8x2 Lcd

[Darrel Taylor]

The first thing to do is make sure that the display uses an HD44780 controller.
You should see the number on one of the chips if it does.

If it does, then the problem may be due to timing differences.

Try this ...

DEFINE  LCD_LINES  2
DEFINE  LCD_COMMANDUS  5000
DEFINE  LCD_DATAUS   500

PAUSE 3000
LCDOUT $FE,1
PAUSE 2000

LCDOUT $FE,1,"HELLO:",$FE,$C0,"WORLD!"

STOP

And if by chance it works, start reducing the numbers until it stops working, then add a little back in for safety.
