The `uecho-rs` is a portable, cross-platform development framework for Rust developers to create [ECHONET-Lite][enet] controller and device applications. [ECHONET-Lite][enet] is an open standard specification for IoT devices in Japan, it specifies more than 100 IoT devices such as crime prevention sensors, air conditioners and refrigerators.

## What is uEcho ?

The `uecho-rs` is a comprehensive framework for [ECHONET-Lite][enet] development in Rust. To implement IoT controllers or devices of [ECHONET-Lite][enet], the developer had to understand and implement the communication middleware specification such as the message format and base sequences.

The `uecho-rs` provides the following major components to control [ECHONET-Lite][enet] devices and create the standard [ECHONET-Lite][enet] devices easily without in-depth [ECHONET-Lite][enet] specification understanding. 

- [ECHONET-Lite][enet] controller to find and control [ECHONET-Lite][enet] nodes.
- [ECHONET-Lite][enet] device framework to implement any standard [ECHONET-Lite][enet] devices.
- Decoder and Encoder for [ECHONET-Lite][enet] messaging packet.
- Standard device database based on [Machine Readable Appendix][mra] and [Manufacturer code List][mcl] provided by [the ECHONET Consortium][eneto].

The `uecho-rs` handles all [ECHONET-Lite][enet] requests such as read, write and notification requests automatically. Therefore, Rust developers can implement the standard device and controller applications using the `uecho-rs` easily by simply implementing the request message validators.

## Getting Started

To add the `uecho-rs` to your project, add the following to your Cargo.toml file:

```
[dependencies]
echonet = "1.x.x"
```

`no_std` support:
```
[dependencies]
echonet = { version = "1.x.x", features = ["no_std"] }
```


The examples are available for [ECHONET-Lite][enet] controller and device implementations using the `uecho-rs`, check out [the examples folder in GitHub](https://github.com/cybergarage/uecho-rs/tree/master/examples).
