    • 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.
