A simple interface to GPIO devices with Raspberry Pi.
This library is based on GPIOZero library.
Note: This is a work in progress. The library will eventually support embedded-hal based drivers
The idea is to get started with physical computing using Rust with little coding by hiding the underlying complexity.
The library uses BCM Pin numbering
```rust
extern crate rustgpiozero; use rustgpiozero::*;
fn main() {
// Create a new LED attached to Pin 17
let mut led = LED::new(17);
// blink the LED // ontime: 2 seconds and offtime: 3 seconds
led.blink(2,3);
}
```
```rust extern crate rustgpiozero; use rustgpiozero::*;
fn main() { // Create a button which is attached to Pin 17 let button = Button::new(17); button.waitforpress(); println!("button pressed");
}
```
Compare this to using the crate sysfs_gpio to blink an LED on the Raspberry Pi :
```rust
extern crate sysfs_gpio;
use sysfs_gpio::{Direction, Pin}; use std::thread::sleep; use std::time::Duration;
fn main() { let myled = Pin::new(127); // number depends on chip, etc. myled.withexported(|| { loop { myled.setvalue(0).unwrap(); sleep(Duration::frommillis(200)); myled.setvalue(1).unwrap(); sleep(Duration::from_millis(200)); } }).unwrap(); }
```
To use rust_gpiozero, first add this to your Cargo.toml:
toml
[dependencies]
rust_gpiozero = "0.1.0"
The following features are planned :
