I bought RAMPS 1.4 and a full graphical LCD controller.
First thing I did was install Arduino IDE 1.05r2 on Windows 7 and the newest version of Marlin on GitHub. I also put the U8glib (included in Marlin) folder in Arduino library and uncommented #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER.
However when the LCD is plugged to the RAMPS board with two IDC connectors, the LCD just lights up blue, no text or graphic.
I'm powering with the provided computer USB cable.
Is this a firmware or hardware issue?
