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.

Exploring middleware and libraries

To keep up with modern embedded design requirements, microcontrollers offer a wide range of peripherals such as a Universal Serial Bus (USB), Wi-Fi, Bluetooth Low Energy (BLE), and so on.

Developing software from scratch that utilizes these peripherals efficiently presents developers with real challenges. Easy-to-use middleware helps bridge this gap to properly leverage modern communication and interface peripherals.

Most of the RTOSs we listed in the earlier section offer a rich set of modules and middleware to help software developers easily integrate support for these peripherals in their Cortex-M devices. The following diagram shows some examples of common middleware components:

As there are so many different types of peripherals that do the same thing (Wi-Fi chips, BLE peripherals, and so on), it can feel like an overwhelming task to find the specific middleware or libraries...
