I am trying to working on a NHD-0216CW-AG3 with an ATMEGA2560.   I tried first with i2c, everything seem to work fine, except that the datasheet states that in i2c mode, it doesn't support 5V VCC.

So I tried to use 6800 4 bit Parallel mode, and I got all the display mirrored, also the display direction was inversed, when I do lcd.rightToleft(), I got display starts from left to right.  Any one has any experience on how to make it work with LiquidCrytal library?
