2 LCD Screens?

Can I control 2 LCD screens by using the same pins for both, except different enable pin?

Should be able to, though I haven’t tried it with an Arduino (done it with a PIC)

That is exactly what is being done in the 40x4 displays. In that case the '2 LCD screens' are combined in the same package and the standard 14 (or 16 with backlight) pin interface has an additional Enable pin.

Thanks guys :)

You can by using seperate EN pins, but i would say be carefull, i’ve had problems, make sure both displays have R/W going to ground, you dont want both displays writing to the bus at the same time and you don’t want one display talking to the other

you dont want both displays writing to the bus at the same time and you don't want one display talking to the other

The separate Enable pins is what keeps this from happening. As long as you don't pulse them at the same time you will be OK regardless of the R/W levels.
