Android Things Bosh BMP85/BMP180 Driver Example
##Driver for BMP85/BMP180 for Android Things
##Example how to use BMP85/BMP180 with Android Things
### BMP180 sensor connection
### One can use the sensor directly without SensorManager
```java
private Bmp180 mBmp180;
private static final String I2C_BUS = "I2C1";
private void initSensor(){
mBmp180 = new Bmp180(I2C_BUS);
}
private void readData(){
try {
float temp = mBmp180.readTemperature();
float press = mBmp180.readPressure();
double alt = mBmp180.readAltitude();
Log.d(TAG, "loop: temp " + temp + " alt: " + alt + " press: " + press);
} catch (IOException e) {
Log.e(TAG, "Sensor loop error : ", e);
}
}
private void closeSensor(){
try {
mBmp180.close();
} catch (IOException e) {
Log.e(TAG, "closeSensor error: ", e);
}
mBmp180 = null;
}
```
### You can also use this driver with SensorManager
Registers the sensor and attach the listener
```java
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mSensorManager.registerDynamicSensorCallback(new SensorManager.DynamicSensorCallback() {
@Override
public void onDynamicSensorConnected(Sensor sensor) {
if (sensor.getType() == Sensor.TYPE_DEVICE_PRIVATE_BASE) {
if (sensor.getStringType().equalsIgnoreCase(Bmp180SensorDriver.BAROMETER_SENSOR)) {
Log.i(TAG, "Barometer sensor connected");
mSensorManager.registerListener(mListener,
sensor, SensorManager.SENSOR_DELAY_NORMAL);
}
}
}
});
try {
mSensorDriver = new Bmp180SensorDriver(I2C_PORT);
mSensorDriver.registerBarometerSensor();
} catch (IOException e) {
Log.e(TAG, "Error configuring sensor ", e);
}
```
Receives data through SensorEventListener
```java
@Override
public void onSensorChanged(SensorEvent event) {
float data[] = Arrays.copyOf(event.values, 3);
Log.i(TAG, "Pressure: " + data[0]);
Log.i(TAG, "Temperature: " + data[1]);
Log.i(TAG, "Altitude: " + (Math.round(data[2] * 10) / 10.0F));
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
Log.i(TAG, "sensor accuracy changed: " + accuracy);
}
```
