原创 AVR(Mega8)的study:12、点亮LCD3510液晶

 2008-3-15 11:03  2715 6 6 分类: MCU/ 嵌入式

现在手里的液晶基本都没了，12864、12232什么的都不见影了，还有一块诺基亚手机3510上拆下来的液晶，以前点过，现在用Mega8再点点。由于Mega8的资源有限，不能一次做多个测试，只能一个个的做了。要3510资料的可以上BAIDU搜搜，有很多。

测试效果：

//3510.c

#include <iom8v.h>
#include "mytype.h"
#include "math.h"
#include "lcd3510.h"
//#include "ascii.h"
