Free CAN Emulator (req)

The least expensive would probably be a dev board with CAN peripheral, something like this: also available from Note: I haven't used this particular board but I do use other Olimex dev boards and STM32F Cortex-M chips, so I'd presume that it would work okay. It appears that it uses the open source Maple environment, so your compiler setup should be cheap and (relatively) easy.

I use a PEAK CAN/USB

also available from for general sniffing and poking at CAN busses. Not free but reliable and comes with DLLs and Linux drivers to integrate with your own code.

ome temeetry using a Cellular GSM module, but i need first debug my CAN int erptreter.

Thanks, i will give to it a try !!!

You might also have a look at our ELM329 integrated circuit. Although you would need to build it into a circuit to use it, the interface is a very simple one - serial based with ascii characters. See
