About µOS++ Reference
A POSIX-inspired open-source real-time operating system (RTOS) framework written in C++. µOS++ provides a rich set of kernel objects including threads, semaphores, mutexes, event flags, message queues, memory pools, and software timers. It aims for high quality with references to industry standards like MISRA and IEEE. The project is distributed under the MIT license and is designed for embedded systems.
