Crate can_decode 

can_decode

Decode / parse CAN frames into messages/signals in a fast and easy way.

Features

• Parse DBC (CAN Database) files
• Decode CAN messages into signals with physical values
• Support for both standard and extended CAN IDs
• Handle big-endian and little-endian byte ordering
• Support for signed and unsigned signal values
• Apply scaling factors and offsets

Example

use can_decode::Parser;
use std::path::Path;

// Load a DBC file
let parser = Parser::from_dbc_file(Path::new("my_can_database.dbc"))?;

// Decode a CAN message
let msg_id = 0x123;
let data = [0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC, 0xDE, 0xF0];

if let Some(decoded) = parser.decode_msg(msg_id, &data) {
    println!("Message: {}", decoded.name);
    for (signal_name, signal) in &decoded.signals {
        println!("  {}: {} {}", signal_name, signal.value, signal.unit);
    }
}

Structs

DecodedMessage
