One of these cables came with my AVR Pocket Programmer, but was defective. After a month of trying to figure out why I kept getting the “initialization failed, rc=-1” error, I jammed a few 2-row male headers into the cable and went to town with a continuity tester. Sure enough, the MOSI on the 6-pin plug was open. I stuck a few male-male jumpers between the 10-pin plug and my target AVR and bingo-presto, it worked perfectly.

So, for anyone who gets the rc=-1 error, and has “Power” “D-” and “Stat1” lit up, try replacing the cable first! I hope this helps someone out there. Now I’m off to find some ribbon cable-making doohickeys…

For anyone else wondering, I took some photos of the connector: isp connector on uno

Nevermind-I found it: whichever way the green power LED comes on. Hah!

I am at Starbucks and don’t have a multimeter with me. Which way does the 6-pin connector go on an UNO?

This cable works well with the AVR Dragon and Olimex proto boards – it can do both JTAG and ISP mode.

I found a nice one at tinkerlog.

Just remember to mirror it, since you’re dealing with the cable, not the header.

Could we get the schematic for this cable posted?

okay, after trying to make my own cables I switched gears and bought some premade ones from the microcontrolershop. I use ann AVR dragon and they sell 6-pin 6-pin that work for all arduino and many avr dev boards.

for what it’s worth, I just bought some 2x3 female headers and the crimp pins you jam into them from digikey and made 6 pin, 2x3, female-female programing cable with my usual 22 gauge hookup cable.
Still can’t figure out what everyone else with an AVR dragon is doing to program with the ISP.

I wish I read blink4jona’s comment before buying as what I received is not what I expected. The cable can connect ISP 10-pin to 10-pin, 10-pin to 6-pin, but not 6-pin to 6-pin (there is only a single 6-pin connector).
The description is misleading as it suggests both 10-pin and 6-pin ISP interfaces are supported. Also you can not tell from the picture that only a single 6-pin connector is included.
Although it may be useful to some, we need a no fuzz 6-pin to 6-pin alternative.

is there a reason SF doesn’t sell a 6 pin to 6 pin cable? I want to connect an AVR dragon to various micros, all of which have the 2x3 header, and I can’t find a 6-6 pin cable. I am new to this so maybe I am missing something obvious. I know the JTAG connection requires 10 (2x5) pins, but most of 8 bit AVRs can’t be programmed by JTAG, right?
Right now I am using this together with the AVR programming adaptor, just seems like kind of a kludge.
