k8056

实现与k8056继电器卡通信的库crate，使用Rust编写。

此库提供基本的structs和enums，它们提供所需的ACSII指令，用于与Velleman制造的K8056 8通道继电器卡通信。要向继电器卡发送指令，需要一个如serialport的串行库。

使用serialport库的示例

use serialport;
use k8056::uart::{Command, Idx};
use std::thread;
use std::time::Duration;  

fn main() {
    let mut port = serialport::new("/dev/ttyUSB0", 2_400)
        .timeout(Duration::from_millis(10))
        .data_bits(serialport::DataBits::Eight)
        .parity(serialport::Parity::None)
        .stop_bits(serialport::StopBits::One)
        .open()
        .expect("Failed to open port");
    // Just a bunch of Commands to show how to initialize them
    let cmd = Command::Byte(0x1C);
    let cmd = Command::Emergency;
    let cmd = Command::Force;
    let cmd = Command::Display;
    let cmd = Command::Address(Idx::new(2));
    port.write(&cmd.to_bytes(1)).expect("Write failed!");
    for i in 1..9 {
        let cmd = Command::Toggle(Idx::new(i));
        port.write(&cmd.to_bytes(1)).expect("Write failed!");
        thread::sleep(Duration::from_millis(1000));
    }

    for i in (1..9).rev() {
        let cmd = Command::Toggle(Idx::new(i));
        port.write(&cmd.to_bytes(1)).expect("Write failed!");
        thread::sleep(Duration::from_millis(1000));
    }
}
