Get Parameter Value from Masked Block in TLC code

Hello all,

I want to get a "setPort" variable from a masked "MyFunction" block by using LibBlockParameter function, but it did not work.

This is my code :

%assign u = LibBlockParameter(block.Identifier.MyFunction, "", "", 0)
%<block.RTWdata.port> = %u;

Please give me some advices. Thanks so much !

Is this TLC for an S-function block? How do you register the parameter in the S-function?

Hi, This is TLC for an S-Function block. I create the mask to input the value for the parameter, so i want to get this value in TLC code.

Please help me, Thanks !

Ngo: Please also specify how you register the parameter in the S-function code (you need to do this in addition to creating a Mask parameter). That is key to answering your question.

Hi,

I create a parameter through Mask Editor. Then i use S-Function Builder to generate the TLC code and modify the Outputs function of this file.

This is my code :

%assign u = LibBlockParameter(block.Identifier.MyFunction, "", "", 0)

%<block.RTWdata.port> = %u;

Please give me some advices. Thanks !

Hello,

I am facing the same problem i have created popup parameters and i want tlc to read the selected value or number and then pass it to c code.

Best regards,

Hallo,

I have also same problem.

Please attach sample files that demonstrate your problem. There should be a Simulink model file SLX, a C or C++ file for the S-Function, and attach the TLC file for how to code generate the S-Function. Attach any output that you get when you are trying to code generate this model.

See the documentation on ssSetNumRunTimeParams, you probably need to be calling that in the S-Function C/C++ code. See documentation on ssSetNumSFcnParams.

See documentation on ssWriteRTWParameters and the mdlRTW function for writing parameter values given to the S-Function MEX out to the model RTW file during code generation.
