July 2026 Rustacean Meetup

Approximate Talk Time: 45 mins

Abstract

Most serial monitor tools are GUI-first and feel clunky in terminal-centric embedded development workflows. ComChan is a blazingly fast, minimal serial communication tool written in Rust, designed from the ground up for developers who live in the terminal.

In this talk, I share the architecture and key implementation decisions behind ComChan, including:

• Handling high-speed streaming serial I/O efficiently in Rust
• Overcoming terminal rendering challenges with modern TUI libraries
• Concurrency models, buffering strategies, and performance tradeoffs for responsive hex dumps, real-time plotting, and data export
• Designing a reliable, ergonomic CLI tool that fits naturally into embedded debugging flows (auto-detection, session replay, CSV logging, config files, etc.)

The talk draws from real-world usage supporting Zephyr RTOS, sensor-heavy firmware, binary protocols, and daily embedded workflows. It concludes with a live demo and a preview of experimental features for next-generation terminal-based hardware visualization and telemetry.

Intended Audience

Rust developers, embedded systems engineers, and CLI/TUI tool enthusiasts.
