Hi,
I am working with DS3231 with arduino UNO.
i use MD_DS3231_Test example which is attached hear with.
As per example i have set Year,Month,Date,Time,Day of week.
all data are transferred on RTC chip.
but surprisingly time is not increasing as shown in attached screen shot.
The DS3231 has a status control register and the contents of this register decides whether the clock is running or stopped.
Libraries for the DS1307 generally do not touch this DS3231 register
Some libraries for the DS231 set the clock to running on initialization by default, some don't.
Which RTC library are you using, if any?
