Hi I have just bought this Winstar LCD:http://www.rapidonline.com/Electronic-Components/Winstar-Graphic-Display-Negative-Blue-Mode-128-x-64mm-White-LED-Backlight-57-2278
i am using the u8glib library for graphical LCDs, written by Oliver Kraus. I cant get it to work (except the backlight...)
I have it set up like this on the mega 2560:
U8GLIB_KS0108_128 u8g(7, 8, 9, 10, 11, 12, 13, 22, 23, 24, 4, 5, 25);
According to Oliver, it should be wired like this:
U8GLIB_KS0108_128 u8g(d0, d1, d2, d3, d4, d5, d6, d7, en, cs1, cs2, di, rw [, reset])
and I am trying to run the hello world example. I have checked my connections again and again, and I cant find a problem. the only confusion is the LCD nas "negative voltage output" pin, and I read that some LCD's need negative voltage. Could this be it, and if so how do I accomplish that?
I have reset wired to pin 25.
Any ideas on things to try. I cant get hello world to appear!
I have the variable pin (I assume for contrast) connect to VCC via a 10K resitor
