12864汉字显示和图片显示
吴鉴鹰单片机项目项目实战精讲之12864系列基于单片机驱动12864的滚动文字以及漫画图片的显示
吴鉴鹰单片机项目项目实战精讲之12864系列基于单片机驱动12864的滚动文字以及漫画图片的显示备注：相关原理图百度文库可以找到陪伴我长大的小伙伴多啦a梦首先吴鉴鹰让大家来欣赏几张漫画图片，重温一下童年的的美好时光。
这是一只可爱的老虎，可能也就画的比较可爱而已。
这是少儿的偶像喜羊羊鹰哥当时就产生了一个想法，作为一个学电子的专业的学生，能不能用液晶屏将这些图片显示出来呢？于是尝试着用12864显示着，事实证明效果还是可以的。
所以要相信电子行业很多东西，只有你想不到，没有做不到的，要敢想敢做。
下面鹰哥再带大家欣赏一下12864显示的效果：多啦A梦可爱的小老虎小狗显示喜羊羊小猫又像小老虎下面是相应的美女显示程序，只要你愿意做你也可以显示你的女神哦！程序介绍：1/******************************************************2*程序：LCD12664液晶显示原理3*4**这一讲的主要内容:LCD12664液晶显示原理5**功能描述:对滚动汉字和漫画图片的LCD12864的显示6**输入:7**液晶：Proteus元件库—AMPIRE128X64(无字库)8**内容：显示滚动汉字和漫画图片9**输出:10**11**全局变量:12**调用模块:13**14**作者:吴鉴鹰15**日期:14.03.121617备注：有什么错误的地方，欢迎各大烧友指正1819O(∩_∩)O~20*******************************************************/2122#include<AT89X52.h>23#include<intrins.h>24#include<math.h>25//#include"source.h"26#define

12864液晶图像显示图文教程——最全版
由图可以看到水平坐标一个单位是两字节（即 16 位 D15～D0），X 地址会自动加 1，是直接加一个单位 （即两字节 16 位），比如 0001（也即 0X80+000X80+01），从第一行第一列跳到第一行第二列。 代码： void display_image(uchar *p) { uchar i,j; write_cmd(0x34);//扩充指令集动作 write_cmd(0x34);//关绘图显示功能 /*上半屏显示设置*/ for(i=0;i<32;i++)//上半屏 { write_cmd(0x80+i);//垂直地址 write_cmd(0x80); //水平地址 for(j=0;j<16;j++) { write_data(*p);//连续写入 16 个字节 p++; } } /*下半屏半屏显示设置*/ for(i=0;i<32;i++)//下半屏 { write_cmd(0x80+i);//垂直地址 write_cmd(0x88);//水平地址 for(j=0;j<16;j++)//连续写入 16 个字节 { write_data(*p); p++; } } write_cmd(0x36);//开绘图显示 write_cmd(0x30);//回到基本指令集 } 源程序： #include <reg52.h> #include "12864.h" X 坐标（水平）方向以 2 字节 Byte 为单位，Y 坐标（垂直） 方向以 1 位 Bit 为单位，先连续写入垂直与水平坐标，再写入 两字节数据到 GDRAM。 这里是这样进行的：i=0 时，j=0,1 时，写入两字节到垂直 （0X80+00）水平（0X80+00）这格（D15～D0）里；然后 X 坐标地址自增 1， 地址变为垂直 （0X80+00） ， 水平 （0X80+01） 这格，在 j=2，3 时写入两字节，………一直到垂直（0X80+00） 水平（0X80+07）这格，在 j=14，15 时写入两字节，此时循环 for(j=0;j<16;j++)结束跳出，刚好第一行 128 位写完数据；然后 i++,开始写第二行……
带字库LCD12864自定义图形、汉字显示
带字库的LCD12864自定义图片、汉字显示
一、将图片修改成128*64像素
1、打开win7自带的画图软件，载入图片（图片不满足128*64）
2、点击重新调整大小（或者图片处右击鼠标），如下设置，保持纵横比不勾选。
3、图片另存为，选择单色位图。
二、LCD12864用ZIMO21软件取模（BMP图片）
1、基本设置里面设置LCD的大小（如果图片像素就是128*64就不需要设置，直接打开）
2、打开BMP图片（黑白）
3、发现图片偏小，不足128*64，此时生成的数据就缺少128*64个点，显示会照成错误，需要修改一下图片大小。
改成128*64
3、直接调入128*64图片
4、设置参数，如下
5、取模选择C51格式
6、显示效果
三、PCtoLCD2002图片取模设置
四、PCtoLCD2002汉字取模设置（根据程序而定）
1、汉字取模参数设置
2、显示效果如下。

引用12864液晶原理分析3他山之石2010-07-21 20:52:05 阅读7 评论0 字号：大中小小峰的12864液晶原理分析3一、ST7920控制IC的LCD12864实现反白显示从使用手册上可知，扩展指令里的0x03+行号即可实现反白对应行。
但是ST7920 控制器的128×64 点阵液晶其实原理上等同256×32 点阵，第三行对应的DDRAM 地址紧接第一行；第四行对应的DDRAM 地址紧接第二行。
所以128×64 点阵的液晶执行反白功能时实用意义不大，因为用户对第一行执行反白显示操作时，第三行必然也反白显示；第二行反白，第四行也必然反白。
其实还是有办法做到单行反白的，解决方法就是混用图形显示和字符显示。
其理论支持在于：在ST7920中，字符显示的DDRAM和图形的GDRAM是相互独立的，而最后显示到液晶上的结果，是两个RAM中数据的异或。
具体来说：假如某个点上，绘图RAM的没有绘图（数据为0），而字符RAM上有点阵（数据为1），那么异或的结果就是1，也就是说正常显示字符；当字符上RAM没有点阵的时候，异或的结果是0，自然也就不显示了。
假如该点上绘图RAM绘图了（数据为1），当字符RAM上有点阵（数据为1时），异或的结果为0，效果就是反白显示；如果字符RAM没有点阵（数据为0时），异或结果为1，效果就是显示绘图的背景。
所以，如果要在某个地方反白显示，那么就在该点绘图并且写字，如果要取消反白，就重新用全0擦掉那个地方的绘图！这样一来可以实现任何地方、任意大小的反白显示，反而比原指令中的单行反白的功能更好更强大。
二、对于整屏既有图象又有文本，则可以用两种方式实现：1、首先文本DDRAM写入要写的字符，其余全部空格（即0X00），然后再在没有字符的地方（即非点亮的晶格中，0X00）绘入图象。
DDRAM与GDRAM异或后就可以整屏实现图象与文本。

J12864中文液晶使用说明
J12864中文液晶使用说明
一、硬件连接
二、软件设置
1.安装液晶库文件
将液晶库文件拷贝到单片机的编程环境中，以便在程序中调用相关函数。
2.初始化液晶
在程序的初始化函数中，调用液晶库提供的初始化函数，以初始化液晶参数和相关引脚。
三、显示中文字符
然后，在程序中调用液晶库中的函数，以显示中文字符。
通常的调用方式为：
lcd_draw_chinese(x, y, "你好");
函数参数说明：
-x：起始横坐标
-y：起始纵坐标
-"你好"：待显示的中文字符
四、显示英文字符和数字
显示英文字符和数字与显示中文字符类似，只是液晶库提供了额外的函数用于显示英文字符和数字。
调用方式如下：
显示英文字符：
lcd_draw_english(x, y, "Hello");
函数参数说明：
-x：起始横坐标
-y：起始纵坐标
- "Hello"：待显示的英文字符
显示数字：
lcd_draw_number(x, y, number);
函数参数说明：
-x：起始横坐标
-y：起始纵坐标
- number：待显示的数字
五、显示图形
六、注意事项
2.操纵液晶模块时应轻拿轻放，避免撞击或扭曲。
3.在使用中文液晶时，应注意控制芯片ST7920的工作电压和时序要求。
4.如果需要显示中文字符，首先要将中文字库文件转换成液晶可识别的格式。
5.当在程序中使用液晶库进行液晶控制时，需注意调用顺序和参数的正确性。
总结：。
