Arduino教程(提高篇)——驱动12864LCD模块

XXXXXXXXXXXXXXXXXXXXX/XXXXXXXXXXXXXXXXXXml
mini12864图:

001.jpg

mini12864可配合取模软件及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mini液晶屏成本相对较低,适用于各类仪器,小型设备的显示领域。

由于LCD驱动IC众多,这里我们仅以OPENJUMPERmini12864LCD为例教学,其他的LCD,你只需找到不同的库来驱动即可。

下面按步骤来驱动mini12864显示图片:

第一步:
下载取模软件

attachment icon 字模提取V2.2.zip 512.81KB ZIP 16次下载
(512.81 KB)

第二步:
处理图片,图片提取软件
attachment icon 图片提取软件.zip 730.20KB ZIP 18次下载 (731Kb),把你想要mini12864显示的图片,用软件处理为128*64.bmp

          如图:

002.jpg

第三步:
使用取模软件

            1、打开取模软件,新建图像,选择宽度128,高度64

2、打开你的图片,将做好的分辨率为128*64.bmp图导入

3、反向取模,由于此处用的液晶点阵为反向显示,这里的取模须反向取模。(取消这一步,使用程序库里函数也可以达到此效果反向显示)

4、
生成数组,并复制下面的数组

第四步:
下载库文件

attachment icon 库文件.zip 2.65KB ZIP 24次下载
,安装在arduino安装文件的libraries下面,打开IDE,敲入下面示例代码。


第五步:
复制刚才生成的数组,取代 bmp3[1024]里面的所有数组,编译并下载到您的arduino里。


#include "Lcd12864.h"
#include  "SPI.h"

unsigned char const bmp3[1024]={
0x00,0x00,0x00,0x00,0x00,0x00,0xC0,0xC0,0xF0,0x30,0x30,0x30,0x30,0x30,0x30,0x30,

void setup()
{
   lcd12864 x;
  XXXXmInit();
}
void loop()
{  
    lcd12864 x;
    x.PUTBMP(bmp3);             //液晶点阵正向显示1
    delay(1000);
    x.PUTREVERSEBMP(bmp3);        //反向显示1
    delay(1000);
}

第六步:mini12864arduino之间的接线。    
CS—— 8                   //片选 低有效
RST—— 9          //给芯片复位,低有效,如果不需软件给芯片复位,可不连接      
A0——10              //数据和命令选择,L 命令 H  数据
CLK——13           //时钟
MOSI——11         //数据
VCC——5V
GND——GND          //电源接线
LED——背光选择     //低有效
