Bare-metal C programming for ARM is a comprehensive guide that delves into the intricacies of programming for the ARM architecture using the C programming language. This book is a must-have for anyone looking to learn bare-metal programming on ARM-based systems, whether they are beginners or experienced programmers.

The book begins with an overview of the ARM architecture and the basics of C programming. It then covers the tools needed for bare-metal programming, including the GNU Compiler Collection (GCC) and the GNU Debugger (GDB). The author explains how to set up a development environment, compile and debug code, and work with memory-mapped I/O.

One of the strengths of this book is the way it gradually builds up the reader’s understanding of bare-metal programming. The author starts with simple examples and gradually introduces more complex topics such as interrupts, timers, and peripheral devices. Each chapter includes practical exercises that reinforce the concepts covered.

The author also covers the various ARM processors, including the Cortex-M0, Cortex-M3, and Cortex-M4, and shows how to write code that is portable across different processors. The book includes a chapter on optimizing code for performance, which is essential for embedded systems where resources are limited.

The book also covers advanced topics such as real-time operating systems (RTOS), which are commonly used in embedded systems. The author provides an overview of popular RTOSes such as FreeRTOS and uC/OS, and shows how to use them to build complex systems.

Overall, Bare-metal C programming for ARM is an essential resource for anyone looking to learn how to program for ARM-based systems. The book is well-organized, easy to follow, and includes plenty of practical examples and exercises. Whether you are a beginner or an experienced programmer, this book will help you develop the skills you need to build complex embedded systems using the ARM architecture.
