I can not find how to get a negative V to run the 12864a LCD

So far I can compile and load great, but have a completely blank screen
Btw it's a white on black

You do not get the negative voltage for the LCD from the Mega2560. Many Graphical LCDs provide a negative voltage supply, typically on pin 18. Otherwise you will have to generate it yourself with some external components.

Thanks!
Now that I go back and look at the wiring diagram it's pretty clear.
