1. 引言

之前我们学了led灯（可以理解为一个点），然后后面学习了数码显示（可以理解我8条线组成的led灯组，能展示数字0~9和部分字母），上一次我们学习了LCD1602(可以理解为一个面，能展示数字和字母，有字库)。这次我们学习LCD12864(面更大，可展示全面的数字和字母，无字库)

2. 基础概念

点阵式液晶显示器LCD12864有两种：

1. 以KS0108 为主控芯片，不带字库 ，显示的字符或图形是由不同的点阵组成，点阵的获得可以借助于取模软件
2. 另外一种是ST7920为主控信息，带字符ASCII码和中文的点阵质控。

本文介绍的是KS0108为主控芯片的LCD12864的试用方法。

3. 外观和显示

3.1 外观和引脚

引脚功能：

引脚号	引脚符号	功能
第1脚	CS1	左半屏选择信号，低电平有效。
第2脚	CS2	右半屏选择信号，低电平有效。
第3脚	GND	电源地。
第4脚	VCC	电源正极。
第5脚	V0	对比度调整输入端。
第6脚	RS	数据/命令选择端，高电平选择数据寄存器，低电平选择命令寄存器。
第7脚	R/-W	读/写选择端，高电平读操作，低电平写操作。
第8脚	E	使能端当E端高电平时读取液晶模块的信息，当E端由高电平跳变成低电平时，液晶模块执行写操作。
第9～16脚	D0～D7	为8位双向数据线。
第17脚	RST	复位端，低电平复位，高电平正常工作。
第18脚	VOUT	LCD驱动负压输出端。
第19脚	BLA	背光源正极。
第20脚	BLK	背光源负极。

重点：RS 、R/-W、E 这三个引脚控制读写，控制命令或数据

3.2 点阵显示原理

• 两个控制模块，分别控制左半屏 和右半屏 ，每屏为64×64点阵。
• 每屏纵向8点为一页，从上到下分成8页，页号0 ~ 7。横向64个点，分成64列，列号0~63。
• 显示时以"页"为单位，每一页从0列到63列，一列8位，对应一个字节，上方为低位，下方为高位。
• 每屏总共8×64个字节，两屏总共2×8×64=1K个字节，对应内部的显示存储器。

字符或汉字转换成对应的点阵代码称为取模。取模可借助于取模软件，KS0108控制LCD12864的点阵显示方式在取模软件中称为列行式。对于8×16点阵的西文字符和16×16点阵的中文汉字，在LCD12864中实际占用2个"页"；操作时一般先写上面一页，再写下面一页，每一页从0列写到7（或者15）列，这样就完成一个字符（或者汉字）的显示。

字符"A" 和"杨"的点阵代码，取模方式选择列行式，数据格式采用C51格式。

 //A(0) 杨(1)

{0x00,0x00,0xC0,0x38,0xE0,0x00,0x00,0x00,0x20,0x3C,0x23,0x02,0x02,0x27,0x38,0x20},/*"A",0*/

{0x10,0x10,0xD0,0xFF,0x90,0x10,0x00,0x42,0xE2,0x52,0x4A,0xC6,0x42,0x40,0xC0,0x00
 0x04,0x03,0x00,0xFF,0x00,0x23,0x10,0x8C,0x43,0x20,0x18,0x47,0x80,0x40,0x3F,0x00},/*"杨",1*/

4. 指令（查询使用不要死记）

KS0108控制器 LCD12864 指令集 (图形点阵)

序号	指令功能	指令码 (二进制)	说明
1	显示开关	0000 1111 1 D	控制整体显示的开/关。D=1为开显示(0x3F)，D=0为关显示(0x3E)。不影响DDRAM中的数据。
2	设置显示起始行	11XX XXXX	设置显示屏顶部对应的DDRAM行地址，取值范围0~63。例如0xC0表示从第0行开始显示。可用于实现屏幕滚动效果。
3	设置页地址	10111 XXX	设置当前操作的页地址（X地址），取值范围0~7，对应显示屏的8个页（每页8行）。基础指令码为0xB8，加页号即可（如第2页为0xBA）。
4	设置列地址	01XX XXXX	设置当前操作的列地址（Y地址），取值范围0~63。基础指令码为0x40，加列偏移即可。每次读写数据后，列地址会自动加1。
5	读状态字	0 1 BF 0 ON/OFF RST 0 0 0 0	读取控制器内部状态。BF=1表示忙，此时不能进行除读状态外的其他操作；ON/OFF表示显示状态；RST表示复位状态。
6	写显示数据	1 0 D7 ... D0	将8位显示数据写入当前页地址和列地址所指向的DDRAM单元。写入后列地址自动加1。
7	读显示数据	1 1 D7 ... D0	从当前页地址和列地址所指向的DDRAM单元读出8位数据。读取后列地址自动加1。注意：进行有效读操作前，需先进行一次空读操作。

5. 编程

5.1 文字信息显示

【例】使用LCD12864的第一行显示自己名字，第二行显示自己的学号，第三行显示电话号码，第四行显示班级，要求：居中对齐，用C51编写相应程序。在Proteus中完成设计与仿真。

5.2 运行效果

6. 工具

• 仿真软件 proteus
• 开发软件 Keil
• 取字模1 点击下载
• 取字模2 点击下载（可取图片点阵图）

6.1PCtoLCD(取字模1) 使用方式

1. 下载后是一个zip文件，对zip文件进行解压得到解压文件
2. 双击执行文件
   
3. 打开取模软件后，输入需要取模的文字，例如'星游路' ，点击'生成字模'（默认是A51模式，即汇编语言模式）
   
4. 修改模式，点击'选项'，选择C51格式，点击确定，重新点击生成字模（就得到了C51格式的字模）
   

6.1转码221(取字模2) 使用方式

字模2更多的是当成图片来取点阵图。我们就以手写'星游路'为例。

1. 在白纸上写下你要取模的图形。
   
2. 使用电脑自带的画图工具，进行大小调整。（1. 截取要调整的文字，2，点击调整大小。3，目标是调整128*64 。先给水128.垂直暂不调整）
   
3. 拖拽画板到128 *64
   
4. 文件另存为单色图
   

5. 点击确定

6. 得到单色图（也可以是网上的卡通图片转单色图）

7. 双击取模软件

8. 点击'新建图像'， 输入 128 和64 。

9. 上传单色图

10. 生成字模

7. 总结
