Waking esp8266 via Pin (wemos D1)

[andrey-git]

According to the documentation here: http://docs.micropython.org/en/v1.9/esp ... .deepsleep

Pin change can be used to wake the board from deepsleep.

I tried the following:

from machine import Pin
p5 = Pin(5, Pin.IN)
p5.irq(trigger=Pin.IRQ_RISING|Pin.IRQ_FALLING)

If I change the voltage on pin5 while the board is awake - the IRQ fires fine.
However if I run machine.deepsleep() it won't wake up when changing voltage on pin5

Is this feature supported?

Yes it is supported. You must use the RST (reset) pin for this. When using RTC based wakeboard it is connected to the GPIO pin 16, which yields the reset from the internal RTC.
Check the datasheet for details and how to addept this should be straight forward.
