Crate sysfs_gpio [−] [src]
GPIO access under Linux using the GPIO sysfs interface
The methods exposed by this library are centered around
the Pin
struct and map pretty directly the API exposed
by the kernel in syfs (https://www.kernel.org/doc/Documentation/gpio/sysfs.txt).
Examples
Typical usage for systems where one wants to ensure that the pins in use are unexported upon completion looks like the following:
extern crate sysfs_gpio; use sysfs_gpio::{Direction, Pin}; use std::thread::sleep_ms; fn main() { let my_led = Pin::new(127); // number depends on chip, etc. my_led.with_exported(|| { loop { my_led.set_value(0).unwrap(); sleep_ms(200); my_led.set_value(1).unwrap(); sleep_ms(200); } }).unwrap(); }
