I see all these can bus shields people are using and I wondered if you can hook the can bus from a car directly to the Arduino Due or any other Arduino without a CAN Transceiver?

Don't the shields usually have 2 chips - the transceiver, and the driver?
Microchip MCP2515 CAN controller and MCP2551 high-speed CAN transceiver.

Yes but i figured there had to be a way to do it programmaticly.

Look in the DUE section of the Forum.

Tom..... :slight_smile:

With the DUE, you just need the CAN bus driver module.
You can (err, pun) buy them on eBay for few dollars.


Yeah I I was just curious if it could be without extra hardware. But I guess not. Thanks guys.
