try this
define lcd_bits 4
define lcd_lines 4
PAUSE 500
start:
lcdout $FE,$80,"LINE 1 "
lcdout $FE,$C0,"LINE 2 "
lcdout $FE,$94,"LINE 3 "
lcdout $FE,$D4,"LINE 4 "
pause 1000
goto start:
The only thing I dont see is a varable resistor for contrast adjustment on V0.
You have it tied to +5v, the voltage may be to high that is why you are only seeing squares insted of text.
Hope it helps Sphere...

Datasheet ?
Hi, coyote
May be you have it, ... but if not :

Note also Vee must be set BETWEEN +5v and GND ... with a pot !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

I needed the pot between Vee and Gnd. It measures at 455R. I was using a 10K pot according to the schematic set at 5K, but never turned it down to such a low value before thinking I must have something wrong. Another thread had a working Optrex with Vee at 5+. Duh . . .
