用51单片机做的电子时钟

用51单片机做的电子时钟程序如下：#includeunsigned char codetable1[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f ,0x40,0x76};//字码表0-9,最后一个是一横"-"unsigned int i,a,b,c,d,flag,flag1;unsigned int sec,min,h,nm,nh,nz;unsigned int w,day,mon,year;int miao1,miao2,miao3;sbit keyled=P1^0;sbit key2=P1^1;sbit keyinc=P1^2;
