Introduction: Why the Choice of RTOS Can Be a Game Changer Choosing an RTOS (Real-Time Operating System) is one of the most strategic decisions in embedded product development. It determines how devices handle tasks, respond to events, and the reliability of cross-platform scalability. With the increasing diversity of connected devices (from low-power wearables to complex … Read more
