Ask for support extended CAN format about dwCANInterpreter_buildFromDBC function

Dear Support,

I works as research engineer at Hyundai Automotive company Commercial Vehicle Advanced Electronics
Development Team.

I am developing a project using Drive PX2 Autochauffeur.

When I try CAN communication and try to use ‘dwCANInterpreter_buildFromDBC’ in DriveWorks API, I have a problem.

It said ‘4. ignores messages with CAN Identifier larger than 2047 (does not support extended CAN format)’, but we have to use extended CAN format because commercial vehicle communication follows SAE J1939.

As soon as possible, I ask for support extended CAN format about dwCANInterpreter_buildFromDBC function, please.

Thanks in advance

Dear tiger0219,

Can I know you’re using DPX2 SDK version?
If not 5.0.5.0a, could you pleas update DPX2 SDK to the latest version?
Because we had fixed extended CAN issue in 5.0.5.0a. Please see Linux Release Notes. Thanks.

I use the 5.0.5.0a version that the latest version.
But When I saw the Driveworks SDK Reference 0.6.54 Release, it can not support extended can format in ‘dwCANInterpreter_buildFromDBC’ function.

I refer to Driveworks SDK Reference 0.6.54 Release (below flow)


DriveWorks SDK Reference -> DriveWroks API -> Sensors -> CAN -> Interpreter -> dwCANInterpreter_buildFromCallbacks


It Notes " 4.ignores messages with CAN Identifier larger than 2047 (does not support extended CAN format).".

please check this Note.

Thanks
