It introduces a completely rewritten scheduler using a binary min-heap, replacing the original scheduler of FreeRTOS. Some API functions of FreeRTOS have also been changed to work together with the new scheduling policy.</p> <p><strong>Please note that deadlineRTOS is highly experimental software and not meant for production use!
