Thank you Paul and Henrik, for trying to help.

Henrik, I tried the CMCON = 7 command, but it generated a syntax error and wouldnt compile. I searched the web for similar topics, and it was suggested to use CMCON0 = 0, and that compiled without any error. However, the LCD still doesnt work.

In my search, I found this thread http://www.picbasic.co.uk/forum/arch...hp/t-4896.html , which mentions a patch for PBP, which fixes 16F688 register issues. I wonder if thats what I need to do?

Here is my current program, which only produces a line of black boxes on the LCD. The LED does blink, as expected....


CMCON0 = 7 'Disable both comparators
ANSEL = 0 ' Set all analog pins to digital

' Set LCD Enable port
DEFINE LCD_EREG PORTC

' Set LCD Enable bit
DEFINE LCD_EBIT 0

LED VAR PORTC.1 ' Pin-9 on 16F688

Pause 500 ' Wait for LCD to startup

mainloop:
Lcdout $fe, 1 ' Clear LCD screen
Lcdout "Hello" ' Display Hello

high LED

Pause 500 ' Wait .5 second

Lcdout $fe, 1 ' Clear LCD screen
Lcdout "World"

LOW led

Pause 500 ' Wait .5 second

Goto mainloop ' Do it forever

End


Thanks for any other further help or ideas.

Bill
