Embedded C++ vs C for Firmware: When to Use Which
5 min read
Most firmware is still C; C++ is common in complex and safety-related systems. When to choose which.
Smaller runtime, no surprise constructors or exceptions. Universal toolchain and MISRA C support. Best for very small MCUs, legacy codebases, and teams that want minimal abstraction.
Better abstraction (types, RAII, templates) and still deterministic if you avoid RTTI and exceptions. MISRA C++ exists for safety. Best for larger systems, object-oriented design, and when you want stronger type safety.
Complex state machines, multiple subsystems, and reusable drivers benefit from C++. When you need MISRA or safety, both C and C++ are viable; pick based on team and ecosystem. At Hendoi we write firmware in C and C++ for USA, Canada, and Bengaluru. Contact us.
