液晶显示模块、LCD12864、SPI、产品简介、产品参数、使用说明、应用样例

概述

LCD12864模块是一款基于12864液晶显示器开发的显示模块。考虑到LCD12864显示器在并行数据传输模式下的使用难度较高,驱动代码较为复杂,我们开发了这款SPI为接口的显示模块。
12864带中文字库液晶显示器，可配合各种单片机可完成中文汉字、英文字符和图形显示，更适合Arduino做显示相关的互动作品，该点阵的屏显成本相对较低，适用于各类仪器，小型设备的显示领域。
显示屏在显示汉字、图片时，需要专门的软件先对汉字以及图片进行处理。

技术规格

工作电压：2.7~5v
通讯方式：并行IO控制
白色字符蓝色背景
控制器：ST7920
外形尺寸：93x70mm

LCD12864RSPI库与U8glib库使用指南

这款显示屏可以使用不同的库函数来显示，分别是LCD12864RSPI库函数和U8glib.h库函数。其中8glib.h库在中文时，可以设置字体类型，而LCD12864RSPI库不可以，下面分别介绍使用不同的库来显示图片、中文和字符。
如果想方便快捷的显示多个中文，建议使用12864SPI库函数。如果想对显示字符的字体、颜色等修改，建议使用U8glib库函数。

U8glib库的使用

1.接线图

引脚	接线
VSS	GND
VDD	5V
RS	模拟口A3
R/W	模拟口A2
E	模拟口A4
PSB	GND
BLA	5V
BLK	GND

"U8glib 接线"

2.显示字符

（1）接线图

参考上面的接线图

（2）演示字符显示代码

    #include "U8glib.h"
    U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9);  // SPI Com: SCK = en = 18=A4, MOSI = rw = 16=A2, CS = di = 17==A3
    void draw(void) {
      u8g.setFont(u8g_font_unifont);
      u8g.drawStr( 0, 22, "Hello World!");
    }

    void setup(void) {

    }

    void loop(void) {
      // picture loop
      u8g.firstPage();
      do {
        draw();
      } while( u8g.nextPage() );
    }

3.显示图片

（1）图片转换

第一：打开图形转换软件，设置模式为图形模式。

第二：设置参数为C5I

第三：打开要转换的图像，图像格式为位图（bmp）

第四：然后点击生成字模即可，最后把生成的字模放入一个字符数组里面。

（2）接线

与上面接线的方式相同

（3）演示显示图片代码

该显示屏需用用到U8glib库文件，库及其相关资料

    #include "U8glib.h"
    U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9);  //SPI Com: SCK =DB0 = 13, MOSI =DB1 = 11, CS = 10, A0  = DC= 9

      u8g.drawBitmapP( 0, 0, 16, 64, rook_bitmap);

    }

    void setup(void) {
    }

    void loop(void) {
      // picture loop
      u8g.firstPage();
      do {

      } while( u8g.nextPage() );

      // rebuild the picture after some delay
      delay(1000);
    }
    }

4.显示中文

（1）汉字转换

第一：打开PCtoLCD2002软件，选择模式为字符模式。

第二：在文本框中输入字符“人”，设置参数为C5I，点击生成字模，最后把生成的字模放入一个字符数组里面。

（2）接线图

与上面的接线图相同

（3）演示显示屏显示汉字“人”代码

显示汉字同样需要用到U8glib库函数，#库及其相关资料下载

    #include "U8glib.h"//库函数
    U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9);  // SPI Com: SCK = 13, MOSI = 11, CS = 10, A0 = 9 芯片类型及其对应的接线方式
    const uint8_t rook_bitmap[] PROGMEM = {
    0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,
    0x01,0x00,0x01,0x00,0x02,0x80,0x02,0x80,
    0x04,0x40,0x04,0x40,0x08,0x20,0x08,0x20,
    0x10,0x10,0x20,0x08,0x40,0x04,0x80,0x02,/*"人",0*/
    };
    void draw(void) {
      // graphic commands to redraw the complete screen should be placed here
      u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap);//第0行0列开始显示文字，生成的汉字“人”大小为16*16，所以后面的两个参数为（16/8,16）.

    }

    void setup(void) {
    }

    void loop(void) {
      // picture loop
      u8g.firstPage();
      do {
        draw();
      } while( u8g.nextPage() );
      // rebuild the picture after some delay
      delay(1000);
    }

（4）多个汉字显示代码注意事项

该取模软件，在生成字模时每个汉字会单独生成一个字模对应的数据，在显示多个汉字时，需要单独显示每个汉，即多次调用u8g.drawBitmapP( );这个函数。

（5）多个汉字显示代码演示

    #include "U8glib.h"
    U8GLIB_NHD27OLED_2X_BW u8g(13, 11, 10, 9);  // SPI Com: SCK = 13, MOSI = 11, CS = 10, A0 = 9

    };
    const uint8_t rook_bitmap3[] PROGMEM = {
    0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,
    0x01,0x00,0x01,0x00,0x02,0x80,0x02,0x80,

    };
    void draw(void) {
      // graphic commands to redraw the complete screen should be placed here
      u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap1);//0行0列显示“机”
        u8g.drawBitmapP( 16, 0, 2, 16, rook_bitmap2);//0行16列显示“器”
         u8g.drawBitmapP( 32, 0, 2, 16, rook_bitmap3);//0行32列显示“人”
    }

    void setup(void) {
    }

    void loop(void) {
      // picture loop
      u8g.firstPage();
      do {
        draw();
      } while( u8g.nextPage() );

      // rebuild the picture after some delay
      delay(1000);
    }

5.部分代码解释

u8g.drawStr( m, n, str);//m代表的是第m列，n代表的是第n行，str是要显示的字符串
u8g.drawBitmapP( m, n, x, y, str);//m代表的是第m列，n代表的是第n行，x代表的是生成字模点阵时的列数除以8，y代表的是点阵行数，str是要显示的字符串

例如显示汉字“人”u8g.drawBitmapP( 0, 0, 2, 16, rook_bitmap);//在生成字模时大小为16*16，那么x=16/2;y就是第二个16.

2.LCD12864RSPI显示字符

（1）接线

与上面12864SPI接线方式相同

（2）演示显示字符代码

    #include "LCD12864RSPI.h"
    #define AR_SIZE( a ) sizeof( a ) / sizeof( a[0] )
    unsigned char show[]="dfrobot.com";
    void setup()
    {
    LCDA.Initialise(); // 屏幕初始化
    delay(100);
    }

    void loop()
    {
    LCDA.CLEAR();//清屏
    delay(100);

    LCDA.DisplayString(2,1,show,AR_SIZE(show));;//第三行第二格开始，显示网址dfrobot.com/
    delay(5000);
    }

3.LCD12864RSPI显示汉字

（1）汉字解码方法

打开汉字解码软件，在待处理=字符串中输入要解码的汉字，点击转换即可，例如：

（2）连线图

参考上面12864SPI的连线图

（3）LCD12864RSPI 文字演示代码

    #include "LCD12864RSPI.h"
    #define AR_SIZE( a ) sizeof( a ) / sizeof( a[0] )
    unsigned char show[]= { 0xD6, 0xC7, 0xCE, 0xBB,  0xBB, 0xFA, 0xC6, 0xF7, 0xC8, 0xCB  };  //智位机器人
    void setup()
    {
    LCDA.Initialise(); // 屏幕初始化
    delay(100);
    }

    void loop()
    {
    LCDA.CLEAR();//清屏
    delay(100);
    LCDA.DisplayString(0,2,show,AR_SIZE(show));//第一行第三格开始，显示文智位机器人
    delay(5000);
    }

4.LCD12864RSPI 显示图片

（1）图片转换

第一：先打开photoshop，新建文档，大小为128*64，图片做好之后，保存格式为位图。

新建图片

第二：打开图片取模软件，先设置参数，选择c语言，输出大小X为128，Y为64。

第三：载入制作好或者已有的位图图片。

第四：保存数据，选择适当的位置，并给生成数据的文档命名。

第五：打开保存生成数据的文档，并将其生成的字符数组复制到代码里面。

    }

    void loop()
    {

    LCDA.DrawFullScreen(logo0);
    delay(5000);
    }

4.部分代码解释

LCDA.Initialise(); // 屏幕初始化
LCDA.CLEAR();//清屏
LCDA.DisplayString(m,n,str,length));//m代表的是行，n代表的是列，str代表的是要显示内容的名字，length是字符串的长度
LCDA.DrawFullScreen(logo0)//满屏显示内容
