Modern Embedded Systems Programming Course - #26 RTOS Part-5: What is "real-time"? Preemptive, priority-based scheduling

In this fifth lesson on RTOS I'll finally address the real-time aspect in the "Real-Time Operating System" name. Specifically, in this lesson, you will augment the MiROS RTOS with a preemptive, priority-based scheduler, which can be mathematically proven to meet real-time deadlines under certain conditions.
