Description

RP2040 Assembly Language Programming: Including the RP2350 and Raspberry Pi Pico 2.

Unlock the full capabilities of the Raspberry Pi Pico by learning to program its dual ARM Cortex-M0+ processors using Assembly language. This practical guide explores the RP2040 microcontroller from the ground up, helping you understand how the hardware operates at its lowest level while developing the skills needed to build faster, more efficient embedded applications.

The Raspberry Pi Pico introduced the RP2040, Raspberry Pi’s first custom-designed microcontroller, packed with powerful peripherals and coprocessors for mathematical operations and advanced input/output control. Throughout this book, you’ll discover how these components work, write optimized Assembly code, and gain a deeper understanding of embedded programming than high-level languages alone can provide.

A major focus is the RP2040’s Programmable I/O (PIO) subsystem, featuring eight dedicated coprocessors with their own Assembly instruction set. You’ll learn how to create custom communication interfaces, interact with onboard peripherals, and develop high-performance routines for a variety of hardware applications. The book also demonstrates how to combine Assembly with C, contribute to the official RP2040 Software Development Kit (SDK), and enhance your own electronics and IoT projects with low-level optimization techniques.

Updated for the Latest Hardware

This edition has been revised to support the Raspberry Pi Pico 2 and its RP2350 processor, covering new capabilities such as floating-point operations and expanded instruction sets. It also reflects the latest improvements to the Raspberry Pi Pico SDK, including enhanced support for Visual Studio Code and modern development workflows.
