PeterPan321:
I probably don't have the best HD44780 library. Something written by "Francisco Malpartida". But I'm using it because of all the HD44780 libraries out there, this was the first one where I could get the LCD to do anything with any of their examples.
As for myself, I had no problem with the LiquidCrystal library included with the Arduino software. I could write to the display just fine, and even get custom characters. I used it in this project here:Two-button clock - Exhibition / Gallery - Arduino Forum
Did you try the LiquidCrystal library? Did you have problems with it? If so, what problems?
