HMC5883L driver for Android Things
================================
This driver include 3-axis magnetometer. There is no warranty for this driver. NOT USE IN PRODUCTION!!
How to use the driver
---------------------
### Sample usage
Manual usage
```java
import com.cacaosd.android.things.contrib.driver.hmc5883l;
// Access the environmental sensor:
HMC5883L hmcl5883l;
try {
hmcl5883l = new HMC5883L(i2cBusName);
hmcl5883l.setSamplesAvarage(SAMPLES_AVARAGE_8);
hmcl5883l.setOutputRate(OUTPUT_RATE_4);
hmcl5883l.setMeasurementMode(MEASUREMENT_NORMAL);
hmcl5883l.setMeasurementGain(GAIN_1090);
hmcl5883l.setOperationMode(OPERATION_MODE_CONT);
} catch (IOException e) {
// error.
}
try {
float[] magnitudes = hmcl5883l.getMagnitudes();
} catch (IOException e) {
// error reading
}
try {
hmcl5883l.close();
} catch (IOException e) {
// error closing sensor
}
```
You can register Android Sensor Service like this.
```java
SensorManager mSensorManager = getSystemService(Context.SENSOR_SERVICE);
SensorEventListener mListener = ...;
HMC5883LSensorDriver mSensorDriver;
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mSensorManager.registerDynamicSensorCallback(new SensorManager.DynamicSensorCallback() {
@Override
public void onDynamicSensorConnected(Sensor sensor) {
if (sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD) {
mSensorManager.registerListener(MagnetometerActivity.this,
sensor, SensorManager.SENSOR_DELAY_NORMAL);
}
}
});
try {
mSensorDriver = new HMC5883LSensorDriver(BoardDefaults.getI2CPort());
mSensorDriver.registerMagmetormeterSensor();
} catch (IOException e) {
Log.e(TAG, "Error configuring sensor", e);
}
}
if (mSensorDriver != null) {
mSensorManager.unregisterListener(this);
mSensorDriver.unregisterMagmetormeterSensor();
try {
mSensorDriver.close();
} catch (IOException e) {
Log.e(TAG, "Error closing sensor", e);
} catch (Exception e) {
e.printStackTrace();
} finally {
mSensorDriver = null;
}
}
```
