Logging data with TI F28379D C2000 development board in Simulink

Hey All,

For a motor control project I want to save my scope data to the workspace or a file(the Simulink model is in the attachment). On other hardware this worked fine in the Simulation Data Inspector. However when I select the signal I want to save nothing shows up in the data inspector.

As a workaround I tried using the save to workspace block and the save option in the scope. However I was only manage to save the last 8 samples.

Is there someone that has used the F28379D for logging signals succefully? If so please let me know, then I now it is possible at least.

Also it will be greatly appreciated if someone has a working model and wants to share that with me.

Any other suggestions are also welcome.

Thanks,

Dirk

Hi,

Please use the below script to stitch the files to one MAT file.

varName = 'ScopeData2';

list = dir(fullfile('C:/yyy/mat/', '*.mat')); %Path to MAT files..

name = {list.name};

str = sprintf('%s#', name{:});

num = sscanf(str, 'Data_%d.mat#'); %IMPORTANT: provide name of the mat files here

[dummy, index] = sort(num);

name = name(index)';

time = [];

data = [];

for i=1:length(name)

eval(['load C:/yyy/mat/' name{i}])

time = [time;eval([varName '.time'])]; %#ok<AGROW>

data = [data;eval([varName '.signals.values'])]; %#ok<AGROW>

end

finaldata = [time,double(data)]; % Sort with respect to time

sortedfinaldata = sortrows(finaldata,1);

HTH,

Thanks, I will try this.

Edit: It works.

Do you know why the simulation data inspector doesn't work with this hardware?

Hi,

Please try 'Data Logging' section at below link:

Thanks for your response, this works indeed.

But it results in thousands of files that I need to put together later. Is anyone aware of an option to write it to a single file or to the simulation data inspector?

Kind regards,

Dirk
