To cross-compile on RaspberryPi, follow these instructions: https://github.com/Ogeon/rust-on-raspberry-pi

#Example

```rust
#![allow(deprecated)]
extern crate cylus;

use cylus::Cylus;

fn main() {
    println!("Starting..");
    let gpio = Cylus::new(24);
    for _ in 1..10 {
        println!("{}", gpio.read());
        gpio.high();
        
        std::thread::sleep_ms(1000);
        println!("{}", gpio.read());
        
        gpio.low();
        std::thread::sleep_ms(1000);
    }
}
