Summary

Jacob Beningo argues that modern embedded developers should consider migrating from C to C++ and explains three practical reasons to do so. The piece shows how C++ features can improve safety, modularity, and maintainability in firmware while remaining suitable for constrained targets and existing RTOS/toolchains.

Key Takeaways

• Identify three concrete benefits of using C++ in embedded firmware: stronger type safety, better abstraction, and improved code reuse.
• Apply modern C++ features (RAII, constexpr, scoped enums, and templates) in resource-constrained environments without large runtime cost.
• Design more maintainable and modular firmware by leveraging encapsulation, classes, and zero-cost abstractions to reduce bugs and technical debt.
• Integrate C++ with existing C-based RTOS and hardware APIs while preserving deterministic behavior and predictable resource usage.
