    This might help you out a little

    BS2 Syntax Manuel

    The BS2P40 uses a serial shift register for the AUX pins
    '
    Its well documented in the above Manuel under BS2P40
    '
    There is also some special command sets unique to the BS2P40 to easily get access to the AUX pins
    '
    I really like this chip when I need a few extra I/O pins
    '
    I short little read should have you up and running in no time.

    If your still struggling after the read, Just reply back to your post here, And we'll help you figure it out.

    If you have a BS2 Pro. Dev. Board the pin-outs are different with the BS2P40 then with other BS2's
    '
    Its very confusing if you haven't read the Manuel first.

    Have Fun
