[导读]12864液晶的驱动和1602的类似，只不过是多了几个扩展的功能，不如画图功能

12864液晶的驱动和1602的类似，只不过是多了几个扩展的功能，不如画图功能：

这里讲一下：不要简单的认为12864是y轴64，x为128，那是点阵的分布，不是读写的分布，如正图表示，y轴的32行，从0到31，x轴的16 从0到15,0到7为上半个屏幕，8到15在下半个屏幕，所以绘图的时候，有两个部分要进行书写

在12864上载入任意一幅图：

示例代码：

#include

#define uint unsigned int

#define uchar unsigned char

sbit lcdrs = P2^4;//数据还是指令的选择端口

sbit lcdwr = P2^5;//读写操作端口

sbit lcden = P2^6;//使能端延时端口

sbit PSB = P2^1;//串行数据还是并行数据的选择段

//图片的编码，这幅图片的编码是一个哆啦a梦

unsigned char code pic1[] = { /* 0X10,0X01,0X00,0X80,0X00,0X40, */

0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,0X00,

以后载入图片只需要将图片用取模的软件，注意图片的大小必须是128x64的尺寸，否则会出现乱码，这是个比较容易犯的错误，希望大家注意
