My recollection is that the other list was formed to keep the S/N ratio of this
list up.

I would say go with the flow. If the discussion is happening here and "not
there",
keep it here for now. When the project has gained momentum you can always decide
to go off-list again.
The analog I/O ranges from "too easy" to "trick
Yes, it's still active. I've created a mailing list and google group
just for the counter project. opencoun...@googlegroups.com to keep the
counter project from going out to all 800 time-nuts.

I looked over the Digilent site again, and I have to agree. There is a lot
of information available, and the textbooks available look interesting as
well. If I get really turned on, I may buy a board and book.

On that note, does anyone know if this counter project is still active? Some
time ago I asked about this, but never got a reply. Maybe the e-mail got
eaten by a spam filter, or maybe I just didn't ask nice enough, I don't
know. ;->
If there is still an active project, I'd be interested. If not, I
I'd like to second John's suggestion to go with the Nexys2. As far as I'm
concerned it has pretty good value for money.
Regarding the standalone use, it has a configuration prom that you can use.
That way it will automatically load your design on powerup, without needing
a programmer every time.
They look interesting, Tristan. Gee, nobody's "in charge" of this, I'm not
sure it's even a project at this point, and AFIK there's no out of turn
:-). I too like the Arduino, in fact I've settled on them or the Propeller
for projects if I can, so the boards you propose may work just fine.

Hi Don,
At the risk of speaking out of turn, and not knowing too much about this
project (I'm new here!) have you considered something like these boards:

They use the Spartan 3E chips, like alot

Seems right, John. For just a little more, the other units you recommended
might be better. Still a lot of programming work to do, but implementing a
simple counter/period measurement might not be too bad. I've never
programmed an FPGA, so have no idea of the practicalities of really
accomplishing

I think that's what it was called, yes. There was a console version and a
GUI version, both closed-source. Hopefully they also provide a linkable
library by now; that's what you'd want to ask about.

Would that be FPGAconf? It's still mentioned in the documentation and
seems to be a kind of bitfile loader. There's no mention of a requirement
to use it, but it may be necessary. Docs mention Altera or Xilinx packages
and a c++ compiler as necessary.
I just skimmed the document.
