wake-rs is a library written in Rust for encoding/decoding Wake protocol.

Wake is a serial communication protocol highly optimized for microcontrollers. It based on SLIP protocol (https://datatracker.ietf.org/doc/html/rfc1055).

• unique start symbol
• 7-bit addressing (optional)
• CRC (8 or 16 bits)
• low overhead

The protocol doesn't support:

• error correction
• compression

Frame structure:

There are many architecture-specific implementations:

• MCS-51
• AVR
• STM32
• x86

in many languages:

• C
• C++
• C#
• Python
• Rust

1. Demo - basic usage
2. Serial - how to use with serial port
3. Relay shield - PC <-> device communication

Add to your Rust project:

cargo add systemd-wake

Create, encode and decode packet:

use wake_rs::{Decode, Encode};

fn main() {
    let wp = wake_rs::Packet {
        address: Some(0x12),
        command: 3,
        data: Some(vec![0x00, 0xeb]),
    };

    let encoded = wp.encode().unwrap();
    let decoded = encoded.decode();
}

Build library:

cargo build --release

Build examples:

cargo build --examples

• Use this library with a microcontroller (nostd)
• Add a stream decoder (one byte per time with internal buffer)
