How do I prepend a variable declaration with a qualifier in my generated code?
显示 更早的评论
I am generating C code and I want to add a macro before the variable declarations.
Currently, my generated code looks as follows:
/* Exported block parameters */
float32 variableName = 0.5F; /* Variable: variableName
* Referenced by: '<S5>/Constant1'
*/
I want to add a macro, which is defined in an external header file such that my generated code is as follows:
/* Exported block parameters */macro float32 variableName= 0.5F; /* Variable: variableName
* Referenced by: '<S5>/Constant1'
*/
How do I do this?

There are 2 possible ways to prepend the variable declarations in your generated code with a macro, depending on where these parameters are defined in your model.
Parameters Defined in Model Workspace
You can map the parameter to "ConstantMemory" and use additional native type qualifiers to prepend the keywords, by setting "AdditionalNativeTypeQualifier" to be 'macro'.
You can find more about this in the documentation here: https://www.mathworks.com/help/releases/R2021b/autosar/ug/map-model-elements-using-simulink-autosar-mapping-explorer.html#mw_f8f8aab0-d352-46e0-ae2f-9b3e3bdf5da9
Parameters Defined in Base Workspace or SLDD (Simulink Data Dictionary)
You can define a new storage class, assign a memory section with the defined qualifier and map this storage class to the required parameters. You can do this as follows:
- Define a new storage class and assign a memory section with the required qualifier:
- Map this storage class to the required parameters:
