This book will teach you how to design higher-quality embedded software from concept through production. Embedded systems are typically designed using microcontrollers to build electronic systems with a dedicated function and real-time responses. Modern systems need to carefully balance a complex set of features, manage security, and even run machine learning inferences while maintaining reasonable costs, scalability, and robustness.

 

This book is organized into three critical areas:

• Software Architecture and Design 
• Agile, DevOps, and Processes
• Development and Coding Skills

Embedded System Design starts with a basic introduction to embedded software architecture and the considerations for a successful design. We then break down how to architect an RTOS-based application and explore common design patterns and building blocks. Next, we discuss embedded software design processes such as TDD, CI/CD, modeling, and simulation that can be used to accelerate development. Finally, we will discuss how to select a microcontroller, write configurable code, coding strategies, techniques, and tools developers can’t live without. 

 

By the end of this book, you will have a defined development process, understand modern software architecture, and be equipped to start building embedded systems.

 

You will:

• Learn how to design and build embedded systems in a practical manner
• Understand what sound embedded system design is and how to employ it
• Explore modern development processes for quality systems
• Know where the bits hit the silicon: how to select a microcontroller
• Master techniques to write configurable, automated code
