@VojtechBartoska I think OneWire feature isn't working as it fails for ESP32C3 when building some DS18B20 temperature sensor. I guess it is GPIO related.

@sylvioalves DS18B20 does work with the C3. Probably your used OneWire lib is not core 2.0.x ready. See changes made in Stickbreakers OneWire lib made here arendst/Tasmota@3cb48f1

@Jason2866 I understand. However, for common users, how would they know that or which OneWire lib to use? If you type OneWire to install a new library, there happens to be more than 5 libs and at least 2 of then does not work. So what would be the recommended way of having any OneWire library working? Well, I am not following the development as is, so my question is really as an end-user one.

[Jason2866]

@sylvioalves That's in general a Arduino library problem. Many do not work reliable since the are designed to be used with many different MCU. Maybe espressif can recommend a library and supports to maintain?

[Jason2866]

@sylvioalves The maintainer of Tasmota fixed the onewire lib.

@Jason2866 thanks for the heads up!

@VojtechBartoska @me-no-dev
What do you think about adding an official OneWire library to ESP Arduino Framework?

[me-no-dev]

@SuGlider maybe a good idea :) need to refresh my memories on the protocol. Maybe we can use a peripheral, like RMT for that

FWIW, there's this IDF-specific RMT-based onewire driver you could reference: https://github.com/DavidAntliff/esp32-owb/blob/master/owb_rmt.c

@igrr this IDF-specific RMT-based onewire driver does not work with esp32-c3 though:
DavidAntliff/esp32-owb#26

[SuGlider]

I think it may not compile, but it could work with the right adjustment.

C3 has a more limited version of the RMT peripheral. It certainly needs code adjusting.

Would be great to have a adopted OneWire driver for release of v2.0.3.
