                                         IPConnection ipcon)

      • setSegments

        public void setSegments​(short[] segments,
                                short brightness,
                                boolean colon)
                         throws TinkerforgeException
        The 7-segment display can be set with bitmaps. Every bit controls one segment: .. image:: /Images/Bricklets/bricklet_segment_display_4x7_bit_order.png :scale: 100 % :alt: Bit order of one segment :align: center For example to set a "5" you would want to activate segments 0, 2, 3, 5 and 6. This is represented by the number 0b01101101 = 0x6d = 109. The brightness can be set between 0 (dark) and 7 (bright). The colon parameter turns the colon of the display on or off.
        Throws:
        TinkerforgeException
      • startCounter

        public void startCounter​(short valueFrom,
                                 short valueTo,
                                 short increment,
                                 long length)
                          throws TinkerforgeException
        Starts a counter with the *from* value that counts to the *to* value with the each step incremented by *increment*. *length* is the pause between each increment. Example: If you set *from* to 0, *to* to 100, *increment* to 1 and *length* to 1000, a counter that goes from 0 to 100 with one second pause between each increment will be started. Using a negative increment allows to count backwards. You can stop the counter at every time by calling setSegments(short[], short, boolean).
        Throws:
        TinkerforgeException
      • getCounterValue

        public int getCounterValue()
                            throws TinkerforgeException
        Returns the counter value that is currently shown on the display. If there is no counter running a 0 will be returned.
        Throws:
        TinkerforgeException
      • getIdentity

        public Device.Identity getIdentity()
                                    throws TinkerforgeException
        Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier. The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'. The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|
