dvcdbg

🛠️ Lightweight debug & logger crate for embedded Rust (no_std friendly)

dvcdbg is a lightweight logging and debugging output library for embedded Rust development.
It can be used in a no_std environment and supports log output via UART, I2C, etc.

✨ Features

• ✅ no_std support
• ✅ Formatless, fast and lightweight
• ✅ It also includes utilities for embedded debugging, such as an I2C scanner.
• ✅ Easy to use with simple logging and macros
• ✅ Comes with handy built-in utilities such as an I2C bus scanner
• ✅ Features can be selected with feature flags (e.g., debug_log)

📦 Quickstart

# Cargo.toml
[dependencies]
dvcdbg = { git = "https://github.com/p14c31355/dvcdbg", features = ["debug_log"] }

📄 Usage example (Arduino)

use arduino_hal::default_serial;
use dvcdbg::logger::SerialLogger;

let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
let mut serial = default_serial!(dp, pins, 57600);

let mut logger = SerialLogger::new(&mut serial);
logger.log("Init I2C bus...");

// Use `log!` macro (requires debug_log feature)
log!(logger, "Formatted number: {}", 42);
