Open Tsoupakas opened 2 years ago

Tsoupakas commented 2 years ago

Hi cbm80amiga , The watch working very good however when i disconnect the usb cable ,leave it without power lets say for 10 mins and turn it back on, time is starting from last compile/upload time. Could you please advise how can fix this issue? ps: I use the Adafruit DS3231 Precision RTC

It seems that 3V battery in your RTC module died, try to replace it and check again.

I checked the whole circuit with the RTClib.It works fine.I mean when i disconnect the power supply and connect it after some time,the time is saved in ds3221 memory and running with the help of the battery.

I think you must advise me for a change maybe in your rtc.h code or in main code.which line is related with the 'save of time'?
