freeRTOS scheduler

Posted by sapanak on December 29, 2015

Hi I have query on freeRTOS scheduler. I have enabled preemption by setting configUSE_PREEMPTION to 1. I would like to know how schduling happens if two task of same priority are ready. Does freeRTOS scheduler do time sliced round robin that is if task A and task B both are of same priority P1. While task A is running task B gets ready. Does scheduler do timeslicing or task A completes then only task B is executed.

Thanks Sapana
