Hello, after attempting several peoples code for driving a Hitachi HD44780 based LCD I am confused.  I happen to be using a Optrex DMC16106A, which is a 16x1 display.  I have this connected via PortB (data) and PortD (ctrl) on a 18F452 Microchip processor.  The processor works fine as I can write simple routines to blink LEDs and everything works fine.  When I attempt to initialize the LCD and write a few characters, the display lights every pixel in every character position.  I know I can doing something, because without the code the display remains totally dark.  I have tried assembly routines as well as C routines all with no luck.  I am using the C18 C compiler and MPLAB 6.0 with no luck. I have even tried using their XLCD libraries to start from scratch again nothing.  Does anyone have any routines that work with the 18FXXX?  I would love some recommendations.  Thanks    Russ Larson</BLOCKQUOTE>
