Hmmm, just saw the other issues related to ESP32 implemention of pinmode. If you're on ESP32 I guess that could be issue. Could be an issue with pinmode function itself...

The internal pull-ups are much weaker than the pull-ups that I2C recommends and may mean that time to go high is much longer, making communication are typical I2C speeds unreliable....
