Interesting result on a 16F688 with ADC and LCD

[andywpg]

OK I now have something on LCD but its jibberish. I moved chip and lcd to breadboard for time being, PORTC 0-3 is now starting bits, RS is C.4 and E is C.5, nothing else is hooked up except LCD. I will need to turn on ADC for PORTA 0 & 1 after LCD starts working.

I had trouble without the following two defines (after the ones you already have):

' Set command delay time in us
DEFINE LCD_COMMANDUS 1500
' Set data delay time in us
DEFINE LCD_DATAUS 44

Then try this:

PAUSE 500 ' Wait 0.5sec for LCD to initialize (May need to be one second, depends on your LCD)
DO
    LCDOUT $FE, 1, "This is a Test"
    Pause 1000
    LCDOUT $FE, 1 'clear the screen
    Pause 250 'wait 1/4 second
Loop

No reason the above shouldn't work. Good luck
