k8056

Library crate that implements the communication with a k8056 relay card, written in Rust.

This library provides basic structs and enums that provide the specified ACSII instruction, needed to communicate with the K8056 8-CHANNEL RELAY CARD manufactured by Velleman To send the instructions to the relay card, a serial library like serialport is needed.

Working example using serialport library ``` use serialport; use k8056::uart::{Command, Idx}; use std::thread; use std::time::Duration;

fn main() { let mut port = serialport::new("/dev/ttyUSB0", 2400) .timeout(Duration::frommillis(10)) .databits(serialport::DataBits::Eight) .parity(serialport::Parity::None) .stopbits(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.tobytes(1)).expect("Write failed!"); for i in 1..9 { let cmd = Command::Toggle(Idx::new(i)); port.write(&cmd.tobytes(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));
}

} ```
