Which side is the top of a NHD-0220CW-AY3? The only indication of orientation I can find is the picture on the product page. I am using one right now and the bottom of the text is facing the 20 pin connector which is opposite of what is shown on the website. (See attached photo)

  Hi psullivan,
  That display does like flipped upside down, and it shouldn't be.
  
  I was wondering if you could possibly also post a picture of the back of that display, and your code.

  Picture of back attached. Not sure if I can post my code, I will have to check. Is there even a way to flip the display through software?

  Ok, I was able to replicate this issue thanks to Paul.
  
  There is a command to let you flip the direction and orientation of the characters.
  
  Check to see if you are sending a command(0x05) in your initialization after sending a (0x2A), that sets the screen Upside down.
  
  If you want a quick fix, try adding

    command(0x2A);
    command(0x06);
    command(0x28);

  at the end of the initialization, that should do it.
