I'm pretty new to programming, but i've created a data logging system that reads some data and post them on adafruit IO then the system goes in deep sleep.
All works fine except for the RTC that obviously is not so precise in keeping time. Now i need to replace with an external RTC, pcf8523 in my case, but i don't know how to keep the external RTC work when i'm in deep sleep. Any tips to do that? After 3 weeks of searching i've found nothing...
I'm using RTClib.h with Time.h and TimeAlarms.h to set alarms and use them.
My problem it's only to keep the RTC in function everytime; i think after that i will have no other problem to be solved
PS: sorry for my english
