void Lcd12864Clear(uint8 selet)
{
uint8 i,j;
Lcd12864SeletScreen(selet); //选择屏，分左屏和又屏，这个函数在程序中有
for(i = 0;i < 8 ;i++)
二．写入地址
void Lcd12864Point(uint8 page,uint8 x,uint8 y)
{
Lcd12864Write(CMD,0xb8 + page);
//确定页
Lcd12864Write(CMD,0xC0 + x);
//设定起始行
Lcd12864Write(CMD,0x40 + y);

现在开始讲解如何使用，看这篇讲解前，请先到网盘去下载本教 程的仿真图和程序，结合起来更容易明白。
上图是仿真的结果。 在仿真软件中找出的 12864 液晶是没有字库的，对于仿真软件中 液晶的控制和平常的有点不同。一块液晶是由两块 64×64 的液晶显 示模块组合而成。下面是各管脚的介绍。
//有 8 页，循环 8 次
{
Lcd12864Point(i,0,0); //这个就是上面讲到的函数，确定位置
for(j = 0 ;j < 64;j++) //每一块液晶显示模块有 64 列
{
Lcd12864Write(DAT,0x00); //写入 0x00 来清屏
}
}
}
具体的使用如下：初始化函数中调用了清全屏 Lcd12864Clear(3); //清全屏

4.上面设置好之后我们就可以在文字输入区输入汉字了，以“Ctrl”+“Enter”结束：
5.然后点击“C51格式”，在点阵生成区就会出现相应的模如下，我们可以把每个汉字对应的模存放在相应的数组中：
上面为取模软件的使用方法，下面开始正式教给读者单片机驱动lcd12864液晶显示屏的方法，在这之前，需要对无字库lcd12864液晶显示屏有个基础的了解，相关引脚如下：
void LCDDelay (char t)
{
char i, j;
for (i = 0; i < t; i ++ )
for (j = 0; j < 10 ;j ++ );
}
void CheckState ( )
{
char dat;
LCDRs = 0;
LCDRw = 1;
do
{
dat = 0x00;
LCDEn = 1;
LCDEn = 0;
}
void LCDInit ( )
{
LCDDelay (100);
LCDCs1 = 1;
LCDCs2 = 1;
LCDDelay (100);
write_com (LCDDispOff);
write_com (PageAdd+0);
write_com (StartLine+0);
write_com (LCDColAdd+0);

LCD12864（不带字库）
LCD12864（不带字库）LCD12864（不带字库）其实看了本版的1602教程以后很容易就可以掌握12864了。
刚才看到有网友要12864教程，俺就把博客里以前练习的一个程序弄过来，算作参考吧。
不足之处请见谅。
这个程序浪费了我很多时间，因为我一直没有找到datasheet，12864的型号实在太多了。
为了这个程序，我在网上找了很多相关的例程，但大多都是C语言写的，可惜俺没学过C，用起来不顺手，遂将其转成汇编，但是转后，程序运行不正常，郁闷啊。
好不容易找个汇编的吧，又写得很乱，没有头绪，没有datasheet，看起来很费劲，最后终于找到一个相关的datasheet，这才完成这个程序。
总结一下：与其费力分析别人的程序，不如看datasheet自己写。
下面总结一下datasheet。
→↑←ONE→且看datasheet：12864点阵型LCD简介12864是一种图形点阵液晶显示器,它主要由行驱动器/列驱动器及128×64全点阵液晶显示器组成。
可完成图形显示，也可以显示8×4个(16×16点阵)汉字。
在使用12864LCD前先必须了解以下功能器件才能进行编程。
12864内部功能器件及相关功能如下：1. 指令寄存器(IR)IR是用于寄存指令码，与数据寄存器数据相对应。
当D/I=0时，在E信号下降沿的作用下，指令码写入IR。
2．数据寄存器(DR)DR是用于寄存数据的，与指令寄存器寄存指令相对应。
当D/I=1时，在下降沿作用下，图形显示数据写入DR，或在E信号高电平作用下由DR读到DB7∽DB0数据总线。
DR和DDRAM之间的数据传输是模块内部自动执行的。
3．忙标志：BFBF标志提供内部工作情况。
BF=1表示模块在内部操作，此时模块不接受外部指令和数据。
BF=0时，模块为准备状态，随时可接受外部指令和数据。
利用STATUS READ指令，可以将BF读到DB7总线，从检验模块之工作状态。

二、显示图片
显示图片和显示汉字的原理是一样的， 只不过是大小的问题！ 现在我们就以一张 128*64 分辨率的图片进行取模。 取模图片：
现在我们主要看一下显isplay_BMP(uchar a[][64])//显示图形的左边部分 { uchar i,j; for(j=0;j<8;j++) { SelectScreen(1); Set_page(j); Set_column(0); for(i=0;i<64;i++) //显示左屏 { write_LCD_data(a[2*j][i]);//每隔一行取一次数组中的数据 } SelectScreen(2); Set_page(j); Set_column(0); for(i=0;i<64;i++) //显示右屏 { write_LCD_data(a[2*j+1][i]);//每隔一行取一次数组中的数据 } } } 取出图片的数据是二维数组形式！注意，液晶是先显示左半屏，再显示右半屏， 但 是取数组中的元素是逐个往下取出的， 所以是对于一个半屏而言， 每隔一行取数组中的元素， 而隔去的那一行是另一个半屏要取的数据！这一点一定要注意。 还有一点要补充的就是，这个取模软件只能识别 BMP 和 ICO 格式的单色图片，如果我 们选择的图片不是 128*64 大小的话， 可以通过软件将其改成 128*64 大小的， 如果我们直接 用软件取模的话，显示的会是乱码，解决办法是我们可以通过 windows 自带的画图工具， 什么也不做修改，将大小设置好的图片另存为 BMP 单色文件就行了，然后再用取模软件取 模就 OK 了，=^_^ = ！算了，给大家截个图

还要注意的是：带中文字库和不带中文字库的程序不一样，
不可混用。
