WiringPi Rust绑定

使用Rust使WiringPi可访问的API包装器。它实现了最重要的功能，并提供了一些类型系统便利。

要将以下行添加到您的 Cargo.io 以使用 rust-wiringpi

[dependencies]
wiringpi = "0.2"

示例：闪烁灯

extern crate wiringpi;

use wiringpi::pin::Value::{High, Low};
use std::{thread, time};

fn main() {
    //Setup WiringPi with its own pin numbering order
    let pi = wiringpi::setup();

    //Use WiringPi pin 0 as output
    let pin = pi.output_pin(0);

    let interval = time::Duration::from_millis(1000);

    loop {
        //Set pin 0 to high and wait one second
        pin.digital_write(High);
        thread::sleep(interval);

        //Set pin 0 to low and wait one second
        pin.digital_write(Low);
        thread::sleep(interval);
    }
}

使用Cargo交叉编译

遵循此 指南。

cargo build --target=arm-unknown-linux-gnueabihf   # Older models
cargo build --target=armv7-unknown-linux-gnueabihf # Newer models

Orange Pi支持

rust-wiringpi 还可以包装Orange Pi SBC板卡的WiringOP库。这可以通过 orangepi 功能启用

[dependencies.wiringpi]
verson = "0.2"
features = ["orangepi"]

开发模式

在开发模式下，rust-wiringpi 被编译为一个不包括原始WiringPi的rust-native库。绑定函数被替换为输出简单日志到stdout的模拟函数。使用此模式，您可以在不支持WiringPi的平台构建和调试项目。

# build
$ cargo build --features wiringpi/development

# run
$ cargo run --features wiringpi/development
