Freertos task scheduler
An embedded application that uses an RTOS can be structured as a set of independent tasks. Each task executes within its own context, with no dependency on other tasks. Only one task in the application is running at any point in time. The real-time RTOS scheduler determines when each task should run. … See more SMP support in the FreeRTOS Kernelenables one instance of the FreeRTOS kernel to schedule tasks across multiple … See more Like most embedded operating systems, the FreeRTOS kernel uses a hardware timer to generate periodic tick interrupts, which are used to measure time.
