In embedded systems, the quality of code is crucial for long term reliability and efficiency. The Clean Code principles, as outlined in Robert C. Martin’s influential book Clean Code, are widely used in general software development and can significantly enhance embedded C development. This article explores how these principles can be applied to embedded C, drawing on extensive experience to improve code readability, reduce technical debt, and lower costs over the system’s lifetime. Whether you’re a developer or a manager, this guide offers practical insights into integrating Clean Code into your embedded systems projects.

As software touches every part of life, people expect higher standards for quality, security, and reliability. The Cyber Resilience Act (CRA) reflects this shift - a necessary response to past industry mistakes. Rather than resisting, we can use this regulation to improve our practices. Here’s why regulation is necessary, how we reached this point, and how we can use it to create better software.
