AVR-Chat

Hello all;

  I've tinkered with the 2313 and the pic chips for a
while. I'm looking for a good programer with
electonics experience for possable partnership.
Drop me a line if your interested.

Reid

On Saturday, I attended a Meet&Greet function for our local FreeCycle
organization (check out www.freecycle.org for mor einformation on a
wonderful movement).  There, I obtained an odd thing:  A USB based
"Smart Card Reader" (branded for Target Stores).  Included is a CD with
the drivers and so on for WinBlows.

   In any case, it occured to me when I saw it that this might prove a
useful toy to have.  Wondering if anyone here has interfaced such a
thing to an AVR?  I know Atmel makes SmartCard chips.  It may become the
basis for some sort of an interesting project, eh?

   Well, for free it seemed like a bargain too good to pass up (much to
my poor suffering wife's chagrin).

The AVR would have to be a USB host - and that protocol stack is very
complex/large

  Perhaps, but there are a few AVRs that support USB.  But then again,
what would be large and complex about USB?   Granted, the suppoort on a
host for USB could get comoplex, since it is supposed to correctly
idnetify and configure itself for whatever is plugged into it.

  But a USB peripheral is just a fancy serial communications device.
And most of that "fanciness" is in the hardware.

You can connect this board to your AVR and read any USB memory 
device and even a mouse or keyboard

Reid:

    I don't know about you, but I have unlimited free long distance
(VoIP phone through Road Runner).   How about you send me your phone
numebr, and we chat on the phone?  In the event that you also have fre
or low cost long distance, my voicenet address (*laugh*) is 402-261-4343

I have a AVR icecube from ecros tech which is a JTAG ice programmer. I
had to upgrade avr studio to 4.12 and the firmware upgrade is not
working so I can not debug with it. My program gathers some GPS data and
writes it to eeprom. I want to verify what it is. But since I can not
debug with AVR Studio I was looking for a way to read the eeprom. My new
PC (laptop) does not have a parallel port so I can not use the parallel
port with avrdude. I used to use the -t to look at this.  Is it possible
to use avrdude with the jtag ice? If so what is the programmer parameter
to use?


If not can I use avarice in a interactive mode to view the contents of
eeprom?

The newest version of AVRDUDE, version 5.0, supports the newer JTAGICE
MkII protocol, but we don't yet have support for the original JTAGICE
protocol.  The ECROS ICE Cube uses the original protocol, so it is not
yet supported by AVRDUDE.  We hope to have this support in a future
release.

If your laptop has a serial port, or you have a USB to RS232 adpater,
and you have access to another programmer type, like an Atmel AVRISP
($29 from Digikey) or even an STK500, you can use AVRDUDE to read out
the EEPROM.

It's generally good to have at least one other programmer type in your
toolbox for these "just in case" moments, at least as a backup.  I
personally have had to fall back to "plan B" on a few occasions -
means the difference between continuing to make progress and being
stuck.
