    欢迎加入讨论群 64770604

    一、本次实验所需器材

    1、Arduino UNO板 https://item.taobao.com/item.htm?spm=a1z10.5-c-s.w4002-15820725129.16.AtgoEm&id=545093340395

    2、12864显示器（带中文字库）。

    3、ADXL345加速度传感器：ADI公司推出的一款小而薄的低功耗3轴加速度计，分辨率高（13位），测量范围达±16g（1g显示数字为256）。数字输出数据为16位二进制补码格式，可通过SPI（3线或4线）或I2C数字接口访问。该系列传感器还有ADXL335、ADXL346等。这种传感器被广泛应用，如用来制作计步器（http://www.21ic.com/app/control/201011/69048.htm）等。

    4、面包板：2个

    5、电阻：1KΩ电阻2个。

    二、硬件连接方法

    三、实验过程

    1、12864显示文字和图像

    （1）12864在显示汉字时，需要用到汉字的内码，我使用的软件可从这里下载http://www.kuaipan.cn/file/id_749007936689913.htm?source=1。如汉字“开始”对应内码是BFAA和CABC，那么就转换成0xBF,0xAA,0xCA,0xBC。

    （2）12864显示图像时，只能显示位图。一般图片可通过ps转换为位图，具体方法可百度。获取位图后，再利用图片取模软件（http://www.kuaipan.cn/file/id_749007936689914.htm?source=1）进行转化。如图片：

    9999

    打开图片取模软件，首先进行参数设置，转出格式选C语言，输出大小128*64，点参数确认。

    未标题-2 拷贝

    然后点载入图片，

    333333

    点击数据保存，得到C语言文件：

    这里用的LCD12864RSPI.h这个库是针对1.0以上版本IDE的，下载：http://www.kuaipan.cn/file/id_749007936689932.htm?source=1。

    实现视频：

    2、ADXL345获取加速度值

    通过以下代码，12864显示器上会显示出X、Y、Z的值：

    #小五义：http://www.cnblogs.com/xiaowuyi 
    #include <Wire.h>  //调用arduino自带的I2C库
#include <LCD12864RSPI.h>
 
#define Register_ID 0
#define Register_2D 0x2D
#define Register_X0 0x32
#define Register_X1 0x33
#define Register_Y0 0x34
#define Register_Y1 0x35
#define Register_Z0 0x36
#define Register_Z1 0x37


unsigned char showx[]="X=";
unsigned char showy[]="Y=";
unsigned char showz[]="Z=";

 
int ADXAddress = 0xA7>>1;  //转换为7位地址
int reading = 0;
int val = 0;
int X0,X1,X_out;
int Y0,Y1,Y_out;
int Z1,Z0,Z_out;
double Xg,Yg,Zg;
 
void setup()
{
  LCDA.Initialise(); // 屏幕初始化
  delay(100);
  Wire.begin();  //初始化I2C
  delay(100);
  Wire.beginTransmission(ADXAddress);
  Wire.write(Register_2D);
  Wire.write(8);
  Wire.endTransmission();
}
 
void loop()
{
  double tempx=0;
  char strx[5];
  double tempy=0;
  char stry[5];
  double tempz=0;
  char strz[5];
  
  Wire.beginTransmission(ADXAddress);
  Wire.write(Register_X0);
  Wire.write(Register_X1);
  Wire.endTransmission();
  Wire.requestFrom(ADXAddress,2);
  if(Wire.available()<=2);
  {
    X0 = Wire.read();
    X1 = Wire.read();
    X1 = X1<<8;
    X_out = X0+X1;
  }
 
  Wire.beginTransmission(ADXAddress);
  Wire.write(Register_Y0);
  Wire.write(Register_Y1);
  Wire.endTransmission();
  Wire.requestFrom(ADXAddress,2);
  if(Wire.available()<=2);
  {
    Y0 = Wire.read();
    Y1 = Wire.read();
    Y1 = Y1<<8;
    Y_out = Y0+Y1;
  }
 
  Wire.beginTransmission(ADXAddress);
  Wire.write(Register_Z0);
  Wire.write(Register_Z1);
  Wire.endTransmission();
  Wire.requestFrom(ADXAddress,2);
  if(Wire.available()<=2);
  {
    Z0 = Wire.read();
    Z1 = Wire.read();
    Z1 = Z1<<8;
    Z_out = Z0+Z1;
  }
 
  Xg = X_out/256.00;//把输出结果转换为重力加速度g,精确到小数点后2位。
  Yg = Y_out/256.00;
  Zg = Z_out/256.00;
  LCDA.CLEAR();//清屏
  
  LCDA.DisplayString(0,0,showx,2);//使屏幕显示文字X=
  tempx=Xg;
  dtostrf(tempx,5,2,strx);
  LCDA.DisplayString(0,3,(unsigned char *)strx,6);
  
  LCDA.DisplayString(1,0,showy,2);//使屏幕显示文字Y=
  tempy=Yg;
  dtostrf(tempy,5,2,stry);
  LCDA.DisplayString(1,3,(unsigned char *)stry,6);

  LCDA.DisplayString(2,0,showz,2);//使屏幕显示文字Z=
  tempz=Zg;
  dtostrf(tempz,5,2,strz);
  LCDA.DisplayString(2,3,(unsigned char *)strz,6);  

  delay(300);  //延时0.3秒，刷新频率这里进行调整
 
}

    实现视频效果：

    3、利用ADXL345实现重力感应效果

    实验中，当向某一方向转动ADXL345模块时，12864屏幕会显示转动方向，如果能配合上动画效果会更加明显，这里只是用文字进行了显示。

    代码如下：
