I don't think the problem is caused by the ESP32 hardware because it runs at 100KHz when it establishes an I2C connection with any sensor. I think the important question is: Arduino Mega can work with STM8 at 100KHz. Why can't ESP32 work with STM8 at 100KHz? Why does it have to work at a lower frequ...

Hi, I have a ESP32-WROVER-E(master) and a STM8S003F3(slave). I set up I2C communication between them. I set STM8S I2C output clock frequency to 100KHz. ESP32 I2C clock frequency is the default(100KHz). But it doesn't work. I used 10K, 4.7K and 1K pull-up resistors but nothing changed. If I set the E...
