Scheduler decide which task that should execute at this moment. It determines what process to run next based on priority. Consider three tasks T1,T2 and … WebApr 26, 2024 · Typically, freeRTOS uses preemptive multitasking, which can lead you to needing to guard anything shared between the tasks. That is prone to mistakes, and thus I prefer to use cooperative multitasking instead. There is an option, configUSE_TIME_SLICING, that can disable time slicing, but it only prevents the scheduler from interrupting the …

WebDec 30, 2024 · To the best of my knowledge, aside from voluntary preemption, the task scheduling is identical to that found in FreeRTOS. Tasks are assigned numerical priorities, the lower the number the higher the priority, and the highest priority ready task is given CPU time, where ties favor the currently running task. WebJul 27, 2024 · The tasks on a single core processor are never truly concurrent, but are scheduled to run as necessary depending on the scheduling algorithm. FreeRTOS is a priority-based preemptive scheduler. Your example may or not behave as you intend, but both tasks will get CPU time and run in some fashion.
