Accessing M-file S-Function parameters inside TLC file

Hi,

I am writing a TLC file for a M-File S-Function in order to generate C-Code but I am wondering how I can access the S-Function parameters inside the TLC file.

Inside the M-File S-Function's setup(block) method I have the following:

 block.NumDialogPrms = 2;
 block.DialogPrmsTunable = {'Tuneable', 'Tuneable'};

which seems to work since I can access and validate the parameters also in the CheckParameters(block) function.

However, inside the TLC file's BlockInstanceSetup(block, system) function the following lines do not work:

 %assign port = LibBlockParameter(P1, "", "", 0)
 %assign pins = LibBlockParameter(P2, "", "", 0)

and I am wondering why.

Best regards,

Arne

Do you call "block.AutoRegRuntimePrms({'P1','P2'});" in DoPostPropSetup? If you call block.AutoRegRuntimePrms without the parameter names, I think the default names used are MSFcnParameter, MSFcnParameter1, etc.

Thanks for your answer.

I fact I did not call AutoRegRuntimePrms. Now the parameters are available. Thanks!

Can I access nontuneable parameters in a similar way?

To answer my own question: WriteRTWParam() to be called in the WriteRTW callback seems to be the way to go for nontuneable parameters.

Glad you found the answer. FYI, you can type "sldemo_msfcn_frame" at the MATLAB prompt to see an example for WriteRTWParam().
