Well, I think the disk which came with the board had a number of demo source
programs on it. The rest including the latest IDE can probably be obtained
from Microchip. I can 'upload the contents' of the disk to the FRF.net site,
before I disassemble the website. Can also send it your preference.

Yes it is interesting to think about. Also projects which may be developed
in 'building blocks' in the HPSDR project, and proved, could be re-combined
on a stand alone board in the future. There is NO question that being
dependent on sound cards and windows drivers is a bummer!

Thanks

Eric

Eric,

Is there more on the disk than at
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE
<http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406
&dDocName=en021940&part=DM163025>
&nodeId=1406&dDocName=en021940&part=DM163025. I've pulled all that down but
not looked at it too much. I think the MCHPFSUSB_Setup had the driver in it.
Anyway, send the disk to be covered.

I've just started reading the PIC-a-Star articles and was interested to see
that the DSPx board in my Antenna Analyst, which doesn't do much when it's
analyzing antennae, has been used in at least some PIC-a-Stars, and that PIC
devices are used in several places. There may be limits on the total
bandwidth allowed with the PIC USB interface - it's only Full Speed 12Mb/s
after all - but it might make a Kittyheart board, a "cheap" version of an
Atlas USB interface board that could handle a 48Ksmpl/s Janus-like board and
a K1EL WinKey keyer. It's interesting to think about anyway.

Sorry for the late reply. I have all the software for the Picdem board and
will have to get it for you, I forgot to ship the disk. I don't think it is
available on the website.

Hmmm..

Anything can "Ride the Atlas Rails!"

Methinks there are MANY more PIC programmers than FPGA programmers, although
hardware is in a different category entirely. The PIC 4550 has USB
'built-in'. If one considers what Beppe and Wood Box Radio, as well as Peter
- G3XJP designing the Pic-A-Star did with a PIC what about the HPSDR project
add-in's! 

Just 'food for thought' with someone much more capable than me driving the
program. The project boards, and compiler were a no-strings offer. You have
no obligation to do anything with it! 

One of Phil_H's (and me and Steve - K5FR's) complaints was that we couldn't
compile for the 4550 with the FED complier, without errors, generated by
bugs in the compiler. Enough to make a grown man cry! Especially when the
weight Phil was carrying kept falling on his toes!

I still learned a lot over Phil's frustration, and at my age 'learning
something new' translates to FUN! I have a stack of 'spec sheets' in the
'reading room' (As well as QST's and now RadCom!)

Have fun!

Eric

Eric,

BTW, I've got the PIC USB board to blink its LEDs - the two of them in
alteration which seems to mean the driver connected ok. I've also reached
the part of the PIC Data Sheet about the USB module. Did you have something
in particular for a PIC USB Atlas-based board?

You grow tomaters out there in 6 land? Congrats! You have the only post for
today (so far!) on HPSDR!  

I won't tolerate NO posts to this forum every 24 hours. So Lurkers and
developers, and soon to be users. Tune in and Type. ANYTHING! 

Horst, you goin'to Friedrichshafen? (I'm still trying to talk my wife N4RVU
into it!) Have reservations! Eyeballs are the best!

Eric
