多功能电子钟设计

只看该作者 · 2012-3-19 11:18

下面的程序是在学习中断和定时器时写的,已调试通过,
多功能电子钟有如下功能:
1,可以用来做电子钟
2,可以用做报警器(按P3.2时,用做报警)
3,可以用做闹钟(按P1.6时,用做闹钟)
4,可以显示星期
程度当中还有好多的不妥之处,还请高手门帮忙指正.
程序如下:
内容如下:
#include <AT89X51.H>
#define uchar unsigned char
#define uint unsigned int
uchar code dispcode[]={0x81,0x9f,0xa4,0x8c,0x9a,0xc8,0xc0,0x9d,0x80,0x88};
uchar code DATA[]={0xfc,0x92,0x98,0xac,0x89,0x01,0x5c,0x80,0x88};
uchar dispbitcode[]={0xfe,0xfd,0xfb,0xf7};
uchar dispbuf[8]={0,0,0,0};
uchar dispbitcnt;
uchar second,minite,hour,day;
uchar clockhour,clockminite;
uint tcnt;
uchar mstcnt;
uchar t;
uint a;
//上面的是定义各个变量和数码管缓存
void yanshi(uint t)
{
for(;t>0;t--);
}//延时子程序
void beep()
{
while(hour<clockhour){
for(a=0;a<1000;a++)
{yanshi(5);
P1_4=~P1_4;}
for(a=0;a<1000;a++)
{yanshi(5);
P1_4=~P1_4;}
for(a=0;a<5000;a++)
{yanshi(6);
P1_4=~P1_4;}
if(P3_6==0){break;}}
while(minite<clockminite){
for(a=0;a<1000;a++)
{yanshi(5);
P1_4=~P1_4;}

P1_4=~P1_4;}
for(a=0;a<5000;a++)
