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. WebThe RTOS scheduler decides which task to run on a recurring basis, and some tasks can interrupt and run before other tasks in a process known as “preemption....
