@pstolarz are you ready with OneWireNg?

[pstolarz]

C3 works fine on my lib. Future release 0.11 will support S3 and H2.

PR #114

[PaulStoffregen]

I've merged #114. For everyone following this issue and still using ESP32, please download the latest OneWire and reply here to confirm (or deny) this fully solves the problem.

I am waiting for your feedback before publishing a new OneWire version which will make this fix available to everyone using the Arduino Library Manager. Please take a moment to test this latest code and let me know if it should be published as a release to the wider Arduino community?

I'm playing with ESP-32 (https://github.com/Hackuarium/esp32-c3/blob/main/src/taskOneWire.cpp) with various sensors and I can confirm that the head is working correctly. (and I could not let it work with the current release). Many thanks !
