Can anyone offer advice about the correct way to use the RV3028 RTC?
I’ve written a simple class in Python that requires the Backup Switchover Mode to be set on initialisation, and it’s initialised to Level Switching Mode.
I then write the current time, date and weekday into registers 0x00 to 0x06
The RV3028 then keeps good time. The time and date are usually restored successfully after a power cycle but not every time. About 1 out of 3 power cycles results in a reset to factory values.
Have I missed a critical configuration step or is it possible this is a hardware/battery issue?
Any ideas welcomed!
