51单片机YM12864汉字图形点阵液晶显示模块

51单片机YM12864汉字图形点阵液晶显示模块

51单片机YM12864汉字图形点阵液晶显示模块&#173;本文以AT89C51单片机控制使用比较普遍的YM12864液晶显示器为基础，介绍了一种采用分页原理实现多级中文菜单操作的方法。

给出了YM12864主要技术参数、显示特性和核心的程序。

设计的中文菜单具有一定的通用性，只需更改其中的菜单项即可将此设计应用到家电、仪器仪表等设备上，为操作者提供友好方便的中文操作界面。

51单片机YM12864汉字图形点阵液晶显示模块-_典型应用电路图。

目前小型的显示器主要有LCD和LED,LED显示器只能显示数字和有限个英文字符，不能显示汉字，显示内容不直观，操作人员只能根据约定格式了解显示内容。

而LCD则可显示各种汉字和图形，尤其能实现中文菜单显示，为操作者提供方便友好的操作界面，并且功耗低，因此LCD得到广泛应用。

而现在市面上带中文字库的LCD比比皆是，价格适中，且大部分具有与MUC统一的标准接口，为使用LCD实现中文菜单操作提供了很大的方便。

相信更多的电子产品在提升性能的同时，设计更加人性化的中文菜单交互界面，将会使产品具有更广阔的前景。

二、YM12864液晶显示模块简介YM12864汉字图形点阵液晶显示模块，可显示汉字及图形，内置8192个中文汉字（16X16点阵）、128个字符（8X16点阵）及64X256点阵显示RAM（GDRAM）。

主要技术参数和显示特性：电源：VDD 3.3V~+5V（内置升压电路，无需负压）显示内容：128列×64行与MCU接口：8位或4位并行/3位串行多种软件功能：光标显示、画面移位、自定义字符、睡眠模式等。

其引脚功能为通用20脚LCD接口，用户指令集也为通用128*64LCD用户指令集，相关资料很容易获取。

因其内置中文字库，省去了自己造字库的工作量，而只需写入相应的汉字和字符内码即可显示所需要的汉字和字符，这在许多程序开发软件中很容易实现，如：WAVE、KEIL等。

51单片机综合学习系统之12864点阵型液晶显示篇

51单片机综合学习系统之12864点阵型液晶显示篇

51单片机综合学习系统之 12864点阵型液晶显示篇大家好，通过以前的学习，我们已经对51单片机综合学习系统的使用方法及学习方式有所了解与熟悉，学会了1602字符型液晶显示的基本知识，体会到了综合学习系统的易用性与易学性，这一期我们将一起学习12864点阵型液晶显示屏的基本原理与使用方法。

点阵LCD的显示原理在数字电路中，所有的数据都是以0和1保存的，对LCD控制器进行不同的数据操作，可以得到不同的结果。

对于显示英文操作，因为英文字母种类很少，只需要8位<一字节）即可。

而对于中文，常用却有6000以上，于是我们的DOS前辈想了一个办法，就是将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。

而剩下的低128位则留给英文字符使用，即英文的内码。

那么，得到了汉字的内码后，还仅是一组数字，那又如何在屏幕上去显示呢？这就涉及到文字的字模，字模虽然也是一组数字，但它的意义却与数字的意义有了根本的变化，它是用数字的各位信息来记载英文或汉字的形状，如英文的'A'在字模的记载方式如图1所示：图1 “A”字模图而中文的“你”在字模中的记载却如图2所示：图2 “你”字模图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。

12864图形液晶显示模块与51系列单片机接口技术

12864图形液晶显示模块与51系列单片机接口技术

单片机与可编程器件液晶显示模块以其微功耗、体积小、显示内容丰富、模块化、接口电路简单等诸多优点得到广泛应用。

液晶显示模块分字符型和点阵型两种，前者只能显示常用的字符，点阵型液晶显示模块除显示字符外还能显示各种图形和汉字。

目前，尽管液晶显示模块种类繁多，但其结构及控制方法是一样的，本文以常用的１２８×６４液晶显示模块为例介绍液晶显示模块的工作原理及其与５１系列单片机的接口技术。

１２８６４图形液晶显示模块１２８６４液晶显示模块表示横向有１２８点，纵向有６４点，可显示１６×１６中文字４行，每行８个字，外形和引脚排列如图１所示。

１．　引脚功能 引脚功能如表１所示。

２．　显示ＤＤＲＡＭ与Ｘ地址、Ｙ地址排列方式 ＤＤＲＡＭ是模块自带的存储单元，用来存放图形信息或数据，ＤＤＲＡＭ存储单元与液晶显示屏之间存在一一对应关系，数据为１表示显示选择，对应屏幕亮；数据为０表示显示非选择，对应屏幕不亮。

ＤＤＲＡＭ与Ｘ、Ｙ地址和显示位置的关系如表２所示。

３．１２８６４液晶显示模块指令１２８６４液晶显示模块基本操作指令如表３所示。

（１）读取状态字 当Ｒ／Ｗ＝１，Ｄ／Ｉ＝０时，在Ｅ信号为高的作用下，状态字分别输出到数据总线上。

状态字是了解模块当前工作状态的唯一的信息渠道，在每次对模块操作之前，都要读出状态字判断ＢＵＳＹ是否为“０”。

若不为“０”，则计算机需要等待，直至ＢＵＳＹ　＝０为止。

（２）显示开关设置 Ｄ＝１开显示，Ｄ＝０关显示。

（３）显示起始行设置 指令表中ＤＢ５～ＤＢ０为显示起始行的地址，取值在０～３ＦＨ（１～６４行）范围内，它规定了显示屏上最顶一行所对应的显示存储器的行地址。

（４　）　页面地址设置 页面地址是ＤＤＲＡＭ的行地址。

８行为一页，ＤＤＲＡＭ共６４行即８页，ＤＢ２￣ＤＢ０表示０￣７页。

（５）列地址设置 列地址是ＤＤＲＡＭ的列地址。

共６４列，１２８６４图形液晶显示模块与５１系列单片机接口技术・湖南邵阳学院电气信息工程学院 江世明・摘要 文章以１２８×６４液晶显示模块为例，系统地介绍了１２８６４图形液晶显示模块的结构特征、指令系统、工作时序及与５１系列单片机接口技术、编程方法。

51单片机带字库12864液晶动态汉字显示C语言源程序

51单片机带字库12864液晶动态汉字显示C语言源程序

51单片机带字库12864液晶动态汉字显示C语言源程序2009-10-17 19:36实验芯片为：AT89S52，带字库液晶屏：12864，实现的目的：动态一个汉字一个汉字显示。

其实和显示汉字的程序一样，只是稍做一下修改即可。

C语言源程序如下：#include <stdio.h>#include <math.h>#include <reg52.h>#include <string.h>sbit RS=P2^4;sbit WRD=P2^5;sbit E=P2^6;sbit PSB=P2^1;sbit RES=P2^3;void TransferData(char data1,bit DI);void delayms(unsigned int n);void delay(unsigned int m);void lcd_mesg003(unsigned char code *addr1);unsigned char code IC_DAT[]={"我是一个中国人啊"};void initinal(void){delay(40);PSB=1; //并口工作模式delay(1);RES=0; //复位delay(1);RES=1; //复位置高delay(10);TransferData(0x30,0);delay(100);TransferData(0x30,0);delay(37);TransferData(0x08,0);delay(100);TransferData(0x10,0);delay(100);TransferData(0x0C,0);delay(100);TransferData(0x01,0);delay(10);TransferData(0x06,0);delay(100);}void main(void){while(1){initinal();//调用LCD字库初始化程序delay(100);lcd_mesg003(IC_DAT);}}void lcd_mesg003(unsigned char code *addr1){unsigned char i;//第一行TransferData(0x80,0);delay(100);for(i=0;i<16;i++){TransferData(*addr1,1);addr1++;delayms(50);}}void TransferData(char data1,bit DI) //传送数据或是命令，当DI=0时，传送命令，当DI=1时，传送数据{WRD=0;RS=DI;delay(1);P0=data1;E=1;delay(1);E=0;}void delayms(unsigned int n){unsigned int i,j;for(i=0;i<n;i++)for(j=0;j<2000;j++);}void delay(unsigned int m){unsigned int i,j;for(i=0;i<m;i++)for(j=0;j<10;j++);}原理就是在显示每个汉字的时候加了一个延时程序，当然可以用定时器来实现，这样的话，不占用CPU处理时间。

51单片机LCD12864绘图

51单片机LCD12864绘图

LCD12864绘图方法如下：一、绘图方法：1、使用扩展指令集并关闭绘图显示2、输入y轴坐标3、输入x轴坐标4、写入数据D15-D85、写入数据D7-D06、开绘图显示7、返回普通指令对应程序如下：LCD_write_comm(0x34);//使用扩充指令集LCD_delay();LCD_write_comm(0x80+y);//y坐标起始地址LCD_delay();LCD_write_comm(0x80+x);//x坐标起始地址LCD_delay();LCD_write_date(0x55);//写入数据D15-D8LCD_delay();LCD_write_date(0x55);//写入数据D7-D0LCD_delay();LCD_write_comm(0x36);//显示RAMLCD_delay();LCD_write_comm(0x30);//退出扩展指令集LCD_delay();程序执行效果则是第一行的第1-16个像素点会描出0x5555的二进制像素点，则后面的整个屏幕则是花屏，如果只想看到这0x5555,这几个像素点，则必须要给LCD的RAM重新赋值，也可以说是清屏，程序如下：void LCD12864_RAM_Cls(){u8 x,y;//xy坐标LCD_write_comm(0x34);//使用扩充指令集LCD_delay();for(y=0;y<32;y++){LCD_write_comm(0x80+y);//y坐标起始地址LCD_delay();LCD_write_comm(0x80);//x坐标起始地址LCD_delay();for(x=0;x<16;x++){LCD_write_date(0x00);LCD_delay();LCD_write_date(0x00);LCD_delay();}}LCD_write_comm(0x36);//显示RAMLCD_delay();LCD_write_comm(0x30);//退出扩展指令集LCD_delay();}二、坐标与显示X轴坐标设定初始值后会自动加1，取值范围0-15Y轴需要人为加1，取值范围为0-31整个屏幕分为上下屏，上屏对应坐标为x(0-7)y(0-31),下屏对应坐标为x(8-15)y(0-31)三、LCD12864图片显示代码1、Main.c#include"common.h"#include"delay.h"#include"12864.h"unsigned

可使用4位/8位并行、2线或3线串行多种接口方式，拥有多种字库的点阵图形液晶显示模块；接口方式灵活，操作指令简单、方便，可构成全中文人机交互图形界面。

可以显示汉字，也可完成图形显示；电压、功耗较低；硬件电路结构与显示程序都要简洁，同时价格也略低于相同点阵的图形液晶模块。

关键词：51单片机12864LCD 显示屏动态静态图像引言带中文字库的TS128X64（图1）具有4位/8位并行、2线或3线串行多种接口方式，引脚功能见图2。

其内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64，内置8192个16*16点汉字，和128个16*8点ASCII字符集。

图1 TS12864液晶实物图该模块接口方式灵活和操作指令简单、方便，可构成全中文人机交互图形界面。

可以显示8×4行16×16点阵的汉字。

也可完成图形显示，有低电压低功耗的特点。

由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构还是显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。

本设计讲采用STC89C52对TS128X64进行驱动，设计并制作LCD驱动电路，使其可通过按键切换LCD的显示内容，并且实现对数字，汉字，英文以及图片的显示，滚屏，以及动画功能。

1.硬件设备STC89C52是STC公司生产的一种低功耗、高性能CMOS8位微控制器，具有8K 在系统可编程Flash存储器。

STC89C52使用经典的MCS-51内核，但做了很多的改进使得芯片具有传统51单片机不具备的功能。

在单芯片上，拥有灵巧的8 位CPU 和在系统可编程Flash，使得STC89C52为众多嵌入式控制应用系统提供高灵活、超有效的解决方案。

具有以下标准功能：8k字节Flash，512字节RAM，32 位I/O 口线，看门狗定时器，内置4KB EEPROM，MAX810复位电路，3个16 位定时器/计数器，4个外部中断，一个7向量4级中断结构（兼容传统51的5向量2级中断结构），全双工串行口。

对于前端加工工序来说，关键设备是高通量印刷
机、研磨机、装配机、清洗机。主要加工因素是良好的表
面清洁度、低颗粒污染率、良好的器件单元间隔和厚
度层控制。后端生产过程与传统ＬＣＤ生产相比不变。
结论
电子纸市场发展迅速。Ｎｅｍｏｐｔｉｃ作为市场的主 导和积极角色，已经和它的制造伙伴Ｓｅｉｋｏ Ｉｎｓｔｒｕｍｅｎｔｓ，Ｉｎｃ建立了一个ＢｉＮｅｍ液晶显示器模 块的批量生产基地。
