Task Priorities Each task is assigned a priority from 0 to ( configMAX_PRIORITIES - 1 ), where configMAX_PRIORITIES is defined within FreeRTOSConfig.h and can be set on an application by application basis. Low priority numbers denote low priority tasks. The idle task has priority zero (tskIDLE_PRIORITY). The FreeRTOS scheduler ensures that tasks in the Ready or Running state will always be given processor (CPU) time in preference to tasks of a lower priority that are also in the ready state. In other words, the task placed into the Running state is always be the highest priority task that is able to run. Ready state tasks of equal priority share the available processing time using a time sliced round robin scheduling scheme.
