    thank you for any help
  2. Go to, and consult the datasheets for that
    processor. It appears that pin 16 is an I/O pin - bit 6 of port B -
    if that is so, then it gives an alarm because the program makes it
    give an alarm for some reason - you'd have to ask the person who wrote
    the program for more information.

    Why do the hopeless jerks almost always post using Google ?

    Dear Yar,

    I suggest you 'get a clue' by reading the data sheet and learning
    something about how electronics works.
