Interface Accelerometer

All Superinterfaces:

Configurable<Accelerometer.ConfigEditor<? extends Accelerometer.ConfigEditor>>, MetaWearBoard.Module

All Known Subinterfaces:

AccelerometerBma255, AccelerometerBmi160, AccelerometerBmi270, AccelerometerBosch, AccelerometerMma8452q

public interface Accelerometer
extends MetaWearBoard.Module, Configurable<Accelerometer.ConfigEditor<? extends Accelerometer.ConfigEditor>>

Measures sources of acceleration, such as gravity or motion. This interface is provides general access to an accelerometer. If you know specifically which accelerometer is on your board, use the appropriate subclass instead.

Method Detail

acceleration

Accelerometer.AccelerationDataProducer acceleration()

Get an implementation of the Accelerometer.AccelerationDataProducer interface

Returns:

AccelerationDataProducer object

packedAcceleration

AsyncDataProducer packedAcceleration()

Variant of acceleration data that packs multiple data samples into 1 BLE packet to increase the data throughput. Only streaming is supported for this data producer.

Returns:

AsyncDataProducer object for packed acceleration data

start

void start()

Switch the accelerometer into active mode

stop

void stop()

Switch the accelerometer into standby mode

getOdr

float getOdr()

Get the output data rate. The returned value is only meaningful if the API has configured the sensor

Returns:

Selected output data rate

getRange

float getRange()

Get the data range. The returned value is only meaningful if the API has configured the sensor

Returns:

Selected data range

pullConfigAsync

bolts.Task<java.lang.Void> pullConfigAsync()

Pulls the current accelerometer output data rate and data range from the sensor

Returns:

Task that is completed when the settings are received
