Topic: Is it possible to use sleep and wake up with RTC/Timer in oher than Arduino Zero (Read 238 times) previous topic - next topic


Hello All:

I was interested in putting the core in sleep mode (to save power) while the RTC or a Timer is still running and wake up when the RTC/Timer expires.
I read this is only possible with Arduino Zero, but I found other micros such as ATMEGA328 and ATMEGA1284 also have RTC and the Datasheet shows low power mode numbers while RTC is still running, so I'm wondering if this could also be achieved with classic Arduino boards having those micros...



Simply put YES.
There are a myriad of libs and functions available for a variety of boards.

Simply type the name of your board and the word sleep or watchdog into google eg "arduino uno sleep"

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that I had nothing to go with in the first place so I used my wonky crystal ball.
