Using I2C bus with LCD modules

Projects Programming

Hi All,

Setting up the LCD module with the "LiquidCrystal_I2C" library using the line

" LiquidCrystal_I2C lcd( 0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE );" is it possible to use other ports for the

SDA and SCL lines? The reason being to tidy the pcb layout, where it would be better to use say A6 and

A7. At present I have it operating via an I2C interface module using power pins and just SDA and SCL

lines. Any info on using that library would be fine.

Cheers ......... Mike B

No, the capability is

hardwired to those

particular pins.

and, anyway, A6 and A7 are input only pins.
