Hi, I would like to use a real time model in H7, but compile shows some errors, as below, How to
solve it? Many thanks.

Arduino: 1.8.12 (Windows 10), Board: "Arduino Portenta H7 (M7 core)"

I hope this issue is addressed because I am experiencing the same thing.

What DS3231 library do you use?

I tried "RTC by Makuna" library and successfully compiled the included example without error.
I just compiled and not executed.(I don't have any DS3231 modules at hand right now.)
