    Hi,

    You will always have random OUTPUT state at power on ...

    So, just Write

    GPIO = % xxxxxxxx

    BEFORE setting your Tris Register ...

    and do not forget your inputs will be floating for some ms at startup ( hardware pull up or down resistors to place, i.e. when driving Mosfets ...)

    EDIT : +1 with Sinoteq, then !!!

    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 " !!!

    Thanks guys, it worked like a charm. I'll have to add that to the mental archives for a standard approach.
