/*

* This file contains the implementation for some the functions in

* idf_additions.h
|
|
*
|
|
* event group functions are split into a separate file due to the dependency chain
|
|
* xEventGroupCreateWithCaps->xEventGroupCreateStatic->event_groups.c->xTimerPendFunctionCallFromISR->timers.c
|
|
*
|
|
* In some cases this results in the weak timer task function getting overridden and
|
|
* used even if the event group functions were discarded due to not being used.
|
|
*
|
|
* Putting the event groups function in a separate file avoids this issue unless the users himself calls
|
|
* event group functions
