PIC microcontroller

[matt]

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:

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:

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,
