CANalyzer / CAN Inspector

Postby 01-0041 on Sat Dec 28, 2019 3:26 am

Okay,

I am going to ask for help on this one…

Looking at the attached image pulled from CANalyzer how would one decipher the last pair (04) to use in a C1XX template?

I have tried various combinations and must be overlooking the obvious!

Thank you!

Does that information appear for every instance of the CAN ID XXX? (ie, are you sure it's not a compound messages?)

Last byte of data in that packet, would be selected by using offset= 7, length = 1. BitMask = FF

If you wanted to retrieve the value of 4, then the Multiplier = 1, Divisor = 1, Adder = 0

David,

Thank you!

Yes it does appear for every instance... It's a switch - should be easy right?

Unfortunately using your suggestion didn't work either. Who knows maybe it's a compound message?

I'm going to make some guesses here.

Any chance the CAN ID is incorrect? The C12x dashes specify the base address in hexidecimal.

Or the Address format is 11 bit (standard), and you've checked the "Extended" format (29 bit), or vice versa.

Are you receiving other information from this CAN ID (CAN Address), or is this the first time? (i.e. Could there be something incorrect in the CAN template, like the "Device:" parameter -- I would expect "Receive Message").

Are you sure you're using the correct CAN bus for your Comms Template? I think CAN Inspector might use CAN 0 / CAN 1, but the Dash Manager uses CAN 1 / CAN 2.

Have you specified Diagnostic Channel? If so, what is the value of that when it should be receiving data? (Use Online -> Monitor Channels)

Hi David,

I was working on the wrong CAN ID - difference of a 5 vs an F.

Once I corrected my issue it worked just fine. I should have posted a follow up!

Thank you for your continued support!!!!
