I want to integrate multiple files containing C Codes in a simulink model. All the files have multiple C functions which are called into other files too. How can it be done?

I have multiple files containing C codes in it. Each file has several functions that are interlinked to another file's functions also.

Now if i make a C Caller block having one source code file and another C Caller block with another source code file, will they call the function from another source code file ?

Is this possible in MATLAB to use these files in a single Simulink.

Hi Sanjay,

You can integrate existing C code into Simulink using the C Caller block. To specify source code and dependencies, you can add the names of the C files to the source code section within the custom code settings. Follow these steps to accomplish this:

1. Ensure that all your C files are organized within a single directory.
2. Navigate to Simulation > Model Configuration Parameters in your Simulink model.
3. Under the Code Generation section, select Custom Code.
4. Add your C source files to the Source files field.

For more detailed information on the custom code fields in model configuration, please refer to the MATLAB documentation on ‘Model Configuration Parameters: Code Generation Custom Code’.

For more information on Simulink C caller blocks please follow the MATLAB documentation on ‘Integrate C Code Using C Caller Blocks’.
