Thank you for your questions. No Problem. Yes, the addresses match! Yes - the frequency is the same. This is the scanning code: import machine sda=machine.Pin(0) scl=machine.Pin(1) i2c=machine.I2C(0,sda=sda, scl=scl, freq=400000) print('Scan i2c bus...') devices = i2c.scan() if len(devices) == 0: pr...

Hello, since a few days, I try to get a i2c lcd display with the PCF85744AT working.
