  1. In this guide, you'll learn how to use interrupts and timers with the ESP8266 NodeMCU using Arduino IDE. Interrupts allow you to detect changes in the GPIO state without the need to constantly check its current value. With interrupts, when a change is detected, an event is triggered (a function is called)
  2. I need it to wake the esp up from deep sleep via RST, but then to ignore further RST activations until I programmatically send it into deep sleep again. What I really need is a proper gpio interrupt so I can ignore further resets until I go to deep sleep, but AFAIK esp8266 doesn't support gpio interrupt wake from deep sleep
  3. Now I have been unsuccesfully looking for a method to send an ESP8266 in a deep-sleep-forever mode, use an input set as interrupt receive, or its RST pin to receive the active-low signal (and hence restart the ESP8266) when the alarm is triggered in the DS3231, and wake-up the ESP8266

Hat man einen Mikrocontroller wie den ESP8266 NodeMCU im Außenbetrieb, läuft dieser oftmals über portable Stromversorgung wie bspw. Akkus, Batterien oder Powerbanks. Daher ist es von enormer Bedeutung, dass der Stromverbrauch beim ESP8266 Batteriebetrieb möglichst gering gehalten wird. Dafür hat der ESP8266 einen sog. Deep Sleep Modus, in welcher der NodeMCU inaktiv ist und somit [ The ESP8266 module has the deep sleep mode which allows to put it in hibernation to save the battery. You can wake up the module at regular intervals to make measurements and publish them on a server. The RESET pin (RST) is also used to wake the ESP8266. For example, the rising edge (the signal) of a motion detector (PIR) can be used. In this tutorial we will see the adaptations to the Arduino. As ESP8266 does not support interrupts during deep sleep, how can We accomplish this task under this particular scenario? Here, is a workaround, using couple of simple electronic components along with CH_PD, our ESP8266 will respond back to us even during deep sleep. Normally Reset, CH_PD, GPIO-0 and GPIO-2 are pulled up using 10 K resistors and GPIO-15 is pulled down the same way. But here we.
