    I just purchased a PIC microcontroller. I've used an eval board for the
    motorola HC11 and it had a serial port built it. How do i connect a PIC uC
    to the computer to upload code?

    Thanks!

    There are a hundred different models of PIC controllers.

    Many of those can be programmed with inexpensive programmers
    available on Ebay that will connect to your serial port or
    sometimes to your usb port. Search Ebay for pic programmer
    to get some idea of the variety available. Often you can get
    one of these for under $20.

    Which one?
    It also has code to load applications too. It's called a bootloader.
    A raw PIC requires a programmer. Here is a PICLIST page that lists a
    bunch of them:

    http://www.piclist.com/techref/microchip/devprogs.htm

    I have a programmer of my own design that can be used to dump code in a
    pinch. You can find the Trivial Programmer here:

    Since you are used to bootloaders, I would suggest that you continue down
    that path with your PIC. You can find out a lot about PIC bootloaders on
    the Tiny bootloader page:

    http://www.etc.ugal.ro/cchiculita/software/picbootloader.htm

    Be very aware of the fact that you still need a traditional PIC programmer
    to get the bootloader code into the PIC. It's one of the primary purposes
    of my Trivial Programmer series.

    Good luck with your PIC stuff. You may want to subscribe to the PICList. There
    are well over 2000 PIC enthusiasts there that will be happy to answer
    questions that you may have. The PICList site is a virtual encyclopeadia
    of PIC information.

    Hope this helps,

    BAJ
