Implementing C++ Coroutines on Microcontrollers

The author explores the possibility of using C++ coroutines within the resource-constrained environment of microcontrollers. The primary challenge is that the C++ standard does not natively support coroutine creation in static memory, which is critical for embedded systems. Inspired by the capabilities of modern LLM agents in generating high-quality code, the author decided to develop a custom Clang compiler extension. The project aims to provide coroutine support without relying on dynamic memory allocation. Based on this solution, the author plans to build a compact operating system tailored for microcontrollers. This approach allows for the efficient use of modern programming language features in low-level development, bypassing standard library limitations. The article is of interest to engineers focused on system software optimization and C++ development for embedded platforms, offering an innovative path for integrating high-level abstractions into the strict constraints of hardware environments.
