Other Parts Discussed in Thread: EK-LM3S8962, SN65HVD251

hi, im new to this stellaris launchpad...

i bought it because it's price and because i red that it has CAN port...

does anyone use the Stellaris Launchpad to comunicate over CAN BUS? 

 i guess there are some examples on the software but i don't know if i need external hardware (transeiver for the CAN protocol) or the Stellaris Launchpad it's ready for CAN... thanks

    So "help" was the best summary you could think of to clearly & accurately describe your post??

    Are you familiar with Stellaris on any other platform?

    Are you familiar with microcontrollers and/or (digital) electronics in general?

    Are you familiar with CAN communication in general?

    Have you looked at the schematics and studied the User Guide?

    Jose,

    If you post a better description of your question in the topic title, it lets other people investigate and respond to a post that falls in their area of expertise.

    The Launchpad does not have a CAN transceiver on the board. If you want a Stellaris evaluation kit with a on-board transceiver, I recommend the EK-LM3S8962.

    If you want to add a CAN transceiver to the Launchpad, I recommend the SN65HVD251. You may be able to get free samples of the breadboard friendly DIP package version.

    No, it was a very poor description because it gave no idea whasoever about what help you want!

    Just about every thread on these forums is started because people want "help" of some sort - Imagine if all the threads were just titled, "help"...

    Help!

    Earlier suggestion of 8 pin DIP Can xcvr is just what our group did - you'll need two - one for each end...
