Hi guys!For my endwork I have to control a 4x20 I²C LCD display with a Controllino PLC (variant of Arduino).
The distance between the PLC and the LCD is 20 metres. The PLC has the same pins as another Arduino.
I know that the maximum lenght of a I²C line is approximately 1m.
Is there some way I can control that?
Does somebody has experience with this problem?
I thank you.
3 meters is the maximum distance I have ran an OLED over I2C protocol using a shielded USB cable.
