AccelerometerListener

public AccelerometerListener(HB hb)

Method Detail

setRounding

public void setRounding(int resolution)

Set the resolution for all three axis to the number of decimal places set by resolution. A value of -1 will remove rounding

Parameters:

resolution - the number of decimal places to round to. -1 will be no rounding

scaleValue

public float scaleValue(double sensor_value,
                        double scaled_min,
                        double scaled_max)

Scale the values based on a maximum and minimum sensor value of 1 / -1 The value can be greater than scaled_min and scaled_max if sensor_value is greater than abs(1) ((scaled_max - scaled_min) * (sensor_value - sensor_min)) / (sensor_max - sensor_min) + scaled_min;

Parameters:

scaled_min - The value we want our standard minimum sensor value to become

sensor_value - The actual value of our sensor

scaled_max - The value we want our standard maximum sensor value to become

Returns:

the value scaled

sensorUpdated

public abstract void sensorUpdated(float x_val,
                                   float y_val,
                                   float z_val)

Sensor has been updated

Parameters:

x_val - x value of accelerometer

y_val - y value of accelerometer

z_val - z value of accelerometer
