Hello to all,

I got the same error on.

I fixed it moving binlog.dll in the same folder of CanLoad (previously was inside folder x64).

After following your steps I called

temp = CanLoad()

and selected my test.BLF file to read in. As a result I get

temp = 
      sw: [1x1 struct]

where temp contains only software version, but no data.

Can anyone tell me whats going wrong?

Please have a look into the mFile of CanLoad. There you can find examples how to you use this tool. Further i found out, that you have put all corresponding DBC files into the same directory of CanLoad.

CAN FD would not supported, the mex file crashes.

This tool also works with asc files in the same way as blf files. but it takes much much longer.

Dear Tejas,

I have been trying to extract the .dbc files with the steps you have described, however, I am unsuccessful. I guess i'm just doing something wrong.

When I feed my files to the dbcModuleBatch.p, I get the following error:

>> dbc2ModuleBatch('Ehorizon__M002.blf')
Error using dbc2ModuleBatch
Too many output arguments.

I have also tried to feed the files to the CanLoad.m, but it have also failed:

>> CanLoad('Ehorizon__M002.blf')
Error using cd
Cannot CD to /Users/mac/Documents/.../CanLoad\ (Name is nonexistent or not a directory).
Error in CanLoad

I would really appreciate your help

Apparently, MATLAB has not developed the toolbox for the Mac OS...

Pay attention to Step3:

Unzip the folder contents
Put all the files that I have attached here in a folder.
Run dbc2ModuleBatch.p by click your right button of mouse to select the directory where including .dbc files, this step would build these four files named as can_module_ext.m, GetAsciiMessageFilterList.m, identify_DBC_Name.m, module_dbcname.m.
Place all the above newly files in the directory that contains the .blf files and add to the Matlab path.
Run CanLoad.p, this requires an input that is full name and path of the file.

Notice! CanLoad can not support CANFD!
