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.

Examples of CI flows

Now we will look at implementing three different types of CI flows, ranging from very simple to more advanced. As referenced in Chapter 3, Selecting the Right Tools, automated testing environments have a natural trade-off: simpler implementations often lead to less test replicability and setup longevity, and vice versa. The goal of showing these three examples is to reduce the barrier to implementing a quality CI flow for your specific project’s needs.

The three examples will be as follows:

  • Simple test scripts
  • In-house board farm setup
  • A virtual farm with AVH
