      • setPort

        public void setPort​(char port,
                            short valueMask)
                     throws TinkerforgeException
        Sets the output value (high or low) for a port ("a" or "b") with a bitmask (8bit). A 1 in the bitmask means high and a 0 in the bitmask means low. For example: The value 15 or 0b00001111 will turn the pins 0-3 high and the pins 4-7 low for the specified port. All running monoflop timers of the given port will be aborted if this function is called. \note This function does nothing for pins that are configured as input. Pull-up resistors can be switched on with setPortConfiguration(char, short, char, boolean).
        Throws:
        TinkerforgeException
      • getPort

        public short getPort​(char port)
                      throws TinkerforgeException
        Returns a bitmask of the values that are currently measured on the specified port. This function works if the pin is configured to input as well as if it is configured to output.
        Throws:
        TinkerforgeException
      • setPortConfiguration

        public void setPortConfiguration​(char port,
                                         short selectionMask,
                                         char direction,
                                         boolean value)
                                  throws TinkerforgeException
        Configures the value and direction of a specified port. Possible directions are 'i' and 'o' for input and output. If the direction is configured as output, the value is either high or low (set as *true* or *false*). If the direction is configured as input, the value is either pull-up or default (set as *true* or *false*). For example: * ('a', 255, 'i', true) or ('a', 0b11111111, 'i', true) will set all pins of port A as input pull-up. * ('a', 128, 'i', false) or ('a', 0b10000000, 'i', false) will set pin 7 of port A as input default (floating if nothing is connected). * ('b', 3, 'o', false) or ('b', 0b00000011, 'o', false) will set pins 0 and 1 of port B as output low. * ('b', 4, 'o', true) or ('b', 0b00000100, 'o', true) will set pin 2 of port B as output high. Running monoflop timers for the selected pins will be aborted if this function is called.
        Throws:
        TinkerforgeException
      • getPortConfiguration

        public BrickletIO16.PortConfiguration getPortConfiguration​(char port)
                                                            throws TinkerforgeException
        Returns a direction bitmask and a value bitmask for the specified port. A 1 in the direction bitmask means input and a 0 in the bitmask means output. For example: A return value of (15, 51) or (0b00001111, 0b00110011) for direction and value means that: * pins 0 and 1 are configured as input pull-up, * pins 2 and 3 are configured as input default, * pins 4 and 5 are configured as output high * and pins 6 and 7 are configured as output low.
        Throws:
        TinkerforgeException
      • setDebouncePeriod

        public void setDebouncePeriod​(long debounce)
                               throws TinkerforgeException
        Sets the debounce period of the BrickletIO16.InterruptListener listener. For example: If you set this value to 100, you will get the interrupt maximal every 100ms. This is necessary if something that bounces is connected to the IO-16 Bricklet, such as a button.
        Throws:
        TinkerforgeException
      • setPortInterrupt

        public void setPortInterrupt​(char port,
                                     short 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: ('a', 129) or ('a', 0b10000001) will enable the interrupt for pins 0 and 7 of port a. The interrupt is delivered with the BrickletIO16.InterruptListener listener.
        Throws:
        TinkerforgeException
      • setPortMonoflop

        public void setPortMonoflop​(char port,
                                    short selectionMask,
                                    short valueMask,
                                    long time)
                             throws TinkerforgeException
        Configures a monoflop of the pins specified by the second parameter as 8 bit long bitmask. The specified pins must be configured for output. Non-output pins will be ignored. The third parameter is a bitmask with the desired value of the specified output pins. A 1 in the bitmask means high and a 0 in the bitmask means low. The forth parameter indicates the time that the pins should hold the value. If this function is called with the parameters ('a', 9, 1, 1500) or ('a', 0b00001001, 0b00000001, 1500): Pin 0 will get high and pin 3 will get low on port 'a'. In 1.5s pin 0 will get low and pin 3 will get high again. A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and an IO-16 Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and pin 0 set to high. Pin 0 will be high all the time. If now the RS485 connection is lost, then pin 0 will get low in at most two seconds.
        Throws:
        TinkerforgeException
      • setSelectedValues

        public void setSelectedValues​(char port,
                                      short selectionMask,
                                      short valueMask)
                               throws TinkerforgeException
        Sets the output value (high or low) for a port ("a" or "b" with a bitmask, according to the selection mask. The bitmask is 8 bit long and a 1 in the bitmask means high and a 0 in the bitmask means low. For example: The parameters ('a', 192, 128) or ('a', 0b11000000, 0b10000000) will turn pin 7 high and pin 6 low on port A, pins 0-6 will remain untouched. Running monoflop timers for the selected pins will be aborted if this function is called. \note This function does nothing for pins that are configured as input. Pull-up resistors can be switched on with setPortConfiguration(char, short, char, boolean).
        Throws:
        TinkerforgeException
      • getEdgeCount

        public long getEdgeCount​(short pin,
                                 boolean resetCounter)
                          throws TinkerforgeException
        Returns the current value of the edge counter for the selected pin on port A. You can configure the edges that are counted with setEdgeCountConfig(short, short, short). If you set the reset counter to *true*, the count is set back to 0 directly after it is read. .. versionadded:: 2.0.3$nbsp;(Plugin)
        Throws:
        TinkerforgeException
      • setEdgeCountConfig

        public void setEdgeCountConfig​(short pin,
                                       short edgeType,
                                       short debounce)
                                throws TinkerforgeException
        Configures the edge counter for the selected pin of port A. Pins 0 and 1 are available for edge counting. 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. .. versionadded:: 2.0.3$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|
