Any examples of projects which allow to control a LCD module over a i2c port ?

    If your LCD has a parallel interface, then you could use I2C controlled IO-expanders to control the lines of the LCD.

    Personally, I'm using 2 PCF8574 IO-expanders (I2C controlled) to control my LCD. As such, I only need to spend two pins of the processor (SDA/SCL). And I can control lots of other I2C devices too, of course.
