Embedded Coder: How can I configure a Simulink model to generate model parameters as regular (non-static) C++ class members?

Using Embedded Coder, I would like to generate C++ code from my Simulink model and then use multiple instances of the C++ class in my custom C++ code.

How can I prevent model parameters from being generated with the static keyword, so that multiple instances of the generated model class can be used?

I tried different Model settings, StorageClasses and Code Mapping, but the code for the model parameters is always generated as "static":

// Tunable parameters

static P_signalGen_T signalGen_P;

Hi Wojciech,

You can follow the instructions mentioned in the following MATLAB answer to make the model parameters "non-static":

• Does Embedded Coder support instance-specific parameters for top model when generating C++ code? - MATLAB Answers - MATLAB Central

Hope this helps!

Hi,

I tried the solution you recommended, and it worked for me - thank you!

However, I find the current setting a bit unintuitive from a user experience perspective.

I’d like to suggest an improvement: it would be helpful to allow users to define the parameter scope directly within the Code Mappings dialog. Since this is where users configure the structure of the generated C++ code, adding a "Scope" column - where one could choose between 'static' and 'local' - would make the configuration more transparent and user-friendly.

Thanks again!
