In the design process of RTOS applications, the task switching is managed by the RTOS task scheduler, and the source code of the RTOS application cannot fully reflect the real-time behavior of a multitasking system. The real-time behavior of a multitasking system also depends on tasks, interrupts, inputs, and their interactions. Therefore, the real-time behavior … Read more
