Hi Everyone,

I’m actually working on a project involving many imputs. I try to use the deepsleep mode of the ESP32 with Microphyton. I used the external wake up ext1(esp32.WAKEUP_ANY_HIGH) to enable the esp32 to wake up if any of the inputs goes high. I did try the code provided by Ruis in one of the project. I changed it a bit to  figure out which pin wake up the esp32.

I used two differents led to find out which pins wake up the microcontroller. The code is working but if anyone has a more Pythonic and less tedious code. Please share with us.

Here is my code:

import machine
import esp32
from machine import Pin
from time import sleep
wake1 = Pin(32, mode = Pin.IN)
wake2 = Pin(25, mode = Pin.IN)
red_led = Pin(13, Pin.OUT)
green_led = Pin(12, Pin.OUT)
string_value = "I'm going back to sleep.I'll wake up at the next external wake up"
esp32.wake_on_ext1(pins = (wake1, wake2), level = esp32.WAKEUP_ANY_HIGH)

Code:

import machine
import esp32
from machine import Pin
from time import sleep

wake1 = Pin(32, mode = Pin.IN)
wake2 = Pin(25, mode = Pin.IN)
#Pin_notification = wake2 = Pin(33, mode = Pin.IN)
red_led = Pin(13, Pin.OUT)
green_led = Pin(12, Pin.OUT)

string_value = "I'm going back to sleep.I'll wake up at the next external wake up"

#level parameter can be: esp32.WAKEUP_ANY_HIGH or esp32.WAKEUP_ALL_LOW
esp32.wake_on_ext1(pins = (wake1, wake2), level = esp32.WAKEUP_ANY_HIGH)


while True:
    if wake1.value() == 1 :
        print("Wake1 has been tripped")
        for x in range(5):
            red_led.value(1)
            sleep(0.5)
            red_led.value(0)
            sleep(0.5)
        print(string_value)
        break
    elif wake2.value() == 1:
        print("The second switch has been tripped")
        for x in range(5):
            green_led.value(1)
            sleep(0.5)
            green_led.value(0)
            sleep(0.5)
        print(string_value)
        break
    else:
        pass

print("I'm Off")
