Posted on 2018-08-31— C++, How and Why, Improve your Code
I often encounter poorly written C++ libraries, especially around hardware. In this post I outline four practical strategies—rewrite, refactor, wrap the library, or wrap the interface—to regain control, improve reliability, and reduce pain. Read on for pragmatic steps and examples you can apply to your projects.

I show how a small C++ flags template makes embedded register bitmasks safer and much easier to read. I'll explain why macros and CMSIS-style definitions lead to errors, and walk through clear C++11 examples and a simple driver. Read on to see the implementation and usage.

I explain why preprocessor macros often cause subtle bugs and naming conflicts in C++ and share safer alternatives—const/constexpr variables, #pragma once, enums, and separate implementation files. If you want clearer, type-safe code with unchanged performance, read the full post for practical examples and replacements.

I've released Lucky World, a compact jump'n'run for the MeggyJr RGB featuring an intro, 16+ levels, secrets and an end scene. I squeezed it into ATmega328P limits and shared the sources under GPLv2. If you're curious, please read on for downloads, requirements, and play instructions.

I documented the source code for my color-changing Xmas decoration and pushed it to GitHub, adding comments and safety notes about parts you shouldn't copy. If you're curious about the implementation or want to build your own, please view the repository and the full project description for details.

I rebuilt the Meggy Jr RGB library from scratch to make game development simpler on the ATmega328P. I focused on low memory use, frame‑synchronized loops with a back buffer, clear color handling, fast pixel operations, reliable button input and a background sound player. Read the post for examples and the GitHub release.

I explain how C++ namespaces prevent name conflicts and why they matter, especially in Arduino projects. I walk through practical patterns—prefixing, selective using-declarations, and importing a namespace—with class and global examples. Read the full post for simple, pragmatic examples to keep your code clearer and conflict-free.
