Hello,
I plug my LCD SDA on IO4 and SCL on IO5 of ESP-C3-13, i execute the code on Arduino IDE, no device i2c founded (works on ESP8266).
Have you an idea about this problem?
Thank you.

Can you confirm GPIO4 and GPIO5 it's for I2C? If i understand, i2c is fixed 8 days ago on repository arduino-esp32? Me i use arduino IDE with esp32 2.0.0 rc1.

This is very simple fix, you can do try it on your local RC1 copy.

Did you try I2C scanner?
I am using currently master branch (with S2), but im pretty sure that RC2 is also fixed.
Maybe try to add SDA and SCL pins into Wire.begin(SDA, SCL);

Yes i use I2C scanner with my esp32-C3.
