Customizing a Button in Simulink to Receive Input and Display Output

Hello everyone,

I'm working on a Simulink and Stateflow project and would like to create a custom button that can both receive user input and display output based on certain conditions or calculations within the model. Specifically, I want the button to:

1. Accept input when pressed.
2. Display the result or change its appearance (e.g., color or label) based on the outcome of specific conditions or computations in the Simulink model.

Is it posible to implement in Simulink?

Thank you in advance for your assistance.

Best regards,

Hi @Nguyen,

Yes, it is possible to create a custom button in Simulink that can receive user input and display output based on certain conditions or calculations.

• Use the customizable Push Button block from the Simulink library. You can find it by typing Push Button in the Simulink quick insert menu.
• Set the button to accept input when pressed. You can configure the button to change the value of a connected variable or parameter during simulation.
• Use the PressFcn and ClickFcn callback functions to specify actions when the button is pressed and released.
• You can change the appearance of the button (e.g., color or label) based on specific conditions or computations in your Simulink model. This can be done using Stateflow or MATLAB functions to update the button's properties dynamically

Refer to the following documentations:

• Design Custom Buttons
• Push Button

I hope this helps.

Hi @Manikanta Aditya,

Thanks for your answer.

In the two documents you provided, I don’t see an example of a custom button that can receive user input and display output based on certain conditions or calculations. I also can't find an example of it elsewhere. Can you provide one?
