Connecting Xbox Controller to Simulink Real-Time

Hi,

Im trying to add a xbox controller to my simulink Real-Time. However the only blocks I could find and use only work for normal simulink. I tried using Gamepad Simulator block and the Joystick Input block and I tested and worked only for normal Simulink. When I try to use them in Simulink Real-Time, it doesnt take the values. When I use the the JoyStick input block in simulink real-time, it gives me an error and says "Error:Unable to find S-function module 'joyinput'. S-function modules must exist as either source files or pre-compiled object files on the MATLAB path.".

Is there a way to get around this?

Thanks

Hello Ethan,

It seems that the error that you are getting is because the "Joystick Input" block was not able to create an S-function module properly which is crucial for Simulink Real-time applications. You can try re-building the application to check if the S-function module associated with the block is fixed or you can also try leveraging the following community file exchange that might suit your use case:

Additionally, you can also check out the documentation for "Gamepad Joystick" block for an alternative:

Hope it helps!

The gamepad and joystick blocks are not supported with Simulink Real-Time.

As a workaround, you could have a model running on the host computer with the Joystick Input block from Simulink 3D Animation, and sending the data via UDP to the Speedgoat real-time target computer. I.e., the joystick is connected to the host computer and send the data to the target computer via the host-target communication link. Here is an example of similar setup with host and target models exchanging data via UDP.
