Bare-Metal Rust Programming: Build Reliable Firmware with Bare-Metal Rust for Microcontrollers and Embedded Systems

Master the next generation of embedded systems development with the unmatched power and safety of Rust. Bare-Metal Rust Programming is your complete, practical guide to building efficient, reliable, and scalable firmware directly on microcontrollers—without an operating system, without the standard library, and without compromises. Whether you're a seasoned embedded C developer looking to modernize your skills or a Rust programmer entering the embedded domain, this book gives you the skills, structure, and confidence to build professional-grade firmware that performs under real-world constraints.

Through clear explanations, real hardware examples, and hands-on exercises, you’ll learn how to:

• Set up a modern embedded Rust environment for bare-metal development
• Understand and apply no_std, linker scripts, memory layouts, and target specifications
• Write safe, modular drivers for peripherals like GPIO, timers, UART, SPI, I2C, and ADCs
• Manage interrupts, event-driven execution, and concurrency safely
• Implement low-power modes, sleep strategies, and optimize for energy efficiency
• Debug, flash, and monitor firmware using GDB, RTT, and probe-rs
• Structure and scale your firmware using traits, modular architecture, and platform-agnostic designs
• Build complete, production-ready projects on real microcontrollers with minimal overhead

You’ll not only build firmware that is correct—you’ll build firmware that is maintainable, testable, portable across boards, and optimized for size and speed, all while enjoying the safety guarantees Rust provides.

This book is packed with authentic working code, step-by-step instructions, and expert insights drawn from real-world embedded development practices. Each chapter builds on the last to ensure you not only understand the concepts but can apply them immediately in real deployments.
