Open Bench Logic Sniffer / Sniffing CAN signals?
I have a desire to analyze a CAN bus.   I was looking at the demo software for the Intronix LogicPort.   They have a CAN interpreter that they use connected to the CANL line.  From what I have found that will give you about 2.5v on the idle bus and about 1.1v for a dominate bit.  It looks like they use a logic threshold of 1.6v (which is adjustable on the LogicPort) in order to analyze the bus.  I have looked at the datasheets for the buffer and FPGA and am having a hard time getting a feeling for how this work work. 


Any idea if this would work with the OLS?  Is there a threshold that I could get with just a voltage divider?  Any input or ideas would be appreciated.

Open Bench Logic Sniffer / Next batch of OLS's?
Just curious if anyone has any info on when Seeed might be getting the next batch out the door.  When I ordered they were showing an inventory of -81 units.

Thanks
