I don't remember. It was probably just a known point in time to base the frequency on. Maybe look in the DS3231 (iirc) datasheet for clues.
@tannewt yeah the DS3231 alarm registers specify the time up to the day (date). Not sure how you want this helper library to handle it, but at the very least the docs should include a warning.
PR to update the doc would be great!
When reading an alarm set point, the
tm_year
attribute is hardcoded to return 2017 andtm_mon
to return 1. Is this intentional? Caused by a limitation somewhere?https://github.com/adafruit/Adafruit_CircuitPython_Register/blob/d37349183b82cd7d05af57a77eb3765e17e7be3f/adafruit_register/i2c_bcd_alarm.py#L154
In contrast, reading the datetime properly returns the year reported from the RTC:
