GPIO:  HD44780 chip from old Fax Machine.

How do I get this to display messages, text, etc; through GPIO?  I have seen others do it before but they never state or tell how they do it.

 

I want to know if this is possible to do and how difficult it is to get the software for it.

 

This is my screen:

This is the chip:

How do I wire them togther (they are already on PCB togther)?  How do I wire them to GPIO?

 

I can work off schematics and can follow very basic instructions (but can not compile software).

    Here is a picture of the whole board.
