Add an example of graceful shutdown when SIGINT (GPIO)

[Eduardo-RFarias]

I’m new to Rust, and I’m really struggling to implement code that properly drops GPIO pins when Ctrl + C (SIGINT) is pressed. The documentation states that Rust doesn’t automatically call the drop method when a SIGINT signal is received. However, I would greatly appreciate an example of how to handle this situation.

Welcome to Rust @Eduardo-RFarias 😁 . There's an example in the examples folder that shows you how to handle signals using the simple-signal crate. Check out gpio_blinkled_signals.rs.

Hope that helps!
