Re: Can someone please help a noob with a Deep Sleep code?

https://thingpulse.com/max-deep-sleep-for-esp8266/ has quite a good explanation.
The unsigned 32 (with a limit of 71 minutes) was changed to unsigned 64 bit at some point. However as the article shows the real maximum is about 3.5 hours.
I am guessing that the deep sleep is controlled by a 40 bit counter driven by the 80MHz clock which corresponds approximately to this maximum period.
