Hi,
I like to use the built in RTC module on the "Adafruit Grand Central M4 (SAMD51)" board. I get the following errors. I used the example that was provided by Arduino for this header file, and it came back with the same error messages, see below:

I don't know if there was a change, but:

For now we are not supporting the SAMD51. Maybe in the future :slight_smile:
