public class LIS3L02AQAccelerometer
extends Accelerometer3D
implements IMeasurementRange, IScalarInputThresholdListener

Class to implement an accelerometer on the demo sensor board and provide access to it via the IAccelerometer3D interface. Provides methods specific to this particular accelerometer.

The LIS3L02AQ accelerometer can measure accelerations using either a 2G or 6G scale.

The accelerometer reports a voltage to indicate the acceleration along each axis. To convert this voltage to G's requires subtracting the zero acceleration voltage and then dividing by a gain constant:

Acceleration in G's = (Voltage - zero offset) / gain

A standard zero offset and gain are used by default, but since the accelerometer in each SPOT can differ by up to 10% from the default it is best to calibrate each SPOT and save the offset and gain for each axis and scale. An application to calibrate the accelerometer is provided with the SPOT Demos.

Note: By default the maximum rate that the accelerometer can be read is ~58 Hz, i.e. reading all three axis every 17.1 milliseconds. For faster readings the ADT7411 must be set to use its fast conversion rate that will allow reading all three axis every 0.579 milliseconds (or 1667 Hz). Note that setting the ADT7411 to fast mode may cause readings of A0 to become inaccurate.
