Hi!
So, I bought a USB logic analyzer!
What I want to do is sniff the SPI connection between my Arduino Uno board and an FPGA board, but I'm (rather embarrassingly) having trouble finding a suitable way to hook up the test clips (I haven't done this before).
Any ideas on proper procedure for this would be helpful.
I am a bit tired so I'm not thinking straight right now 
Thanks a lot in advance!
Solder a short piece of copper wire to connect Your probe to.

I have found you can pull the jumper wire up out of the female header on the Arduino just far enough to clip the test clip onto the exposed pin and there is still enough pin length left to get a connection in the header.

Thanks, I will keep this is mind for future projects (when I've gather soldering equipment:)).

Thanks !
I have these wires as well. I don't like them because they don't attach as firmly as the others, but for this task they might serve a purpose, right?
Hi,
Why not just plug one end of a male to male jumper in where you want to take the signal from and use the analyzer lead clip to attach to the free end of the jumper?
