'17C766 Programming'
2000\01\28@152854 by Sean Breheny

Hi all,

Someone here at Cornell asked me how to program a 17C766. Are these
compatible with the PICSTART Plus? I would think so (with the appropriate
surface-mount adaptor) but he says that he has tried that and is having
trouble. The mchip website isn't all that helpful.

Also, does the 17C766 support ICSP? I didn't think so, but the mchip web
page says that their ICSP adaptor for the promate II will work with all
PICmicro devices?!

Thanks,

Sean

Sean,
       The 17C766 does support ICSP. We have a board in development with this in
it. Even though we have put the wiring on board for ICSP we won't use it as
we are running in microprocessor mode.
       If you are looking at using this for a hobby project, you may want to see
if you can buy them in small quantity as we had to buy 117 (?) of them.

My PICSTART with 2.01 firmare supports the 17C766.

Walter,

Do you know if any PICSTARTs are being shipped with this firmware version?
I see that a file to update your PICSTART to this version is available on
mchip's site,but I am wondering if that needs to be done to ALL picstarts
or only older ones.

Thanks,

Sean

Hi Wendall,

First off, I am not using this. Someone who works with me here at Cornell
is using it in a research project, and he is new to PICs. He already has
some of them.

What ICSP protocol does it use, the same one as the 16F84 and the mid-range
PICs? It's funny, because I could have sworn that the 17C42 and the rest of
the 17Cxx and 17Cxxx series needed to be parallel programed, which was why
you couldn't use Tait-style programmers to program them, or can you?

Thanks,

Sean

Sean,

The 17C4X do not have ICSP. The 17C7XX do have it. The protocol is buried
somewhere in Microchip land, but the same ICSP module for the Promate will
work for it I believe, but I have not tried it yet.
The connections can be seen in the data sheet section 17.6. It does require
7 lines instead of the 5 that the 16 series use so the protocol is most
likely different. The data sheet describes it as a bootloader and looking at
the pin configuration, it uses the standard USART/SCI for reading the data
in synchronous fashion.

Yes, there are lots of people using my adapter chart to role their own
picstart plus adapter. http://www.new-elect.com/adapters.htm Use the
WARP-17 wiring.

Never is. ;-(

All the 17C75x and 76x devices have a ICSP mode that uses 7 wires (including
a oscillator). However the picstart plus does not support this mode, only the
25-wire parallel mode.

Recently the EPIC programmer was upgraded to program these parts via ICSP
but the software will cost but it could be used with most tait style
programmers if you add the oscillator and tie the test pin high I think.

The ICSP specs are on the mchip web site. They are included with the parallel
specs on the same document.

I upgraded from 1.2 to 1.5 and now 2.01.
Just burn a fresh 17C44 with the old version
and replace the processor.

I have a new spare PicStart and it came with
2.01 loaded.

So I guess 2.01 is the latest and greatest.

I get a 404 on that http://www.new-elect.com/adapters.htm page, Jim.

http://www.new-elect.com/adapter.htm works, though.  (No "S", singular
of adapter.)
