The RTOS source file FreeRTOS/source/event_groups.c must be included in the build for the xEventGroupGetBitsFrom() function to be available. Parameters: xEventGroup   The event group being queried. The event group must have previously been created using a call to xEventGroupCreate(). Returns: The value of the event bits in the event group at the time xEventGroupGetBitsFromISR() was called.
