本文不讨论显示驱动，只讨论怎样通过软件对图片进行取模然后让12864显示。

1、将需要显示的图片进行处理

首先12864只能显示黑白图像而且不能显示灰度，因此可以确定图片的要求：

图像大小：128像素*64像素

图像格式：bmp

图像位数：1

处理方法如下：

先将要显示的图像进行裁剪，按照2:1的比例

更改图像大小为128像素*64像素

保存图像为bmp格式颜色深度为1或者就是黑白模式

以上操作可以使用Photoshop来完成，通过以上操作可以得到要显示的图片。

2、导入图像进行取模

到网上找一个PCtoLCD2002的软件，点击打开导入刚刚生成的图像

点击选项按照图进行设置

上面的设置是我试验得到的，阴码和阳码显示的颜色是相反的，取模走向的区别是显示的是镜像关系，根据程序中的格式选择相应的前后缀生成字模即可。

如河海大学的书法字模：const unsigned char hohai[] = { 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,
