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

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
