Arduino教程（提高篇）——驱动12864LCD模块

mini12864图：

mini12864可配合取模软件及各种单片机可完成中文汉字、英文字符和图形显示，更适合Arduino做显示相关的互动作品，该mini液晶屏成本相对较低，适用于各类仪器，小型设备的显示领域。

由于LCD驱动IC众多，这里我们仅以OPENJUMPER的mini12864LCD为例教学，其他的LCD，你只需找到不同的库来驱动即可。

下面按步骤来驱动mini12864显示图片：

第一步：下载取模软件

字模提取V2.2.zip

第二步：处理图片，把你想要mini12864显示的图片，用软件处理为128*64的.bmp图

如图：

第三步：使用取模软件

1、打开取模软件，新建图像，选择宽度128，高度64

2、打开你的图片，将做好的分辨率为128*64的.bmp图导入

3、反向取模，由于此处用的液晶点阵为反向显示，这里的取模须反向取模。(取消这一步，使用程序库里函数也可以达到此效果反向显示)

4、生成数组，并复制下面的数组<br />

第四步：下载库文件

Lcd12864.zip

，安装在arduino安装文件的libraries下面，打开IDE，敲入下面示例代码。

第五步：复制刚才生成的数组，取代 bmp3[1024]里面的所有数组，编译并下载到您的arduino里。[C] 纯文本查看 复制代码

#include "Lcd12864.h"
#include "SPI.h"

unsigned char const bmp3[1024]={

第六步：mini12864与arduino之间的接线。 CS—— 8 //片选低有效

RST—— 9 //给芯片复位，低有效，如果不需软件给芯片复位，可不连接 A0——10 //数据和命令选择，L 命令 H数据CLK——13 //时钟MOSI——11 //数据GND——GND //电源接线VCC——5VLED——背光选择 //低有效
