Thanks for the positive feedback. Please see below for my comments.
* For users who are just seeing the new examples for the first time it may not be clear how the setAlarm vs setAlarmMode works. Does the int fire when the minute register rolls over? Or is it related to setAlarm? Some initial comments at the top of the sketch would clarify things.
I agree that additional information in the examples would be extremely helpful for new users. Heck, I'm still learning my way around the Apollo3 HAL for the RTC and would put myself in that same category. I'd be happy to provide some additional insights into how the RTC functions in each example.
* Can these ints be used to wake from deep sleep? I assume so. If that's the case, please modify ex 2 to use the alarm rather than timer 6.
Yes, am_rtc_isr() can directly replace am_stimer_cmpr6_isr(). It simply becomes a matter of managing interrupts. In fact, your Artemis Examples > Advanced > LowPower_WithWake example makes use of the am_rtc_isr() to wake from deep sleep. I think a deep sleep RTC example would also be a good idea. It could be based on the Artemis low power code in the OLA repository, which is a bit more developed.
* Ex 6 - why are you triggering a rolling alarm (which to my knowledge is just an alarm that you've moved ahead by 5 seconds), but then setting the mode (https://github.com/adamgarbo/Arduino_Ap ... ms.ino#L56) to month match? What is this example trying to demonstrate?
First, the alarm mode should have been set to match every minute (6). That was a small typo. Second, the example is to demonstrate that you can have any type of rolling alarm (seconds, minutes, hours, days, months, etc.) I updated the example, which illustrates I think a bit better what I'm trying to accomplish.

I'll keep working on polishing the code and welcome any additional feedback!
