Looking for a CAN Emulator

Do you want to drive messages onto a bus or actually try and bit bang onto the bus?

I've done a box that talks CAN between them. The product uses a LPC1769 and a TJA1054 driver chip

I wrote some code that would capture the CAN traffic, shove it in a UDP packet and spit it out the Enet port. Another chunk of code on a linux box captures and does a app specific decode of the traffic.

Microchip has a CAN bus snooper thing that talks USB to a PC.

Not cheap, I think it was about $100USD. You can monitor and send traffic. Back when I was using mine the send side was kind of a pain. No scripting or such where you can build traffic streams.
