3、LCD原理简图
4、LCD主要功能介绍
1）显示数据RAM（DDRAM）
DDRAM64X8X8 bits）是存储图形显示数据的。此RA啲每一位 数据对应显示面板上一个点的显示（数据为H与不显示（数据为L）。DDRA的地址与显示位置关系对照图（见附录一）
8）丫地址计数器
丫地址计数器是一个6位循环加一计数器。它管理某一页面上的64个单元。丫地址计数器可以由MP以指令形式设置，它和页地址指针结 合唯一选通显示存储器的一个单元，丫地址计数器具有自动加一功能。
在显示存储器读/写操作后丫地址计数将自动加一。当计数器加至3FH后 循环归零再继续加一。
9）Z地址计数器

12864之Protues仿真
装上12864具体的电路还是两个电阻。
一个背光限流电阻。
一个液晶驱动电压调节电阻。
背光电阻还是任何时候在19、20脚与电源之间串上个100欧电位器接上电源。
调节电位器到合适亮度。
具体值最好是到调试完程序能够正常显示后再将阻值确定换成固定电阻。
液晶驱动电压的调整在数据线、电源线接好的前提下是在Vee(-15v)和地之间接一个电位器。
中间接V0，通过调节电位器来调节V0上的电压。
当V0上为-15V时为全暗(液晶显示为全黑)。
当V0为0V时为全亮。
调节电位器使屏幕从全暗刚好变到亮时，便可进行程序的调试。
待屏幕显示正常后，进行对比度的细调，然后测量这两边的阻值在地和V0之间、V0和Vee之间换成两个固定电阻焊上就好了。
注意在V0的电压是在一个很小的范围有效。
我的就是在-2.2——-2.5这个范围。
仔细调节V0和地之间的电阻使V0上的电压在2.3V。
更换为固定电阻后的装配图：下面说说具体的驱动：先来了解一下LCD12864的内部控制结构：见图可以看出12864屏是分为左、右两块控制的。
所有对屏幕的操作要受片选CS1、CS2来控制。
我们再来看一看对屏幕操作数据与屏幕点阵的排布关系：见下图。
从上图可以看出数据按字节在屏幕上是竖向排列的。
上方为低位，下方为高位。
因此在横向上(也就是Y)就一共是128列数据。
分为CS1和CS2两个64列来写入。
在竖方向上(也就是X)一字节数据显示8个点，竖向64个点分为8个字节，称做8页(X=0-7)。
了解这些后我们就知道要满屏显示一张图就要从y=0…127、X=0…7一共写128×8=1024个字节的数据。
同样在AT89S51中存一张图就要1024个字节的空间。
好!下面我们来了解对LCD12864进行操作的一些指令。
下面对上图的指作解释：1.显示开关控制(DISPLAY ON/OFF)D=1:开显示(DISPLAY ON) 意即显示器可以进行各种显示操作D=0:关显示(DISPLAY OFF) 意即不能对显示器进行各种显示操作2.设置显示起始行(DISPLAY START LINE)前面在Z地址计数器一节已经描述了显示起始行是由Z地址计数器控制的。

Protues中单片机驱动12864仿真
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 LCDWriteChineseBlack (char leftright, char page, char column, char chinese[]);//12864指定页指定列显示一个汉字，以黑色背景白色文本显示
void LCDWriteNum (char leftright, char page, char column, char num[]);//12864指定屏指定页指定列显示一个数字
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;
参数leftright用来使能左半屏或者右半屏（‘L’或者’R’），
参数page用来选择在哪一页显示（0~7），
参数column用来选择在哪一列显示（0~64），
参数num[]即为待显示汉字的模。
使用Proteus模拟操作HDG12864F-1液晶屏
使⽤Proteus模拟操作HDG12864F-1液晶屏 在Proteus中模拟了89C52操作HDG12864F-1液晶屏，原理图如下：⼀、HDG12864F-1官⽹信息 该液晶屏是Hantronix的产品，官⽹上搜索出这个型号是系列型号中的⼀种，各种型号间的区别主要是尺⼨不同、有⽆背光、背光颜⾊等等。
下⾯是官⽹中⼏个⼿册的链接：，该液晶屏的控制器使⽤的是爱普⽣SED1565系列官⽹照⽚⼆、基本操作函数 根据⼏个⼿册提供的信息，“写命令”和“写数据”函数如下：1 sbit cs = P1^7;//-cs，⽚选，低电平有效2 sbit rst = P1^6;//-rst，复位，低电平有效3 sbit a0 = P1^5;//写命令、写数据控制位。
1=Display data; 0=Control data;4 sbit wr = P1^4;//-Write serial data，写串⼝数据，低电平有效5 sbit rd = P1^3;//-Read serial data，读串⼝数据，低电平有效6 sbit scl = P1^2;//Shift clock input，时钟输⼊7 sbit si = P1^1;//Serial data input，串⼝数据输⼊8//⼿册中说了，各种操作都是ns级，不⽤各种等待命令，下⾯操作也没有写⼊等待功能9//写命令10void wrt_cmd(unsigned char command)11 {12 unsigned char i = 8;13 cs = 0;14 a0 = 0;//0=Control data，命令置015 wr = 0;16 rd = 1;17while(i--){18 scl = 0;19 si = (bit) (command & 0x80);//先写⾼位20 scl = 1;21 command <<= 1;22 }23 scl = 0;24 }25//写数据26void wrt_dt(unsigned char data_)27 {28 unsigned char i = 8;29 cs = 0;30 wr = 0;31 a0 = 1;//1=Display data，写数据置132 rd = 1;33while(i--){34 scl = 0;35 si = (bit) (data_ & 0x80);36 scl = 1;37 data_ <<= 1;38 }39 scl = 0;40 }三、显存和屏幕的对应关系 ⼿册中有描述，不太好理解，⽹上也查了不少，还是⽤⾃⼰的⽅法好理解⼀些。
串行方式使用12864的proteus仿真实例
程序如下：
/*取模方式：行列式逆向阴码*/
/*参数A0=0时表示发命令A0=1时表示发送示数据*/
#include <reg52.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
sbit LCD_SI=P3^0;//clock input同步时钟输入端
LCD_write(0x04|(0x0f&column_f),0); //设定列地址低4位为0
for(j=0;j<column_sum;j++)
{
LCD_write(BMP[d_where],1);
d_where++;
}
}
}
//------------------------------------------------------------------------------
sbit LCD_SCL=P3^1;//data input/output串行数据输入、输出端
sbit LCD_A0=P3^2;//选择命令还是数据
sbit LCD_RST=P3^3;//复位
sbit LCD_CS=P3^4;//片选
uchar code BMP[]=
{0xFB,0xDB,0xBB,0x7B,0x9B,0x63,0xBF,0xCF,0xF0,0x37,0xF7,0xF7,0xD7,0xE7,0xFF,0xFF,
LCD写函数
void LCD_write(数据或者命令，A0选择)

基于proteus的不带字库的12864的仿真程序（带仿真图）作者：心如止水（武汉工程大学）/****************************************************** ******本程序为不带字库的12864汉字及英文字符的显示程序，可以说此程序是所有12864显示程序中最简单最易懂的显示程序。
之所以写这个程序，是因为我看很多学单片机的人（特别是初学者）对12864有一种恐惧感，觉得它很难，看完这个程序，相信你能明白它的显示原理。
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。
