I understand that you're looking to simulate a microcontroller in Simulink and eventually move towards simulating the specific microcontroller that will control your system.
To start, you can explore the Simulink Support Package for your specific target hardware. MathWorks provides support packages for a variety of microcontroller platforms, such as Arduino, Texas Instruments, STMicroelectronics, and more. These packages include specialized blocks that emulate the input/output features of the microcontrollers and facilitate code generation for deployment on actual hardware. You should install the relevant support package for your microcontroller by using the MATLAB Add-Ons menu.
With the support package installed, you can begin by creating a simple model that represents a basic behaviour or functionality you want to implement on the microcontroller. For example, you might simulate the blinking of an LED. This involves using blocks from the support package, such as a 'Digital Output' block to represent the LED and connecting it to a 'Pulse Generator' block to create the blinking effect.
The next phase involves configuring your model to reflect the microcontroller's settings. This is done through the Model Configuration Parameters, where you can select your microcontroller from the Hardware Implementation tab and adjust other settings like clock configuration and code generation options. Running simulations at this stage helps you validate the behaviour of your model and ensure that the output aligns with your expectations.
When your model behaves as intended, you can proceed to Hardware-in-the-Loop (HIL) testing. This involves connecting your microcontroller to your computer and deploying the model to the microcontroller using the blocks provided by the support package. You can then run the model on the microcontroller and observe the outputs to verify the hardware behaves as simulated.
When your Simulink model thoroughly represents your system, you can use tools like ‘Simulink Coder’ or ‘Embedded Coder’ to generate C code from the Simulink model. This code can then be compiled and flashed onto your microcontroller.
