I need use a blf file for CAN simulink modelling. I couldnt read the blf.

Hi;

I am using R2021b academic use for Matlab. I wrote the codes that in below. I got error "Can't create a std::string from this data.". How can I fix it?

load canData.mat

canMsgTimetable = blfread("example.blf");

canMsgTimetable = canMsgTimetable{1};

startTime = seconds(canMsgTimetable.Time(1))

stopTime = seconds(canMsgTimetable.Time(end))

Ts = 0.01;

startTime = round(startTime, 2);

stopTime = round(stopTime, 2);

canFDMsgs = canFDMessageReplayBlockStruct(canFDMsgTimetable);

save DriveReplayFD.mat canFDMsgs

Maybe your filename or filepath contain the characters which are not included in ASCII.

I have met this problem when there are some chinese words in my filepath.

Any update on this topic? I've been facing the same issue using the blfread() function. I've tried to rename the file, probably it is not related to that.

Hi zozan,

This error occurs when you have special or non-ascii characters in your filename or filepath. Please rename the file name and path to only contain asciiString characters.
