A developer shares their journey building a guitar training tool using embedded Rust, starting with a terminal-based tuner that uses audio input and FFT analysis. The project evolved from a personal need to optimize guitar learning and was developed under the pressure of an accepted conference talk. It explores the intersection of embedded systems, terminal UIs, and music technology using Rust.
Background
Rust is increasingly being used in embedded systems development due to its memory safety guarantees and performance. The Ratatui project recently added embedded device support, enabling terminal UI applications on platforms like ESP32.
