# 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](https://crates.io/crates/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", 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));
|
|
}
|
|
}
|
|
```
