    Hi, Steve

    Did you notice a 1K resistor had magically appeared in series with the trans. base ??? ...

    Strong coffee needed ... Malc is a one not so easy to follow !!!

    The output schematic can be enough for this time ... let's see one problem at a time !!!

    Inserting some PAUSE ( 100-200 ms ) between inputs pollings might do something interesting here ... let's try that first

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
