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.

Selecting the Right Software

Arm Cortex-M processors can execute a diverse range of software. The term “software” is so broad in the embedded and Internet of Things (IoT) industries due to the widely varying capabilities of Cortex-M processors. Firmware, middleware, libraries, and components all refer to different parts of the software stack that make up an embedded device. Further complicating matters is a lack of naming consistency, with people often referring to the same software part by different terminology. We try to use the most common software vernacular in this book.

This chapter aims to provide an overview of the different types of software commonly used in microcontroller applications, alongside information about when they should be used. Similar to the previous chapter about understanding which hardware is available in the ecosystem, this chapter presents the same context for software. It is not intended to deeply explain how each software component works...
