Any way to use all four buttons on MagTag for PinAlarms? Moderators: adafruit_support_bill, adafruit

Hi everyone,

I was able to get the new PinAlarm code working on my MagTag to wake on button press from deep sleep:

Code: Select all | TOGGLE FULL SIZE

magtag.peripherals.buttons[0].deinit()
magtag.peripherals.buttons[1].deinit()

alarm.exit_and_deep_sleep_until_alarms(
    PinAlarm(pin=board.BUTTON_A, value=False, pull=True),
    PinAlarm(pin=board.BUTTON_B, value=False, pull=True)
)

However, I can't use all four buttons -- there is an exception that only 2 LOW pins can wake from deep sleep. Is there any workaround for this, so that I can use all four buttons to wake up? The buttons push their pins to LOW when pressed, and I'm too new at this to know if there's another way :).

Unfortunately, there is no work-around. It is a hardware limitation with this revision of the board. That's why the exception exists in the code. It's something that may change with future products, but for now, there is no way to use all four buttons as such.

I understand, thank you!
