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 (512.81 KB) (下载次数: 3866, 2012-8-29 10:35 上传) 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 第四步：下载库文件 Lcd12864.zip (2.65 KB) (下载次数: 4430, 2012-8-29 14:44 上传) ，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。 [mw_shl_code=c,true]#include "Lcd12864.h" #include "SPI.h" unsigned char const bmp3[1024]={ 0x00,0x00,0x00,0x00,0x00,0x00,0xC0,0xC0,0xF0,0x30,0x30,0x30,0x30,0x30,0x30,0x30, 0xF0,0xC0,0xC0,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

看下这个屏啥驱动，下载ardinuoIDE。选择你的开发板，下载开发板驱动库，安装这个屏的驱动库，然后学习例程，最后自己调用驱动库函数驱动这块屏，做你想做的事。
