# ADXL362 Java and AndroidThings Library

ADXL362B Accelerometer Java and Android Things Library



# Java Documentation 



This is a pure Java interfacing of Accelerometer ADXL362 with Raspberry Pi using pi4j on Raspbian.

This should work on any other OS for Raspberry Pi (or any other development platform, may be), which have Oracle JDK and pi4j support.

X, Y, Z axis values are obtained as integers.

Temperature values are obtained as integers.



## Requirements

 

 1. Raspberry Pi with raspbian

 2. Orcale JDK (latest is recommended)

 3. pi4j. Installation instructions [here](http://pi4j.com/install.html)



## Sample usage



```java

try {

     Adxl362 adxl362 = new Adxl362(SpiChannel.CS0, 5000000, SpiMode.MODE_0);

     adxl362.doSoftReset();

     adxl362.beginMeasurement();

     while(true) {

                 System.out.println("X is: " + adxl362.readXData() + ", Y is: " + adxl362.readYData() + ", Z is: " + adxl362.readZData() + ", TEMP is: " + adxl362.readTempData());

                Thread.sleep(1000);

     }

    } catch(IOException | InterruptedException e) {

            e.printStackTrace();

        }

```



# Android Things Documentation



##How to use the library



1. Clone the repository `git clone https://github.com/vishal-android-freak/ADXL362-Interfacing-Library.git`

2. Clone the sample project template `https://github.com/androidthings/new-project-template.git` for android things or create your own project in Android studio following https://developer.android.com/things.

3. In Android Studio, go to File > New > Import Module.

4. Browse for the **ADXL362-Interfacing-Library** cloned folder.

5. In the 'Module name' section type `:adxl`.

6. Right click on the **app** folder and select 'Open Module Settings'.

7. Go to the 'Dependencies' section and click on the '+' and select 'Module dependency'.

8. Select ':adxl' and click Ok. Done!



##Sample Usage



```java



import vaf.vishal.Adxl362;



.....



// Access the environmental sensor directly:



Adxl362 adxl;



try {

    aadxl = new Adxl362("SPI0.0", 5000000, SpiDevice.MODE0);

} catch(IOException e) {

  // couldn't configure the device...

}



//Read X, Y, Z axis and Temperature sensor values values in centimeters.



try {

    float[] values = adxl.readXYZTempData();

    Log.d("ADXL", "X is: " + values[0] + ", Y is: " + values[1] + ", Z is: " + values[2] + ", TEMP is: " + values[3]);

} catch(IOException e) {

  //error reading values.

}



//close the accelerometer after finished.

try {

    adxl.close();

} catch(IOException e) {

  //error closing sensor.

}



```



If you need to read sensor values continuously, you can register the Hcsr04 with the system and listen for sensor values using the [Sensor APIs](https://developer.android.com/guide/topics/sensors/sensors_overview.html)



```java



SensorManager mSensorManager = getSystemService(Context.SENSOR_SERVICE);

SensorEventListener mListener = ...;

Adxl362AccelerometerDriver mSensorDriver;



mSensorManager.registerDynamicSensorCallback(new SensorManager.DynamicSensorCallback() {

    @Override

    public void onDynamicSensorConnected(Sensor sensor) {

          mSensorManager.registerListener(mListener, sensor,

                  SensorManager.SENSOR_DELAY_NORMAL);

    }

});



try {

    mSensorDriver = new Adxl362AccelerometerDriver("SPI0.0", 5000000, SpiDevice.MODE0);

    mSensorDriver.register();

} catch (IOException e) {

    // Error configuring sensor

}



// Unregister and close the driver when finished:



mSensorManager.unregisterListener(mListener);

mSensorDriver.unregister();

try {

    mSensorDriver.close();

} catch (IOException e) {

    // error closing sensor

}



```
