I have an OLED screen 1.5" 128x128 IC: SH1107. I can use this screen on esp32 dev board or ESP8266 without issue. If i connect to my KC868 A6 I2C bus it does not get found with i2C scan. I find its address using I2C scan on another device as 0x3C. if i go ahead and use that address in a EspHome yaml configuration to try and force a connection it fails. could this be pull up resistor issue?
