40x4 display


I have just received two 40x4 LCD displays ( like the normal 16x2 and 20x4, blue background/white letters....but 40x4)

I was able to power up the display....but thats it. I cannot figure out where to connect all the display pins to a Mega

I can work with 16x2 and 20x4 but this 40x4 is a mystery for me at the moment

Any help would be greatly appreciated

You are still not doing very good. You might update your post with information on the display etc, a schematic (Not a fritz) for a start.
