关于12864制作一个秒表程序

初学者编写,谢谢各位

12864应用实例-秒表

12864是一块128*64的图形显示液晶，在单片机学习领域有着极为广泛的应用，在这里对12864的图形取模， 以及程序编写进行一个51单片机的初步示范，程序为本人借鉴各位网络大神的程序自行综合编写的，如有雷同，呵呵…….

首先是图形函数取模部分：

1. 打开取模软件ZIMO21

2. 打开一张图片，注意图片的格式需为128*64点阵，BMP单色位图格式，可以先用画图程序对图片进行编辑。

3.设置参数：取模方式为C51。

初学者编写,谢谢各位

将取出的代码保存，并且复制到程序的“请输入图形代码” 函数内部。

4.示范程序：

#include<reg52.h> //载入52单片机函数库

#include<intrins.h> //载入位移动函数库

#define uint unsigned int //定义int

#define uchar unsigned char //定义char

#define lcddata P0 //定义端口

sbit rs=P3^5; //数据/命令选择端

sbit rw=P3^6; //读/写 选择端

sbit e=P3^4; //使能信号

sbit busy=P0^7; //忙时检测

uchar code dis1[]={"00"};

uchar code end[]={"时间结束"};

uchar code end2[]={"TIME OVER"};

//uchar code dis1[]={"1234567890"};

uchar code tab[]= //此处请输入图形代码

{
