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.

The fundamentals of cloud development

Source code creation and management is the fundamental activity of software development. In the past, source code was managed inside a corporate network on a shared server using one of many version control systems. While at the office, developers accessed the source code, and when they traveled or went home, the source code could be accessed using a VPN.

Gradually, the number of version control systems shrank, and developers consolidated on Git, an open source, distributed version control system. Along the way, services such as GitHub started offering a place to store source code and collaborate with other developers.

Today, tens of millions of developers use GitHub to share code and work on software products. In recent developer surveys, more than 90% of all software developers have used GitHub on a project, revealing its ubiquity in software development. In this chapter, we will use GitHub as a starting point for exploring additional ideas...
