Embedded Software Design

Design higher-quality embedded software from concept through production. This book assumes basic C and microcontroller programming knowledge and is organized into three critical areas: Software Architecture and Design; Agile, DevOps, and Processes; and Development and Coding Skills.
You'll start with a basic introduction to embedded software architecture and the considerations for a successful design. The book then breaks down how to architect an RTOS-based application and explore common design patterns and building blocks. Next, you'll review embedded software design processes such as TDD, CI/CD, modeling, and simulation that can be used to accelerate development. Finally, the book will examine how to select a microcontroller, write configurable code, coding strategies, techniques, and tools developers can't live without.

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. 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. What You'll Learn

• 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
