Class AccelHTSensor

java.lang.Object
  lejos.nxt.I2CSensor
      lejos.nxt.addon.AccelHTSensor

All Implemented Interfaces:

SensorConstants, Accelerometer

public class AccelHTSensor
extends I2CSensor
implements Accelerometer

Class to access the HiTechnic NXT Acceleration / Tilt Sensor (NAC1040). Some sensors seem to be badly calibrated, so 0 is not always level.

Method Detail

getXAccel

public int getXAccel()

Acceleration along X axis. Positive or negative values. A value of 200 is equivalent to 1g.

Specified by:

getXAccel in interface Accelerometer

Returns:

x-axis acceleration or ERROR.

getYAccel

public int getYAccel()

Acceleration along Y axis. Positive or negative values. A value of 200 is equivalent to 1g.

Specified by:

getYAccel in interface Accelerometer

Returns:

y-axis acceleration or ERROR.

getZAccel

public int getZAccel()

Acceleration along Z axis. Positive or negative values. A value of 200 is equivalent to 1g.

Specified by:

getZAccel in interface Accelerometer

Returns:

z-axis acceleration or ERROR.

getAllAccel

public boolean getAllAccel(int[] dst,
                           int off)

Reads all 3 acceleration values into the given array. Elements off+0, off+1, and off+2 are filled with X, Y, and Z axis.

Parameters:

dst - destination array.

off - offset

Returns:

true on success, false on error
