From a hardware perspective we are using a circuit as described above, with the addition of a ohm resistor followed by an LED thence to ground from on each of the sixteen outputs. Viewing Tweets won't unblock tronixstuff. For our last example — a demonstration of using port A as outputs and port B as inputs.
