Summary

Amar Mahmutbegovic's blog explains how to use static classes and Modern C++ idioms to write low-RAM, safer firmware for microcontrollers. Readers will learn practical patterns for grouping stateless behavior, controlling initialization, and avoiding dynamic allocation on constrained embedded targets.

Key Takeaways

• Use static classes to group related stateless functions and constants, reducing global namespace pollution and RAM usage
• Prefer constexpr, inline static members, and header-only patterns to place data in flash and avoid dynamic initialization
• Place and initialize static data explicitly (linker sections, attributes) to control startup ordering and reduce runtime overhead
• Design static class APIs to be ISR-safe and reentrant, and avoid hidden state that can break in RTOS or interrupt contexts
• Measure and optimize footprint (disable RTTI/vtables, avoid heap allocations) when adopting Modern C++ features in embedded builds

Who Should Read This

Embedded firmware engineers with intermediate C++ experience working on microcontrollers (ARM Cortex-M/RISC-V) who want to reduce RAM footprint and improve reliability using Modern C++ patterns.
