The board is retired and the corresponding core (https://github.com/arduino/ArduinoCore-primo) has been archived. Considering that no one is going to maintain the low power code for nRF52/Primo its better to get rid of it alltogether (and no longer advertise compatibility to 'nrf52' which - imho rightfully - seems to confuse a lot of people.
On every push that changes relevant files, and periodically, configure the repository's issue and pull request labels
according to the universal, shared, and local label configuration files.
On every push, pull request, and periodically, use the codespell-project/actions-codespell action to check for commonly
misspelled words.
In the event of a false positive, the problematic word should be added, in all lowercase, to the ignore-words-list field
of ./.codespellrc. Regardless of the case of the word in the false positive, it must be in all lowercase in the ignore
list. The ignore list is comma-separated with no spaces.
Dependabot will periodically check the versions of all actions used in the repository's workflows. If any are found to
be outdated, it will submit a pull request to update them.
NOTE: Dependabot's PRs will sometimes try to pin to the patch version of the action (e.g., updating `uses: foo/bar@v1`
to `uses: foo/bar@v2.3.4`). When the action author has provided a major version ref, use that instead
(e.g., `uses: foo/bar@v2`). Dependabot will automatically close its PR once the workflow has been updated.

This can be used to configure the ADC window interrupt on the SAMD21. It
uses OSCULP32K via GCLK6 to clock the ADC while in sleep mode (the same
as used for the EIC).
Note that attachAdcInterrupt()/detachAdcInterrupt() should be called
immediately before/after LowPower.sleep() otherwise analogRead() will
not work as expected.
There is also an example (AdcWakeup.ino) which is much like the
ExternalWakeup example but uses the ADC interrupt instead.
* Replace SerialUSB by SERIAL_PORT_USBVIRTUAL
Support boards where USB serial is named differently. E.g. the
Adafruit Feather M0 uses Serial1 as name for serial USB port.
Waking from deepSleep() is comparable to an hard reset; the sketch won't restart from the sleep invocation but the wakeuup source can be retrieved with wakeupReason()
The includes and relevant (non wrapper) functions are borrowed from Zephyr 1.5.0
The implementation is still broken:
- an RTC driver is still missing, so no timed wakeup possible
- only the AON pins configured as LEVEL can wakeup the processor
on Arduino101, the only AON broken out is RESET button
Changing the main loop in CODK-A allows operating the button without triggering a reboot. However, the board doesn't wakeup from deep sleep (am I missing something maybe?)
