匆忙之中做了这个用来抵挡导师的项目库，略有粗糙还请见谅，以后有时间画板子？？不会吧哈哈哈

//LCD1602引脚定义
#define LCDDATA P0
sbit RS = P2^3;
sbit RW = P2^4;
sbit CS = P2^5;
//DS1302引脚定义
sbit RST = P1^2;
sbit DAT = P1^1;
sbit CLK = P1^0;

匆忙之中做出来的这个，有时间画板子加别的功能吧

单片机源程序如下:

#include <reg52.h>
#include "DS1302.h"
#include "LCD1602.h"
/*
*在reg52头文件定义了uchar
//LCD1602引脚定义
#define LCDDATA P0
sbit RS = P2^3;
sbit RW = P2^4;
sbit CS = P2^5;
//DS1302引脚定义
sbit RST = P1^2;
sbit DAT = P1^1;
sbit CLK = P1^0;
