I just got a few displays that looks very much like 40x4 character, but they are 20 pins, and i suspect it to be a graphic display. The controller is a sanyo LC7980.
Does anyone know how to wire this, and plugins that support this controller. Havent found any datasheet for the controller, but i think it is compatible with T6963c controller but im not sure about that.

Any advice would be appreciated
