Wo RTFM helps: use GPIOs starting with 1 and that's where you get a working ADC1.

I am running into similar problems on a esp32-s2. As soon as I start to send UDP packets within short intervals, I get OSError 12 and random drop-outs. The routine I am using (within a much larger context) with uasyncio: import socket s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.sendto(dat...

Ok, as it seems it requires some debouncing.

Thanks Peter and Robert, guess I'll dig out that Oscilloscope at work

I have two light barriers connected to two GPIO inputs and the following program code to handle the status change. What I do not understand is why the irq typically fires 8x times on a status change. I now just filter it in my code, but want to understand what is happening. Any hints? import machine...

So I took this as a challenge and went ahead to build my own binary for v1.17 which did work out. Unfortunately ADC still does not work, and, seems to be broken. Any hints, anyone? MicroPython v1.17-112-g9519484c5 on 2021-10-27; LOLIN_S2_MINI with ESP32-S2FN4R2 Type "help()" for more information. >>>

So I tried loading different (unstable) versions of v1.17 but they do not seem to work at all, not sure what type of custom build Lolin created here. Does anyone know how to get the latest version to work? As an example, I get the following when loading esp32-20211026-unstable-v1.17-112-g9519484c5.b...

For me, this works on ESP8266 so I assume it also works on ESP32 .. let me know if it does. Using esp8266-20210902-v1.17.bin import ntptime import time NTP_SERVER = '0.ch.pool.ntp.org' ntptime.host = NTP_SERVER try: print('Local time before synchronization：%s' % str(time.localtime())) ntptime.settim...

Hi As it is my first post after doing lots of passive reading here, thanks for MicroPython and a great community / forum! I just got a Wemos S2 and am trying to get the ADC (1) to work. As I see in the docs it should work on GPIOs 32 - 39 , but all of them throw a 'ValueError: invalid Pin for ADC'. ...
