'[PIC]:Exactly what does a dsPICDEM board do???'

Continuing to work with  the ICD2 (I have to say that so far I vastly
prefer the Wisp628, but since I want to work with the ds3013 chips it
appears that the ICD2 is required), I have come to the point where the
documentation strongly suggests that I should get myself a dsPICDEM
28-pin starter demo board.  I looked up the price, and the little bugger
is fairly expensive (the ICD2 pretty much depleted the budget).  But if
I really need one, I can skip the prescription drugs for a couple of
months, I suppose, and get one.  Except that it is not clear just what
it does.  I have a perfectly good solderless breadboard that I have used
in the past (with the 18F452 and the Wisp628) for developing circuits.  
What extra does the dsPICDEM give that is crucial?  (I'm not criticizing
it -- just cannot figure out why it is necessary).

Thanks,
John

Doesn't
EasyISP give PIC10 and dsPIC support to
the Wisp628 hardware ?

Or
maybe it was just the PIC10s...

Another very interesting question is
when we will
see the next version of the Wisp628 firmware, and
what
devices will be supported in it...

Hm... that didn't looked good when I got
it back
from the listserver.

Sorry Wouter, it was not ment to be "picky".

I
should have added a few smileys there...

Or left it out...

Damn...

Just PIC10Fs. I really need to get around to running WinMerge over the "base"
version of the code I used to make EasyISP and the new EasyProg firmware.. I
think it's time I added a few more chips to the support list..

No ETA yet - it's a spare time project, so it's quite low on the to-do list
(right after "stuff that I get paid to do" and "stuff I really should finish
off someday"). I've got an ICD2, so I don't really use the Wisp628s much
anymore (I've got two - one homebrew, one built from the voti.nl kit). The
homebrew one runs EasyISP, the voti.nl one runs the standard Wisp628
firmware.

Later.

no offence at all.

but could you arrange for a few more hours, or better days! in a week?

It is glad to know that you are planning to add more chips to the
EasyISP. I understand that it takes time.

Just one more thing, I heard that EasyProg itself does support
the dsPICs. Someone is working on it but I have not heard from
him for quite sometime.

Another possibility to use a bootloader. Since the OP has access
to an ICD2, it would be okay in this case. One of the fellow
PIClist member has written a bootloader for 30F4011. Maybe I can
persuade him to publish the bootloader even though we think that
the host application VB codes need to be polished. I was trying to
port his bootloader to 30F2010 but I decided to learn USB stuff
first. PIC FS USB is also much more worth the money than dsPICDEM
28-pin starter demo board. Anyway it is still in my plan.

As for the dsPICDEM 28-pin demo board, there is not much inside
and I think it is not that difficult to build on a prototype
board. Actually I think it can be finished in one day. Of
course one needs to get the samples of dsPICs ready first
and the RS232 interface IC (can be replaced by MAX232).

Regards,
Xiaofan

My version definitely does not support dsPICs.  Someone here had expressed
interest in adding dsPIC capability.  I gave them some additional source
code and promised a ProProg when done, but I haven't heard anything in a
while.  The dsPIC programming algorithm is not trivial.

This discussion got kind of off track, and I never did get much of an
answer to the original question.  :-)  However, from the responses that
I did get, plus downloading some documentation from Microchip and
studying it, it now seems pretty clear what the dsPICDEM 28-pin demo
board is all about.  I could build something to do what it does
(although not in a day!) but am not sure that it would wind up being any
cheaper.  So I will go ahead and order it from Microchip.  One of the
problems that I always have on these projects is getting side-tracked
onto interesting projects and getting away from the original goal.  So
I'm trying to correct that character deficiency by keeping my eye on the
ball, my shoulder to the wheel, and my nose to the grindstone (it will
be interesting to see if I can get any work actually done while in that
position. :-)
