Quick LCD question.

Hi all.
When you are interfacing an LCD module(4x20 or something...) do you use any pull-up or pull-down resistors on data or control pins?
Thank you very much!

No, you don't need to add external pull-ups or pull-downs.

In fact, the LCD controller chips have internal pull-ups on the data bus
and RS and R/W lines.
