How to Deploy Simulink Model to Arduino Quickly

To deploy a Simulink model to an Arduino, first configure the model for Arduino hardware by selecting the Arduino board in the Hardware Implementation pane. Then, use the Deploy to Hardware button in Simulink to automatically generate code and upload it to the Arduino device.

Syntax

Deploying a Simulink model to Arduino involves these main steps:

• Set Hardware Board: Choose your Arduino board in Simulink's Hardware Implementation settings.
• Configure Model: Adjust model parameters to match Arduino capabilities.
• Build and Deploy: Use the Deploy to Hardware button to generate code and upload it.

1. Open your Simulink model.
2. Go to Model Settings > Hardware Implementation.
3. Select 'Arduino Uno' (or your board) as Hardware board.
4. Click 'Deploy to Hardware' button on the toolbar.

Example

This example shows how to deploy a simple LED blink model to Arduino using Simulink.

text

1. Open Simulink and create a new model.
2. Add a 'Pulse Generator' block to create a square wave signal.
3. Add an 'Digital Write' block from the Simulink Support Package for Arduino Hardware.
4. Connect the Pulse Generator output to the Digital Write block input.
5. Set the Digital Write block pin to 13 (built-in LED).
6. Set Hardware board to 'Arduino Uno' in Model Settings.
7. Click 'Deploy to Hardware' to upload the model.

// The LED on pin 13 will blink on and off based on the pulse generator.

Output

The Arduino's built-in LED on pin 13 blinks on and off at the pulse frequency.

Common Pitfalls

• Wrong Hardware Selection: Not selecting the correct Arduino board causes deployment errors.
• Unsupported Blocks: Using Simulink blocks not supported on Arduino will fail code generation.
• Pin Conflicts: Assigning pins used by other hardware features can cause unexpected behavior.
• Missing Support Package: Forgetting to install the Simulink Support Package for Arduino blocks deployment.

/* Wrong way: No hardware selected */
// Trying to deploy without setting hardware board

/* Right way: Set hardware board */
// In Model Settings > Hardware Implementation, select 'Arduino Uno'

/* Wrong way: Using unsupported block */
// Using blocks like 'MATLAB Function' without support

/* Right way: Use supported blocks only */
// Use blocks from Arduino Support Package

Quick Reference

Step	Action	Notes
1	Open Simulink model	Start with your designed model
2	Set Hardware Board	Model Settings > Hardware Implementation > Select Arduino board
3	Use Supported Blocks	Use Arduino Support Package blocks for I/O
4	Connect Arduino	Plug in Arduino via USB
5	Deploy to Hardware	Click 'Deploy to Hardware' button to build and upload
6	Test on Device	Observe Arduino behavior (e.g., LED blinking)

Key Takeaways

Always select the correct Arduino board in Simulink Hardware Implementation settings before deployment.

Use only Arduino-supported blocks to ensure successful code generation and deployment.

Install the Simulink Support Package for Arduino to access hardware-specific blocks and deployment tools.

Use the 'Deploy to Hardware' button to automatically generate code and upload it to your Arduino device.

Check pin assignments carefully to avoid conflicts with Arduino hardware features.
