Is there a way to use the external interrupt feature of Raspberry Pi? I am using Raspberry Pi model 3 B. I am trying to execute a routine only when an event(rising/falling) is detected on the GPIO pins. How can I do it?

Yes, you can use the external interrupt feature of the Raspberry Pi, including the Raspberry Pi 3 Model B, to execute a routine in MATLAB when a rising or falling edge event is detected on one of the GPIO pins. You can go through below example link as it introduces the workflow for working with GPIO pins, how to connect LEDs and push buttons to GPIO pins-

Yes, you can use the external interrupt feature of the Raspberry Pi to trigger routines when events like a rising or falling edge are detected on the GPIO pins. The Raspberry Pi has support for GPIO interrupts through libraries like RPi.GPIO and GPIO Zero. Using RPi.GPIO, you can set up event detection using add_event_detect() to monitor a pin for rising or falling edges, and then specify a callback function to execute when the event occurs.
If you need more GPIO components or accessories, Robocraze is a great option for sourcing Raspberry Pi-related hardware. They offer a wide range of components and kits, including GPIO expansion boards and sensors that can be used for external interrupts and other projects.
