Hello,
I'm using Embbeded Coder to generate code which is included to a superordinated C project.
This superordinated C project need to access some data, defined in matlab.
Since this data need to be accessible to compile-time, it need to be generated by Embedded Coder as:
static const float MyNumber = 42.0f;
How to achieve this?
Thank you very much.

In either the Model Workspace or a Data Dictionary linked to your model, create a Simulink.Parameter object and name it "MyNumber". Give it data type 'single' and value 42.0. Go to the Code Generation tab, and select as Storage class 'Const'.

This makes the MyNumber appear in the model.c file. But how to add it to the model.h file, to make the constant value visible to the superordinate c-project? Thank you.
