'PIC newcomer; advice?'

Hi...

I just subscribed to the list minutes ago.  I'm into
robotics and electronics and have tinkered a little
with the Z80 microprocessor and studied the 68HC11
(never used it, though).  It's time for me to learn
something about PICs, as I have some projects that
ought to be perfect for them.

I'd love to get an overview of the different families
so I can choose a direction to get started in.  I've
been seeing the 16C84 mentioned quite a bit as a great
way to get started.

I want plenty of I/O, memory, and I think using EEPROM
or flash would be least annoying to do development on.
Is the 16C84 right for me, or are there others (more
memory, perhaps) that would be better suited to my wants?

I've glanced at the PIC FAQ and realize that there is
just too much info out there for me to sift through,
which is why I'm here asking for advice.

I'd love to get enough info that I can make my first
purchase of programmer and chips this coming Saturday.

Thanks in advance for any info!  :)

-Chris

Welcome.  Remember how to unsubscribe though.  ;-)

Yes, but it is superceded by 16F84.  Go to Microchip's web site, on
http://www.microchip.com/ and download the data sheet.  It's in PDF
format, which is a pity, but is readable with the right proprietary
software.

The data sheets have all the instruction set as well, which is good.
I printed mine out.  I asked for a CD but the local agent has not
responded.

The 16F84 sounds right up your alley.  You can always slave another chip
to the first if you really need more I/O for small projects.

I recommend the Dontronics http://www.dontronics.com/ programmer for a
first go.  DT-001K is what I bought, and it has worked well for 16F84's.

For smaller projects, consider the 12C508/12C509.  They are mere eight
pin DIP's with six I/O and internal oscillator options.  Still
programmable the same way, virtually.

Check out these sites for info and application notes..
http://www.questlink.com/page.htm
http://www.microchip.com/

The 16C84 or 16F84 is flash/e2 but does not give the functionality of the
bigger chips or the amount of rom and ram. You can do some devoplement on
the flash chips then move it to the bigger ones for the application. For io,
rom, ram and built in functions look at the 16C72 to 77 series chips. They
are eprom though.

Hope this helps.

Where do you come from Chris? I'm an FAE for a distributor of microchip and
might be able to get you some data or point to somewhere that may be able
to help.
