我弄的DS1302+LCD12864基本显示已经出来了，但是我还想加上按键调节时间的功能，请问哪位高手能指点一二的，在此感激不尽啊~~~~~~
下面是我的程序：
#include<reg52.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
uchar second,minute,hour,week,day,month,year;
uchar time[] ={0x12,0x07,0x26,0x08,0x07,0x07,0x04}; //初始时间数组
sbit DS1302_RST = P2^2;
sbit DS1302_IO = P2^3;
sbit DS1302_SCLK = P2^4;
sbit LCD_EN = P2^7;
sbit LCD_RW = P2^6;
sbit LCD_RS = P2^5;
sbit key1=P1^0;
sbit key2=P1^1;
sbit key3=P1^2;
uchar num;
sbit DQ=P1^7;
uchar code dis1[]={" DS1302+LCD12864"};
uchar code dis2[]={" 暑假学习 "};
uchar code year_month_day[] = {" "};
uchar code hour_minute_second[] = {" "};
