🛠️ Lightweight i2c scan & 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 I2C

✨ 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 = { version = "0.1.1", 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);

📚 Documentation

🚀 Binary Size Optimisation

Since dvcdbg is designed for a no_std environment, it is important to minimise the final binary size.

Enabling LTO (link-time optimisation) and strip during release builds will remove unused code from dvcdbg and other dependent crates, significantly reducing the binary size.

Add the following settings to your application's Cargo.toml.

# Cargo.toml (application side)
[profile.release]
lto = true
strip = true

🛠️ Supported environments

  • Rust no_std
  • AVR ( Arduino Uno )
