱:daniel_wind@163.com,只能在晚上才能看到邮件.
