I have been trying to get the HD44780 LCD to work with the 18F452 at = 20Mhz with the MPLAB C18. Has anyone had any luck? I have made the = necessary changes in the MPLAB-CXX Reference Guide example (the example = for 4MHz - although it does not say - plus the example had a function = CloseXLCD which does not exist).
