Looks like you figured it out, the dangerous prototypes site is the place to go. One thing to check is the firmware revision, the stock firmware seems to have issues in particular with run length encoding (one of most useful features on this guy), see I think the one on the portal linked at the info portal is slightly outdated and there is a 3.07 out there, although I think 3.06 works fine. My logic sniffer (ordered from dangerousprototypes last month) came with an older version, and an update fixed a lot of things.

Enjoy!
Ooooo ill check all the firmware and stuff then, TY. i really needed this device since the commercial ones cost 800 USD, and this was like 97 USD w/shipping. and the spi/i2c is what im trying to code now.

The spi/i2c decoder functionality is amazingly useful on this guy, although don't trust its decoded values as god given. I have not 100% figured out what the bug is (if I ever do I will try and file a bug report), but I have found odd behavior in the decoder if you try and decode a signal which has recently been acquired, as opposed to one which has been saved and reloaded (using the save/open commands under file). If you see it doing odd things try opening another sump instance and load the capture, that always seemed to fix it for me.
Also a heads up, for others who might want to get one, you can get them a bit cheaper from seed studio although they have a tendency to be sold out when I want to buy stuff from them

I was going to get mine from seeed in china, but couldnt wait for the boat-ride shipping. Our semester may be over before i get the programing done as it is.
is it possible to reassign the channel colors to match the wire colors?

I haven't been able to get the colors to match up (it is odd that the display does not follow the normal color code black=0, brown=1, red=2, the wires do...), you can make the labels on the edge read correctly which is what I have been doing.
One discovery I made was for the I2C/SPI/etc analysis, if you add marker1 and marker2, it will only analyze the data between them. not having either of them on the display seems to give erratic behavior. Made my life a lot easier!
