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.

Looking at some available SDKs

To give you a glimpse of the wide variety of SDKs available, let’s discuss a few of them. One thing you will pick up quickly is that it is easy to tell how many microcontrollers are available from a vendor by the initial look at the SDK. Vendors who are new to the market, such as the Raspberry Pi 2040, look very different from NXP or ST who have hundreds of different devices and are trying to support them with a common set of tools and software.

Raspberry Pi

Let’s start with the Raspberry Pi Pico. The Pico, released in January 2021, is a new microcontroller at the time of writing this book. One of the unique things about the Pico SDK is that it was designed to be run on a Raspberry Pi running Linux as opposed to a Windows personal computer. All of the content of the SDK is found on GitHub. There is the SDK itself and examples. The SDK relies on numerous open source tools for compilation and debugging. The build system is cmake.
