在12864液晶上显示任何图像 12864液晶

一，所需软件：

Any to Icon

作用：用来把随意彩图，转化成黑白2色图。

windows画图软件

作用：用来编辑DIY2色图片，并可改属性改成128X64像素

字模提取软件
作用：把128X64像素的图片，生成编程所需要的十六进制代码。

二，自己完全DIY一副图画（就像在一张白纸上画自己想画的），或修改一副2色的BMP图，然后在让它在液晶上显示。

步骤如下：

1，双击打开windows画图软件

2，点击 图像->属性，设置如下，确定



3.点击 查看-> 缩放-> 自定义

选择缩放到600%，确定

4.点击 查看-> 缩放-> 显示网格

5.通过画图工具可在网格内自己写字和画图



6.如果已有一幅2色的BMP图，但不是128X64，用同样方法把图用画图软件打开，放大，加上网格，再进行编辑



编辑成自己想要的，



7.保存，退出画图。

8.双击打开取字模软件软件，点击“打开图像图标”按钮



9.点击‘参数设置’->其他选项，设置如下,

10.取模方式用C51格式，把点阵生成区的代码复制到程序中即可。

如果是彩图，先用Any to Icon软件转化成2色黑白图，重复以上步骤即可。

C语言代码：

#include<AT89X52.h>
#include<intrins.h>

#define uint unsigned int
#define uchar unsigned char
#define lcddataP0//宏定义lcddata为P0口数据

sbitrs=P2^0;//定义数据，命令端
sbitrw=P2^1;//定义读写端
sbite=P2^2;//定义使能端
sbit busy=P0^7;

uchar code tab[]=
