C17-based extended standard library, cross-language type system, and unit testing framework targeting Dreamcast, Gamecube, PSP, PSVita, Windows, Mac, Linux, Android, iOS, and WebAssembly.

The C Object Oriented Programming Library

A lightweight, event-driven micro kernel for high-reliability bare metal embedded systems, featuring asynchronous event bus, robust fault management, and advanced deep-sleep power strategies. Optimized for STM32L4 series.

Lightweight async Event-driven microkernel for the B-L4S5I-IOT01A development board (STM32L4S5VITx, Cortex-M4F).

C23-based, cross-platform, backend-agnostic UI library.

Object-Oriented C Language is a pure C project that mimics object-oriented programming using structs and function pointers. Implements core OOP concepts in C (C99) using structs and function pointers, without external libraries.
