I think I am getting useful data now... I guess when it just returns 2 samples i need to reset everything cuz it goes buggy for some reason and will always return 2 samples with all channels low :(
It seems like i can usually get one good read with RLE enabled, then after that i get this 2 sample return nonsense where all the channels are low :(
So for my first adventure with my new logic analyzer is to play with our printers 1-wire connection to its toner cart :P
Now my understanding is that the pwr/io line is constantly high as long as the printer is powered up, and drops low when communicating back and forth. When I open the top of the printer (say to remove the toner cart) it will power that line off and reconnect it once I close the top...
So I figured for that I would set a trigger for when my channel-0 goes high (when i close the top), then a second trigger for when the line goes low.....
Problem is I don't think Im getting anything useful with the settings i have..
I am unsure on which bus mode this thing is using: ether standard (at iirc 15kbps) or overdrive (at 125kbps) So im guessing for standard I would use a sample rate of 20mhz and overdrive would be 200mhz?
(I also keep running into a problem where i get back just two samples -_-, is there a way to force the max samples no matter what?)
I have a need for a decent inexpensive analyzer (I thought the bus pirate i had would be suitable, but yeah not quite)
The max 32 inputs the OBLS has is probably overkill, but might be useful later down the road. My main immediate need is a continuous feed which i keep seeing that both the BP and this OBLS should be able to do, I just can't find out how to do that on my BP
If I get an OBLS, which client do I use to get a live/continuous feed of the logic? (well probably don't need the live/continuous feed since it has a bigger buffer than the BP but still would like to have that option)
