I am working on a pi hat that will cut the Pi's power in the evening when the pi isn't being used in my application. Anyways, I have a couple questions about using the DS3231 RTC.
There is a uC in the power circuit that is used as glue logic to control the load switch IC that controls the power to the pi. I need the alarm functionality of this RTC to tell the uC to apply power to the pi so that it can be turned back on. The pi will then clear the alarm, perform it's operations, then go to sleep again after setting the next alarm. Anyways, using the DS3231 as the dtoverlay, am I still able to set and clear alarms through I2C? Will this create contention between the Python I2C commands and the kernel trying to update the time of the OS? I haven't been able to find anything about this and need to determine if I need to re-design this aspect of the software.
