‘壹’ 急救！！！各位兄弟姐妹们谁懂单片机编程啊，帮帮我啊！用单片机编辑一个数字钟的程序啊，要求如下：
给你一个我用液晶屏12864写的程序，一个是功能键，按照顺序按一下是第一位跳动，接下再按就是第二位，一次类推。第二个按键是控制加，第三个按键是控制减，你的数码管和这个很类似，比这个还简单，在这你也没有要求数码管是怎么接的。你可以参考的。
#include<reg52.h>
#include<chushihua.h> //12864的初始化函数；
char gwnian,nian,yue,ri,xq,shi,fen,miao;
sbit DQ =P3^5; //定义DS18B20通信端口
sbit led_en_port = P2^5; /*发光二极管寄存器LE引脚*/
sbit sled_en_port = P3^6; /*数码管寄存器LE引脚*/
