check the HT44780 datasheet.set the "s/c" bit when wtire the "Cursor or display shift" instruction, and the "I/D" of the "entry mode set" instruction,you will get something!
Good lucky!

Although your display area is 16 characters by 2 Lines, the display memory area is much larger than that. Actually the memory is integrated into the controller itself. So if you dump in more characters than 16 you will end up filling display memory area which are not visible. Now using the display+cursor shift you can have a scrolling effect with minimum effort and software headroom.
