'[AVR][OT] Bargain price for AVR debugger'

This may interest some.

I found at DealExtreme an USB AVR JTAG programmer/debugger for $9.99
(shipping included).
Much cheaper than my AVR Dragon ($49.90 plus shipping)

<http://www.dealextreme.com/p/jy-mcu-avr-usb-emulator-debugger-programmer-jtag-ice-for-atmel-104374>

Much smaller than the Dragon and plugs directly to the USB port, no USB
cable needed.

They say it works seamlessly with AVRStudio.

Ordered one just to see if it works. When it arrives (in a month or two)
I will post the results here.


Best regards,

Isaac

And WILL NOT WORK with ANY newer chips. It's a OLD
Mk1 JTAG which you can build yourself.

It can only debug about half a dozen chip.

You are comparing apples with seashells.

Out of curiosity, how do you tell it is a Mk1 JTAG?

I can't tell for sure but it's a BIG gut feeling. Yes I have one of those.

They are not claiming compatibility one way or the other and
there is no list of supported devices on their website as far
as I can see. Non existent tech specs.

JTAG Mk1 design was\is readily available and it uses just a Mega163
or similar, JTAG Mk2 design has never been made public.

The only technical details given on that website is :
Working voltage: 3~5V

The Dragon will work with
Target Voltage Range 1.8 - 5.5 V

and JTAG Mk2
Target operating voltage range of 1.6V to 5.5V

Both of the above support JTAG, DW and some\all PDI
devices. No mention of the other interfaces with the
DealExtreme type.

I would really be interested to find out if I'm wrong
with this one so please post your experiences with it
when you get it.

If you take a close look at the silkscreen on the back side of the
board it says "JTAGICE VER1.2"

This woud be supported by the three high pin-count SMD chips on the board.

At $10 shipped, it's worth the gamble.  If it can program anything at
all it is worth $10.

Still, if anyone can confirm what this board is, what what software
supports it, that would be much appreciated.

If it is indeed the JTAG MK1 as I suspect you can use:

"Supported Devices

Currently the JTAGICE supports the following devices:

ATmega16(L),  ATmega162(L), ATmega169(L or V), ATmega32(L),
ATmega323(L), ATmega64(L), ATmega128(L)."

and I think one of the CAN chips.

It's all there in the Help files in AVR Studio version 4.xxx
I don't believe AS5 supports the old ICE but don't really know.

Since we are talking about it, I found one more:

<http://www.hobbyking.com/hobbyking/store/__21321__USBasp_AVR_Programming_Device_for_ATMEL_proccessors.html>

It is a different one and is even cheaper, US$4.75 plus postage. If one
is buying anything else from HobbyKing, then the final price is unbeatable.

I will buy mine together with my next order there.

Note that this is an ISP programmer only.  No JTAG, no debugging.
(I guess that theoretically it could support DebugWire, but that seems to be sufficiently undocumented that it isn't supported by any open source tools.)

Indeed, but for beginners with a low budget it may be a good option.
Also for electronics teachers that need several at the same time, they
are so cheap.
