单片机C语言该怎么编写时钟程序？

这个是简单的数码管时钟显示如果有需要贺戚，我写过比较完善的1602显示时钟.显示控制年月日等等.#include\x0d\x0asbit Begin=P2^0\x0d\x0asbit Hour=P2^1\x0d\x0asbit Mus=P2^2\x0d\x0asbit End=P2^3\x0d\x0aunsigned char code Tab[]={ 0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,\x0d\x0a0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71,0x40}\x0d\x0aunsigned char code num[]={ 0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f}\x0d\x0aunsigned char Time[]={0,0,16,0,0,16,0,0}\x0d\x0aunsigned char a\x0d\x0aunsigned int x,m,th\x0d\x0avoid init()\x0d\x0a{\x0d\x0a TMOD=0x01\x0d\x0a TH0=(65535/50000)/256\x0d\x0a TL0=(65535/50000)%256\x0d\x0a EA=1\x0d\x0a ET0=1\x0d\x0a TR0=1\x0d\x0a}\x0d\x0avoid delay(unsigned int z) \x0d\x0a{ \x0d\x0a unsigned int x,y\x0d\x0a for(x=zx>0x--)\x0d\x0a for(y=110y>0y--)\x0d\x0a}\x0d\x0aunsigned char keyboard()\x0d\x0a{\x0d\x0a if(Begin==0){\x0d\x0a delay(5)\x0d\x0a if(Begin==0)\x0d\x0a return 1\x0d\x0a }\x0d\x0a if(Hour==0){\x0d\x0a delay(30)\x0d\x0a if(Hour==0)\x0d\x0a return 2\x0d\x0a }\x0d\x0a if(Mus==0)\x0d\x0a return 3\x0d\x0a if(End==0)\x0d\x0a return 4\x0d\x0a}\x0d\x0avoid display()\x0d\x0a{\x0d\x0a unsigned char i for(i=0i=20)\x0d\x0a {\x0d\x0a x++\x0d\x0a m=x\x0d\x0a th=m/3600/判悉/设置禅冲陵小时\x0d\x0a Time[0]=th/10\x0d\x0a Time[1]=th%10\x0d\x0a m=m%3600 Time[2]=16 th=m/60//设置分钟\x0d\x0a Time[3]=th/10\x0d\x0a Time[4]=th%10\x0d\x0a m=m%60 Time[5]=16 th=m//设置秒\x0d\x0a Time[6]=th/10\x0d\x0a Time[7]=th%10 a=0\x0d\x0a }\x0d\x0a}
