1IntroductionImagine if the MCU we work with only runs bare-metal programs; when it reaches a thread that includes a delay, our CPU would start to “idle”.To maximize CPU utilization, we need to use an RTOS (Real-Time Operating System). In simple terms, an RTOS is an operating system that schedules all available resources to complete real-time … Read more
