Constructor Detail

TouchMUX

public TouchMUX(AnalogPort port)

Create a object to provide access to a touch sensor multiplexer

Parameters:

port - The NXT sensor port to which the multiplexer is attached

TouchMUX

public TouchMUX(Port port)

Create a object to provide access to a touch sensor multiplexer

Parameters:

port - The NXT sensor port to which the multiplexer is attached

Method Detail

getInstance

public Touch getInstance(int id)

Return a Touch interface providing access to the sensor specified by the given id.

Parameters:

id - a number between 0..NUMBER_OF_SENSORS-1

Returns:

the requested Touch interface

readSensors

public int readSensors()

Read the touch multiplexer and return a bit mask showing which sensors are currently pressed. Returns ID_T1 if T1 is pressed, ID_T2 if T2 is pressed and ID_T3 id T3 is pressed. If more then one sensor is pressed the return will be an or of the values.

Returns:

bit mask showing which sensor buttons are pressed.
