Adafruit feather sense Internal Clock

Dimitrios Kosyvas <kosyvas14828@...>


I also have the adafruit feather sense board  with the nrf52840 processor and i am using zephyr to program it .The only way to work is for me to enable the  32k internal RC Oscillator by writing 

# 32kHz clock source - necessary for Adafruit Sense (Internal Clock!)

I was wondering if the reason for not working is that zephyr RTOS needs the RTC .

Could you explain why the initialization  of the internal 32k clock  is necessary ?
