TMS570 DCAN User Guide

Other Parts Discussed in Thread: TMS570LS3137

I read one of the other post in this forum and someone referred to a DCAN User Guide. I'm using a TMS570LS3137, where would I find the guide that relates to this micro? I've done searches on the TI web site and drawn a blank.

Thanks

Andy

    Hello Andy,

    I understand your confusion on this reference. People often will refer to individual chapters as user guides for the specific IP during discussions. The Hercules group does not release individual userguides for each IP that is in the device. We include all of the IP user guides in our technical reference manual (TRM), spnu499b as chapters. The TRM is available on the product page for TMS570LS3137. You can either go directly to the product page to get it or you can search for the the document number, spnu499b.

    Hi Chuck,

    thanks for your answer.

    I must be going blind then. I have a copy of the TRM already, but I can't find the answer to my question. It's probably staring me in the face, but I can't see it.

    My question is a very basic one: How do I set the CAN Id (or DLC) for a transmit message?

    There doesn't appear to be a specific register for this and, if it has to go through the interface registers, I can't find a description of how this done, being as there are only two interface register and 64 message boxes.

    Sorry, ignore my last post. I was going blind! I've found it and I'm up and running now.

    Merry Christmas
