    1 - What are you using for the power supply?

    2 - Do you have decoupling cap close to VDD (to GND)?

    Question

    Hi,

    adding to Paul's ( good !!! ) questions ...

    What kind of load do you place on your outputs ( LEDs Ok, I wonder ! , but current = ? series resistor = ? )

    What kind of supply do yo have provided ??? ( a 6 LR 61 batt . ... joking ! )

    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 " !!!

    Ahh.. I rearranged the board and forgot to put the cap back.. i gotta go find that -- although that does make sense.

    I am using a 9V AC adapter with a 5V Vreg for the positive supply...

    I am running LED's but they are buffered from the PIC's outputs with BJT's.

    EDIT: putting the cap back solved the problem... argh! sometimes I feel so foolish =)
    Thanks guys..
