Introduction to ComChan

Comchan (short for "Communication Channel") is a blazingly fast, minimal, and beginner-friendly serial monitor made with 💖 in Rust.

It’s built for makers, tinkerers, students, embedded developers — anyone who works with serial-connected devices like Arduino, ESP32, Teensy, or Raspberry Pi, and wants a clean, modern, and reliable way to talk to them from the terminal.

Note

🚀 Whether you're debugging a sensor or sending messages to a microcontroller — Comchan is your calm, capable companion.

Why ComChan

Most serial tools out there are either:

❌ Too basic (like screen, which doesn’t handle inputs well)
❌ Too bloated (like GUIs you don’t need)
❌ Confusing for newcomers

Comchan is:

🧼 Minimal – Does one thing and does it well
⚡ Fast – Built in Rust with snappy performance
🎨 Pretty – Uses emoji + colored output for clarity
🧠 Smart – Handles line buffering, timeouts, and clean exits
✍️ Simple to Use – Just tell it your port and baud rate and you’re set!

What can it do ?

📥 Read data from your Arduino or ESP32 or any microcontroller for that matter
📤 Send messages directly to your device
🧃 See real-time communication as it happens
🎨 Colorful logs that are clean and easy to follow
🙋‍♂️ Beginner-safe – Doesn’t crash on common mistakes
📊 Real-time data visualization from your microcontroller

Sample Use

# For Linux Users 
comchan -p /dev/ttyUSB0 -r 9600

# OR 

comchan --port /dev/ttyUSB0 --baud 9600

# For Windows Users 
comchan -p COM3 -r 9600

# OR 

comchan --port COM3 --baud 9600

The Goal

Comchan was built to make embedded development more joyful, less frustrating, and a little bit cute 🐣. Whether you're writing your first Serial.println("Hello"), or debugging complex protocols, Comchan will stay out of your way and do exactly what you ask.
