Struct Button

Source

pub struct Button { /* private fields */ }

Available on crate feature ev3 only.

Expand description

Ev3 brick button handler. Opens the corresponding /dev/input file handlers.

This implementation depends on the availability of the EVIOCGKEY ioctl to be able to read the button state buffer. See Linux kernel source in /include/uapi/linux/input.h for details.

use ev3dev_lang_rust::Button;
use std::thread;
use std::time::Duration;

let mut button = Button::new()?;

button.set_down_handler(|is_pressed| {
    println!("Is 'down' pressed: {is_pressed}");
});

loop {
    button.process();

    println!("Is 'up' pressed: {}", button.is_up());
    println!("Pressed buttons: {:?}", button.get_pressed_buttons());

    thread::sleep(Duration::from_millis(100));
}
