      • getValue

        public int getValue()
                     throws TinkerforgeException
        Returns the input value with a bitmask. The bitmask is 16bit long, *true* refers to high and *false* refers to low. For example: The value 3 or 0b0011 means that pins 0-1 are high and the other pins are low. If no groups are used (see setGroup(char[])), the pins correspond to the markings on the IndustrialDigital In 4 Bricklet. If groups are used, the pins correspond to the element in the group. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.
        Throws:
        TinkerforgeException
      • setGroup

        public void setGroup​(char[] group)
                      throws TinkerforgeException
        Sets a group of Digital In 4 Bricklets that should work together. You can find Bricklets that can be grouped together with getAvailableForGroup(). The group consists of 4 elements. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15. Each element can either be one of the ports ('a' to 'd') or 'n' if it should not be used. For example: If you have two Digital In 4 Bricklets connected to port A and port B respectively, you could call with ``['a', 'b', 'n', 'n']``. Now the pins on the Digital In 4 on port A are assigned to 0-3 and the pins on the Digital In 4 on port B are assigned to 4-7. It is now possible to call getValue() and read out two Bricklets at the same time. Changing the group configuration resets all edge counter configurations and values.
        Throws:
        TinkerforgeException
      • getAvailableForGroup

        public short getAvailableForGroup()
                                   throws TinkerforgeException
        Returns a bitmask of ports that are available for grouping. For example the value 5 or 0b0101 means: Port A and port C are connected to Bricklets that can be grouped together.
        Throws:
        TinkerforgeException
      • setInterrupt

        public void setInterrupt​(int interruptMask)
                          throws TinkerforgeException
        Sets the pins on which an interrupt is activated with a bitmask. Interrupts are triggered on changes of the voltage level of the pin, i.e. changes from high to low and low to high. For example: An interrupt bitmask of 9 or 0b1001 will enable the interrupt for pins 0 and 3. The interrupts use the grouping as set by setGroup(char[]). The interrupt is delivered with the BrickletIndustrialDigitalIn4.InterruptListener listener.
        Throws:
        TinkerforgeException
      • getEdgeCount

        public long getEdgeCount​(short pin,
                                 boolean resetCounter)
                          throws TinkerforgeException
        Returns the current value of the edge counter for the selected pin. You can configure the edges that are counted with setEdgeCountConfig(int, short, short). If you set the reset counter to *true*, the count is set back to 0 directly after it is read. The edge counters use the grouping as set by setGroup(char[]). .. versionadded:: 2.0.1$nbsp;(Plugin)
        Throws:
        TinkerforgeException
      • setEdgeCountConfig

        public void setEdgeCountConfig​(int selectionMask,
                                       short edgeType,
                                       short debounce)
                                throws TinkerforgeException
        Configures the edge counter for the selected pins. A bitmask of 9 or 0b1001 will enable the edge counter for pins 0 and 3. The edge type parameter configures if rising edges, falling edges or both are counted if the pin is configured for input. Possible edge types are: * 0 = rising * 1 = falling * 2 = both Configuring an edge counter resets its value to 0. If you don't know what any of this means, just leave it at default. The default configuration is very likely OK for you. The edge counters use the grouping as set by setGroup(char[]). .. versionadded:: 2.0.1$nbsp;(Plugin)
        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|
        Specified by:
        getIdentity in class Device
        Throws:
