Add custom code before each "step" function call in Embedded Coder

Greetings,

currently I'm developing an application firmware for my custom real-time hardware. Because of that, I want to be able to add a custom source before each "model step" is executed because of my custom device driver handler.

Currently I have the custom S blocks placed inside the model itself and scheduled with Scheduler Editor, and it works, but I want to place it outside the visible model. I've looked at the menues in "Configuration Parameters", but only thing I could find is "Aditional Source Code" that does not include what I need.

Is there a way to place the custom source cleanly without mixing it with the visible model itself?

Hi @Luka,

I understand that you are trying to add a custom code to the model "Step" function in simulink code generation process.

Based on the MathWorks documentation resources, the best and ideal way is to use the S-Function approach which you are already using, due to its better visibility within the model.

However, it should be possible to incorporate the custom code using the "STF_make_rtw_hook" file. You can find more information on the following documentation page:

I hope this helps!
