Interfacing Stellaris Launchpad to CAN bus

[Thomas1426459898 0]

Hi,

 

I've played around with the CAN module of the Stellaris controller on the Launchpad. To connect the Stellaris Launchpad to a CAN bus, an external CAN transceiver is needed... but only a few wires are necessary. See the attached circuit diagram.
