RTC not responding

[mburm]

Hi all,

I have a controllino mini and try to use the RTC. I put the switch in the on position and i uploaded the DemoRTC code from the provided examples. However, in the serial print, all time values are reported as zero, instead of increasing as expected. Any thoughts?

Hello,
normally zeros are reported in case of RTC switch in possition "0". Are you sure that you have switch in possition "1"?
Do you have something else connected to the CONTROLLINO please?
