I have a question about how to union in simulink in simulink coder.
I know how to create the bus of struct using the 'Simulink bus' in dictionary file. (*.sldd)
However, i can't see the part that creates the union.
Does Mathoworks support the method of generating code an union as shown below?
If so, could you tell me how?
thank you
typedef union
uint32 R;
uint16 H;
} Test_u;

I have a question about your link.
I found the 'TempBus' in *.m file. And its configuration of code generation is as follow:
Data scope : Imported
Header file : DataTypeImport.h
However, i don't find the DataTypeImport.h file.
Could you tell me where it is? How can i get that?

Following up on this as well, how is the header supposed to look/are there any examples?

Current Simulink bus does not support union. Could we get a clearer understanding of why you want to realize the Simulink.Bus object as a union in the generated code? Is there any particular use case for this request?

I respond to that.
If there are many flags (for example, Fault Flags), i can save memory space by using union.
This is only my opinion.
