You obviously have never used one...
For installing on in a reprap you need to install the appropriate standard Arduino library u8glib

I don't want it installed in a printer. I want to use it standalone. I installed the u8glib library for arduino. The examples included with that library have 40-50 different constructors for a bunbch of different displays but none of them work with this particular display.
I am trying to see if someone has one working outside the 3d printer environment.

The graphic controller always requires an external controller. You don't need an Arduino Mega/RAMPS combo for it, maybe an arduino nano will do.
Not sure if an SPI interface is required nor if the Nano has one...
For graphic symbols you'd like to have lots of memory, maybe a SD-card slot is a good way to extend the onchip memory.

The RRD smart controller uses a ST7920 display in SPI mode, so look for an example using that. The ST7920 has some quirks, the CS line is active high and the SPI bus can not be shared, so you might need to use software SPI.
Otherwise, printer firmware use the standard u8glib software.

I suggest you look on the Arduino forum for more help.

Check this thread for clarity about spi addresses.

The schematic for the connector that connects the LCD display to the ramps board is distorted at [reprap.org]
EXP2 and AUX-3 have text that overlaps each other and are unreadable
Can anyone provide a readable schematic or provide the pin descriptions?

The u8g driver for the display is U8GLIB_ST7920_128X64_1X.
The SPI address is whatever pin you connect the CS line to.
The schematics for the board is a joke. The pins on the connectors are backwards from what is on schematics. As a results, a lot of boards have the connectors put on backwards for what they need to be.
SCK is EXT1 pin 5
MOSI is EXT1 pin 3
CS is EXT1 pin 4
Probably best to find the datasheet for the display itself and trace out the display pin to the EXT1 header pin.

Thanks for the information on the pin assignments.
I made some progress last night. I installed the Marlin software and the display works. That means all the HW and Connections are okay.
In order to get the display working without the Marlin software, I installed the Hello World example from the u8glib Examples directory. Haven't got that working yet so it it is something in the configuration.
The current constructor is the default U8GLIB_ST7920_128X64_1X which is U8GLIB_ST7920_128X64_1X u8g(18, 16, 17); // SPI Com: SCK = en = 18, MOSI = rw = 16, CS = di = 17
Since it isn't working, I suspect the default pin assignments are incorrect for the mega 2560 & RAMPS board with the special adapter.
Trying to work out what that should be now..

The list of constructors for different displays is exactly the same in those two examples, and I suspect they would be the same in all the examples. There are 66 of them and my file compare utility says they are identical.
Yesterday, I spent about an hour and a half compiling and uploading each and every one of the 66 available constructors (some of which don't actually compile). I know that was dumb and a brute force way of doing things, but it confirms that something needs to be tweaked to get this to work. The standard constructors just don't cut it.

Thanks. Please be aware of my configuration:
Arduino Mega 2560
RAMPS 1.4
RepRapDiscount Full Graphic Smart Controller
RAMPS to Display connector (with 2 flat 10-pin ribbon cables)
Win 10 PC
Arduino 1.6.9
Attached is a picture of it working with the Marlin software installed.

resurrecting old thread... but someone might be interested
I've written a simple RepRapDiscount Full Graphic Smart Controller tester
It an independent arduino sketch and also shows how you can use each part of the display/buttons/encoder/buzzer/SD card reader

And I just found the issue I was having with an adapter for that display to be used with the Duet controller.
What was the issue? Are you going to publish details of your adapter?
The way I would make an adapter is to use a 74HCT08 chip to shift the clock, data and CS signals to 5V levels and gate the clock with CS, as we do on the Duet Maestro. It could plug into both the CONN_SD connector and the SPI daughter board connector, which are conveniently close to each other.

I'm sorry, I hadn't noticed that post was 3 years old.
We do get interest in supporting 12864 displays on the main Duet forum occasionally (https://forum.duet3d.com/), and support code in RRF has been written for 12864 displays because of the Maestro. So it might be worth resurrecting this project.

Cool.
I've actually got a few of the 2004 controllers that I'd like to be able to use with an Arduino for non-printer functions. I was going to pull marlin source code apart to see how it uses it.
