ESP32: RTC no function 'wake_on_ext0'

openby linuskohleropened 2018-09-15updated 2019-05-21
port-esp32

Hello,
this question may already be answered, but I can't find any working version for me.

I'm trying to use an interrupt-Pin on my newly flashed ESP32.
I tried with multiple snippets I found online (e.g. this or this), but it always breaks down to the point that RTC doesn't have the attribute now() or wake_on_ext0.

AttributeError: 'RTC' object has no attribute 'wake_on_ext0'

Is there anything I'm doing wrong? I'm using a flashed ESP32 wroom and the latest binaries from here (esp32-20180915-v1.9.4-528-gabb536da4.bin).

Thanks for your help!

S2/S3 RTC_VALID_EXT_PINS definitions

Coming around back to this one https://github.com/micropython/micropython/issues/7607

On S2/S3 variants, GPIO0 through GPIO21 are valid RTC pins. In this example, asserting pin 5 should wake.


import esp32
import machine
from machine import Pin
o = Pin(5, Pin.IN, pull=Pin.PULL_DOWN)
esp32.wake_on_ext1(pins = (o,), level = esp32.WAKEUP_ANY_HIGH) #multi-pin

machine.deepsleep(10000)

I have a local fix, working on a pull request...
