The Insider's Guide to Arm Cortex-M Development

By: Zachary Lasiuk, Pareena Verma, Jason Andrews

Overview of this book

Cortex-M has been around since 2004, so why a new book now? With new microcontrollers based on the Cortex-M55 and Cortex-M85 being introduced this year, Cortex-M continues to expand. New software concepts, such as standardized software reuse, have emerged alongside new topics including security and machine learning. Development methodologies have also significantly advanced, with more embedded development taking place in the cloud and increased levels of automation. Due to these advances, a single engineer can no longer understand an entire project and requires new skills to be successful. This book provides a unique view of how to navigate and apply the latest concepts in microcontroller development. The book is split into two parts. First, you’ll be guided through how to select the ideal set of hardware, software, and tools for your specific project. Next, you’ll explore how to implement essential topics for modern embedded developers. Throughout the book, there are examples for you to learn by working with real Cortex-M devices with all software available on GitHub. You will gain experience with the small Cortex-M0+, the powerful Cortex-M55, and more Cortex-M processors. By the end of this book, you’ll be able to practically apply modern Cortex-M software development concepts.

Booting to Main

The most prevalent language used in microcontroller development is C. The very first microcontrollers were 8-bit processors and programming was done in assembly language. Today, the microcontroller market is currently dominated by 32-bit processors, with Cortex-M holding a considerable market share. A significant amount of code is written in C, with some projects extending into C++. Python is popular for microcontroller applications and new languages such as Rust are also starting to appear, but a solid understanding of C programming is still a must for embedded developers. In this chapter, we will present how to get started with creating, building, running, and debugging C applications on Cortex-M microcontrollers. We will present the important parts of development with C. The focus is not on the language itself, but on the connection between the programming tools, the software, and the hardware.

The chapter is organized around the universal C program known as hello...
