Best Practices & What to Avoid

Lessons learned from embedded OS development

✅ Do: Prioritize Modularity

Design with separation of concerns. Keep hardware abstraction layers clean and well-documented to enable portability across platforms.

❌ Avoid: Monolithic Designs

Tightly coupled code becomes unmaintainable. Avoid mixing hardware-specific code with application logic.

✅ Do: Test Continuously

Implement unit testing, hardware-in-loop testing, and automated CI/CD pipelines for embedded systems.

❌ Avoid: Ignoring Power

Power management must be designed from the start, not added later. Plan sleep states and power domains early.

✅ Do: Document Everything

Comprehensive documentation of interfaces, protocols, and design decisions enables collaboration and maintenance.

❌ Avoid: Premature Optimization

Profile first, optimize later. Focus on correct functionality before micro-optimizations.
