Summary
This early blog introduces using C++ on microcontrollers by building a basic I/O library step by step. Readers will see how object-oriented features are applied to create a simple output-pin class and learn the practical trade-offs of C++ in bare-metal firmware.
Key Takeaways
- Encapsulate GPIO access in a C++ output-pin class to improve readability and reuse
- Apply inline functions and simple templates to achieve zero-overhead abstractions
- Implement direct memory-mapped register access safely within C++ idioms
- Evaluate object-oriented trade-offs (code size, performance, clarity) for resource-constrained systems
Who Should Read This
Embedded developers with basic C/C++ and microcontroller experience who want to apply C++ idioms to bare-metal firmware and I/O driver design.
