# pelcodrs

`pelcodrs` is a Rust library for communications using the Pelco D protocol.

The Pelco D protocol is widely used for controlling PTZ cameras, especially
in the CCTV industry.

[Crates.io](https://crates.io/crates/pelcodrs)
[Documentation](https://docs.rs/pelcodrs)

## Simple usage

Add this in your application `Cargo.toml`:

```rust
[dependencies]
pelcodrs = "0.2.0"
```

Create message objects to send to the device:

```rust
use pelcodrs::*;

let msg = MessageBuilder::new(10)
    .camera_on()
    .focus_far()
    .down()
    .tilt(Speed::Range(0.5))
    .finalize()?;

assert_eq!(&[0xFF, 0x0A, 0x88, 0x90, 0x00, 0x20, 0x42], msg.as_ref());
```

A port object can be used with any `Read + Write` object for communicating with
the target device. For example, a `SerialPort` object from the crate
[serialport](https://crates.io/crates/serialport) can be used as port:

```rust
use serialport;
use pelcodrs::*;

let dev = PelcoDPort::new(serialport::open("/dev/ttyS0"));
dev.send_message(Message::flip_180(10)?)?;
```
