    Dear Friends,
    I'm a student, and I have to write a SW to connect an ATMEL CPU + CAN
    INTERFACE to a CATERPILLAR CPU via CAN-BUS.
    The protocol is SAE J1939.
    My problem is I don't find anything on the WEB about the specifications.
    Can anybody help me?
    Thank you in advance.

    * Find the SAE web site and see what it'll take to get the
    specification. You may be able to chisel it out of SAE for free because
    you're a student, or get your school library (if its a University) to
    buy it for you.

    * Get a copy of "Controller Area Network, Basics, Protocols, Chips and
    Applications" by Konrad Etschberger", IXXAT Press, 2001. The ISBN is
    3-00-007376-0. This is an excellent book, and I'd recommend it to
    anyone who's contemplating a CAN project.

    After you do that, you'll still need to know the messages that CAT uses
    -- that's up to you.

    Specifications of this sort usually have to be *purchased* directly
    from SAE, and they're *not* cheap :-(

    I love to cook with wine. Sometimes I even put it in the food.

    Try http://www.kvaser.com/ and follow the education link to white papers
    for this paper.

    Diesel Engine Control, CAN Kingdom and J1939

    That should give you a starting point.
