Hi All,

     Does anyone here know a really good static control method that works
     with the PIC16F84? I have six I/O lines that go outside of the
     project's case and go through really long wires to switches. Some of
     the wires are exposed and will be fiddled with by people, and I don't
     want the chip damaged. I've checked the Microchip application notes,
     and they say to put at 10000 pf capacitor from power to ground. Is
     this all that is necessary?

     I thought of putting in a TTL buffer or an optoisolator, but the data
     lines need to bidirectional. I also need to keep the costs down as
     much as possible, as well as the part count.

     Thanks in advance,

     Eric
