All Your Sketch Are Belong to modules.cpp
Somebody set up us the build. Your humble .ino sketch, with its setup() and
loop(), becomes a C++20 application importing mm.sketch, generated,
compiled, linked, and checked by modules.cpp. Take off every build.
Compiler Is All You Need
A compiler-first journey into C++20 modules, self-hosting development tools, the modules.cpp project, and a lesser programming manifesto: to do more, choose to do less.
Who Is Stella?
An AI coding agent invented a co-developer named Stella, built a confident backstory around her shared coding conventions, then caught its own hallucination a turn later with a single grep and a git log. A short field note on why every AI-generated claim gets checked against the source of truth in embedded work.
fun-plus-plus: Writing C++ Using Only c and ++
A short C++ program where every identifier is c and every operator is ++ or +=. A look at C++17 sequencing rules, uninitialized variable behavior, and the joy of being too literal.
MMCU Update: C++20 Modules for Bare-Metal Firmware
MMCU is 32bitmicro's open-source C++20 modular MCU firmware framework. This update covers the project's CMake 4.0 module-oriented scaffold, minimal main-loop starting point, and the firmware component boundaries it is designed to explore.
