  Quote  @ Hans - No, I've never used the EEPROM chip on these RTC's, but I expect the code Paul posted should work - MMBASIC is very good at writing to those type of EEPROM chips, and I remember seeing heaps of threads over the years of people playing with them - myself included(but not on these modules).

I have used the code for years on a DS3231 to save data and it works fine.
