help with 4 x 20 LCD

its also possible that the default config settings in your pic16f887.inc file don't match your setup

can you blink a led at defined rate correctly ?

I added the address for good measure. No luck. I increased the start up wait time. No luck still. I added a blinking LED and that works - on for half a second, off for 1 second. Stuff highlighted in RED is what was added/changed.

TRISB = %00000000
pause 500
mainloop:   
     Lcdout $fe, 1                                 ' Clear screen   
     Pause 500                                     ' Wait .5 second   
     Lcdout $fe, $80, "Hello"                                ' Display "Hello"  
     PORTB.7 = 1                                      'LED on 
     Pause 500                                     ' Wait .5 second   
     Lcdout $fe, $c0, "World"                 ' Move to line 2  and display "World"  
     PORTB.7 = 0                                      'LED off 
     Pause 500                                     ' Wait .5 second   
Goto mainloop                                    ' Do it forever   
End
