单片机的动手实践篇--51单片机玩转12864
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
![](../img/eep/emb/emb-745692i40h3mgsfg.jpg)
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, */
