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。

可以显示8×4行16×16点阵的汉字. 也可完成图形显示.低电压低功耗是其又一显著特点。

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，不论硬件电路结构或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。

基本特性:●●低电源电压（VDD:+3.0--+5.5V）●●显示分辨率:128×64点●●内置汉字字库，提供8192个16×16点阵汉字(简繁体可选)●●内置 128个16×8点阵字符●●2MHZ时钟频率●●显示方式：STN、半透、正显●●驱动方式：1/32DUTY，1/5BIAS●●视角方向：6点●●背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10 ●●通讯方式：串行、并口可选●●内置DC-DC转换电路，无需外加负压●●无需片选信号，简化软件设计●●工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃二、方框图3、外形尺寸图三、模块接口说明*注释1：如在实际应用中仅使用串口通讯模式，可将PSB接固定低电平，也可以将模块上的J8和“GND”用焊锡短接。

在此指出，这一篇文章出至网络上zhaoshan413之手，感谢他的无私贡献，让大家轻松玩转带字库12864！~~[p=30, 2, left]之前说学完12864字库液晶后和大家交流一下心得，一直没有时间，今天整理一下发上来，希望对想学习的朋友能有点帮助…首先说明一点，本人也是初学者，自感水平不高，若有不足及不对之处，望情指正…以下以并行口传输为例，别的还不会，呵呵![/p][p=30, 2, left]先传一下ST7920的芯片说明书：[/p][p=30, 2, left]/bbs/redirect.php?tid=7676&goto=lastpo st#lastpost[/p][p=30, 2, left]ST7920(字库)12864.pdf(2010-12-01 10:46:58, Size: 1.65 MB, Downloads: 1689)[/p][p=30, 2, left]一、首先说一下关于驱动函数的书写，这些是液晶显示的基础一般包括四个函数：1、写命令函数；2、写数据函数；3、读状态函数；4、读数据函数；这四个函数并不是必须全部写的，具体要看你实现的功能，如果只是单纯的显示汉字和字符，写命令、写数据、读状态这三个函数就够了，如过你还需要进行一些绘图的操作，那读数据函数也必须书写。

另外关于读状态函数，其实也就是用于判忙操作，我看郭天祥的书里面是这样说的：原则上每次对控制器进行读写操作之前，都必须进行读写检测，由于单片机的操作速度慢于液晶控制器的反应速度，因此可不进行读写检测，或者只进行简短的延时即可。

因此，读状态函数也可以不写，只用简短的延时函数替换即可。

1、写操作的编写：首先看一下时序图[/p][p=30, 2, left]时序.JPG[/p][p=30, 2, left]由图可见操作很简单：1>RS=1(写数据操作)；或者RS=0(写命令操作)；2>RW=0；//指明为写操作3>E=1；4>DB=data；//data为你要写入的命令或数据值5>E=0；[/p][p=30, 2, left]以下是我的驱动函数，仅供参考：[/p][p=30, 2, left]CODE:/********************************液晶端口定义**************************/#define lcd_data P0 //数据口sbit RS = P2^4; //选择寄存器(并行) 0：指令寄存器1：数据寄存器;sbit RW = P2^5; //读写控制脚(并行) 0：写入 1：读出sbit E = P2^6; //读写数据启始脚(并行)sbit PSB = P2^1; //串并方式选择引脚，0为串行模式，1为8/4位数据口模式sbit RST = P2^3; //复位引脚//******************************************************* *//延时函数//******************************************************* *void delay(unsigned int k){unsigned int i;unsigned char j;for(i=0;i<k;i++){for(j=0;j<10;j++);}}//******************************************************* *//延时1ms函数//******************************************************* *void delay_ms(unsigned int k)//延时0.994us，晶振12M{unsigned int x,y;for(x=k;x>0;x--)for(y=121;y>0;y--);}//******************************************************* *//写命令函数//******************************************************* *void LcdWcom(unsigned char WCom){delay(1);RS=0; //指明操作对象为指令寄存器RW=0; //指明为写操作E=1;lcd_data=WCom; //将命令写入总线E=0;}//******************************************************* *//写数据函数//******************************************************* *void LcdWdata(unsigned char WData){delay(1);RS=1; //指明操作对象为数据寄存器RW=0; //指明为写操作E=1;lcd_data=WData; //将数据写入总线E=0;}[/p][p=30, 2, left]二、初始化操作[/p][p=30, 2, left]以8位并行操作为例，操作流程图如下：[/p][p=30, 2, left]初始化.JPG[/p][p=30, 2, left]初始化操作如下：[/p][p=30, 2, left]1>芯片上电；[/p][p=30, 2, left]2>延时40ms以上；[/p][p=30, 2, left]3>复位操作：RST出现一个上升沿（RST=1;RST=0;RST=1;）；[/p][p=30, 2, left]4>功能设定；[/p][p=30, 2, left]5>延时100us以上；[/p][p=30, 2, left]6>再次进行功能设定；[/p][p=30, 2, left]7>延时37us；[/p][p=30, 2, left]8>显示开关控制；[/p][p=30, 2, left]9>延时100us 以上；[/p][p=30, 2, left]10>清除显示；[/p][p=30, 2, left]11>延时10ms以上；[/p][p=30, 2, left]12>进入点设置；[/p][p=30, 2, left]13>初始化结束；[/p][p=30, 2, left]这里我遇到了一个小问题，我的液晶按照这个顺序进行初始化结果不正确，无法显示，最后我把调整了一下就可以了，调整后的顺序为：清除显示进入点设置显示开关控制，不知道是什么原因，知道的告诉我一声…[/p][p=30, 2, left]CODE://******************************************************* *//显示初始化函数//******************************************************* *void Display_Init(void){delay_ms(45); //延时45msPSB=1; //8位并行口//复位操作RST=1;delay(1);RST=0;delay(1);RST=1;delay(1);//功能设定LcdWcom(0x30); //设置为8位并行口，基本指令集delay(10);LcdWcom(0x30); //再次设置为8位并行口，基本指令集delay(5);// //显示开关控制// LcdWcom(0x0c); //游标显示关，正常显示，整体显示开// delay(10);//清除显示LcdWcom(0x01);delay_ms(12); //延时12ms//进入点设置LcdWcom(0x06); //设置为游标右移，DDRAM位地址加1，画面不移动delay(5);LcdWcom(0x0C); //开显示}[/p][p=30, 2, left]三、显示基本的字符和汉字[/p][p=30, 2, left]1、要想显示汉字或字符，首先要确定显示的位置，看看芯片说明书上关于屏幕地址的分配：[/p][p=30, 2, left]DDRAM位址.JPG[/p][p=30, 2, left]由于此液晶为128*64，即是横向128个点，竖向64个点，由于该液晶控制器支持的字符为8*16，汉字为16*16，因此只能显示四行，如果是汉字，为每行显示8个，如果是字符，每行显示16个。

带字库12864绘图说明一、用带字库12864LCD屏绘图首先要对其绘图寄存器GDRAM地址了解清楚。

如图所示绘图寄存器GDRAM地址由水平地址(LCD_X)和垂直地址（LCD_Y）组成；如上图所示，水平地址共有16个（0x80～0x8f）,其中上半屏起始地址为0X80,下半屏起始地址为0X88每个水平地址对应16列，上下半屏各有8个水平地址，所以一屏总共有128列.垂直地址共有32个（0x80～0x9f），因为上下半屏的垂直地址一样所以实际上一屏总共有64行。

特别注意：虽然一屏有128列，但并不是每列都有它的地址。

其实，从左往右每16列为一“大列”，有一个水平地址。

送数据时只要将该“大列”的水平地址和垂直地址送入12864，然后紧接这写如两个字节的内容，就可将这两个字节的内容显示在这一“大列”的16位上（先送高位，再送低位；显示时左面8位为高位）。

二、写入绘图RAM的步骤按照上面的步骤写了一个绘图地址的函数void wr_address( void)//送地址函数{write_com(0x34);//附加功能使能write_com(LCD_Y);//送入垂直地址write_com(LCD_X);//送入水平地址write_com(0x30);//禁止附加功能}下面是一个清屏函数（注意：绘图的清屏与显示汉字的清屏不同，手册中的清屏指令只能清楚DDRAM的内容，但无法清楚GDRAM的内容。

绘图清屏其实就是向GDRAM中写如0x00）void show3(void)//绘图清屏{uchar i,j,k;LCD_X=0X80;for(i=0;i<2;i++){LCD_Y=0X80;for(j=0;j<32;j++){wr_address();//写入起始地址for(k=0;k<16;k++)//连续写入16个字节（一行写满），每写入两个字节LCD_X会自动加1write_data(0x00);LCD_Y++;//垂直地址不会自动加1，写完一行后要程序换行}LCD_X=0X88;}write_com(0x36);write_com(0x30);}三、用带字库的LCD屏显示波形实例A、大致步骤1、绘图清屏2、AD转换器对波形采样，并将采样值定义在0～63之间，依次存入容量为128字节的一个数组中3、从数组中依次取出数据，送入GDRAMB、设计难点1、如何在屏上显示高低不同的点2、如何将不规则、无规律的点用字节的形式送显示3、怎样用AD转换的结果来控制显示的波形C、解决方案1、本次设计的核心思想就是将LCD屏看作一个128*64的点阵屏，从左往右循环送入uint code tab2[]={0x8000,0x4000,0x2000,0x1000,0x0800,0x0400,0x0200,0x0100,0x0080,0x0040,0x0020,0x0010,0x0008,0x0004,0x0002,0x000 1};的内容，这些点的高低由它们的垂直坐标LCD_Y决定；我们用AD 转换结果的128个字节的内容与128列一一对应，这写结果作为它们对应列上点的垂直坐标（注意，这些结果还要少做处理后才能作为垂直坐标，具体见下面程序）2、上面的做法会出现一个问题，那就是在一个“大列”中（一个水平坐标内）的16个点如果在同一行上出现两个以上的点，那么前面的点将不会显示（例如，在水平地址为0x80的这一“大列”中，第一列和第三列同在第三行，那么在显示第一列的点时地址为（0x80,0x82）的GDRAM中送入的数据是0x8000，而在显示第三列时，该GDRAM要送入的数据为0x2000；最终该GDRAM为0x2000，所以第一列的点在屏上就显示不出来了）。
