Access to realtime clock?
Posted: Thu Apr 21, 2016 9:40 pmHi,
Newbie to the scene here... have a Sparkfun Thing and having fun learning. I'm using ESP.deepSleep() to save power, and I guess that means it's like rebooting every time the chip comes out of sleep mode. So this is perhaps a 2-part question, but:
1) is it possible to save information before going to sleep that will be there when we wake up again? Seems like: no, unless you save it to flash...
2) What I'm really interested in is elapsed time. So, is it possible to read the realtime clock from the Arduino environment?
Thanks,
Charles
