一、本次实验所需器材

1、Arduino UNO板

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。

然后点载入图片,

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:

#define Register_Y1 0x35

#define Register_Z0 0x36

#define Register_Z1 0x37

#define AR_SIZE( a ) sizeof( a ) / sizeof( a[0] )

实验效果:

 

从视频来看,当ADXL345模块平放在桌面时,屏幕显示中心,当向上、下、左、右等八个方向转动时,屏幕会依次显示向上、向下、向左、向右等。
