Why Read This Book

You will learn how to build bare-metal firmware in Rust for the Raspberry Pi Pico 2 while getting a practical introduction to the RP2350’s mixed ARM/RISC-V world. The book is especially valuable if you want to move beyond toy examples and understand how to control real hardware, work directly with registers, and structure safe, maintainable embedded Rust code. It gives you a hands-on path into modern low-level development without sacrificing the rigor and safety benefits that make Rust attractive for embedded work.

Who Will Benefit

Embedded software engineers, firmware developers, and advanced hobbyists who want to write production-style Rust for the Raspberry Pi Pico 2 and understand bare-metal hardware control on the RP2350.

Level: Intermediate — Prerequisites: Basic programming experience, familiarity with general embedded concepts such as GPIO, interrupts, and microcontroller peripherals, plus a working knowledge of Rust basics.

Key Takeaways

• Set up a Rust-based embedded development workflow for the Raspberry Pi Pico 2
• Configure and build bare-metal firmware for the RP2350
• Control GPIO, timers, UART, SPI, and I2C peripherals directly from Rust

How It Compares

Covers a similar beginner-to-practical embedded Rust path as Knurling/Defmt-style learning resources and The Embedded Rust Book, but with a stronger hardware-specific focus on the Pico 2 and RP2350.
