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。

然后点载入图片，

点击数据保存，得到C语言文件：

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：

#小五义：http://www.cnblogs.com/xiaowuyi

#define Register_Z0 0x36
#define Register_Z1 0x37
#define AR_SIZE( a ) sizeof( a ) / sizeof( a[0] )

  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[10];
  double tempy=0;
  char stry[10];
  double tempz=0;
  char strz[10];
  
  LCDA.CLEAR();//清屏
  LCDA.DisplayString(2,2,show1x,AR_SIZE(show1x)); 
  delay(1000);
  while(1)
  {
    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;
    }

    {
      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;

    }  
  }

 
}

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。

LabVIEW控制Arduino实现超声波测距（进阶篇—5）
超声波测距是一种传统而实用的非接触测量方法，与激光、涡流和无线电测距方法相比，具有不受外界光及电磁场等因素影响的优点，在比较恶劣的环境中也具有一定的适应能力，且结构简单、成本低，因此在工业控制、建筑测量、机器人定位方面有广泛的应用。

数据采集 API C#
“Unity开发也能跟硬件联动”--快来看看吧(串口通信)
简单的串口通信工具，基于C#应用程序WinFrom实现 串口介绍 串行接口简称串口，也称串行通信接口或串行通讯接口（通常指COM接口），是采用串行通信方式的扩展接口。（至于再详细，自己百度） 串口应用 工业领域使用较多，比如:数据采集，设备控制等等，好多都是用串口通信来实现！你要是细心的话，你会发现，目前家用国网智能电能表就具备RS485通信总线（串行总线的一种）与RS232可以相互转化（当然一般，非专业的谁也不会闲的蛋疼，趴电表上瞎看,最多也就看看走了多少度电）
