ENGaliyasser /RA3-RTOS

Star5

RA3 RTOS is an open-source real-time operating system designed for embedded systems, currently supporting ARM Cortex-M3 processors. It features efficient task management, preemptive priority-based scheduling, and inter-task communication mechanisms (semaphores, mutexes, event groups) optimized for memory-constrained environments.
