Pic16c621

Archiver

I would like to start programing the pic16 series, I
have knowledge about the HC11 microcontroller and the
Basic Stamp.

Who can tell me how can I program a pic,, if I need a
special board or if there is any squematic of a
programming board so I can build it.


Thank you very much
Alex

Head over to <www.piclist.com> and follow the instructions to sign up to
the piclist. Also check out the code snippets and links - they will help
you get started quickly.

The 'f84 isn't quite as easy, but the PICs that can use low voltage
programming--such as PIC16F873, '876, '877--are easily programmed
directly with a Stamp. By that I mean the Stamp has all the smarts
needed to control the necessary timing and logic levels/edges. The
other PIC models need just a bit more hardware to control a higher
voltage level.

The only real challenge is presenting a hex file (the output of a
compiler/assembler, the input to a programmer) to your Stamp for its
further use. A small PIC program can be directly embedded in DATA
statements with the aid of a text editor and some patience. A
larger one requires contolled transfers from a PC.

I've been working on and off with this for a few months with good
results. I've been using Microchip's (free) MPASM assembler to
generate hex files, then a DOS program to read and download the hex
files to a Stamp which then programs the PIC. Gotta be the world's
cheapest way to play around with PICs if you already own a Stamp.
Or, if you don't have a Stamp, buying one is a relatively cheap way
to be the proud owner of an intelligent PIC programmer.

Have had further great fun and premature hair loss developing a
Stamp+PC system to run and control the '876/'877 on chip debugger
subsequent to programming. IMHO, the OCD is one slick capability on
these selected PIC models. Microchip wants a bit of cash for their
OCD development system--if you have a Stamp and a PC, you've already
spent all the money needed.

Microchip's programming specifications spell it all out for your PIC
of choice if you want to try this yourself. When I get the bugs out,
I'll be making my solution freely available.

Steve

The http://www.piclist.com site already mentioned is a great resource.
Also Square One has a series of books that are good for beginners with
the PIC series. http://www.sq-1.com

I was wondering a while back if you could easily build a 16f84 programmer
out of a stamp...
