- Correct Prototype Matching: Ensure that the function prototype defined in the .h file matches the input and output specifications of the Function Caller block in Simulink.
- Multiple Definition Conflict: If the function is defined in multiple places (e.g., in both the .h file and somewhere within the Simulink model), this could cause a conflict. Make sure the function is only defined once.
- Model Configuration Parameters: Check the Simulink model configuration parameters for code generation. Ensure that the model is set up to include the .h file and that the function prototype is being imported correctly.
- Function Call Subsystem: If the function you're trying to call from the .h file is part of a Simulink Function block or a MATLAB Function block, ensure that the function call is set up correctly and that there are no naming conflicts.
- C Caller Block: If you are using the C Caller block, you need to make sure that the .h file is specified correctly in the block parameters and that the C Caller block is configured to match the function signature.
- Simulation Target vs. Code Generation Target: Sometimes, Simulink models are set up differently for simulation versus code generation. Check if there are any pre-processor directives (like #ifdef or #ifndef) in the .h file or the generated code that may be causing the code to be excluded during simulation.
- External Code Integration: Verify the settings under "Simulation Target > Custom Code" in the Simulink model configuration parameters to ensure that your .h file is correctly integrated and that the path is correct.
- Compiler and Linker Settings: Check the compiler and linker settings in the model configuration to ensure they are set up correctly to find and use the .h file during the build process.
