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 compilers

In the general software development industry, the term compiler may mean slightly different things to different people. A toolchain typically includes a compiler, an assembler, a linker, and a disassembler. Although not totally correct, the collection of tools may also be called a compiler. With these utilities, the source code that you write for your application, along with any software libraries you have integrated, gets converted into the final executable that runs on the Cortex-M device. As we walk through some of the toolchains available for your Cortex-M project and their features, we will also highlight the utilities in each of these toolchains that perform these functions.

Several factors can influence your compiler choice. It depends on what your target Arm processor is and whether you are more inclined to use an open source compiler (available at zero cost) or a commercial compiler (costs money). Other factors such as support from the vendor, code size...
