Well I changed the LCD_DATAUS n from 75 to 150 and the led fired up on PORTA.5, still no text on the LCD though.

I would not think DATUS would cause the LED not to work...
Have you adjusted the contrast POT after connecting the back light? Maybe it is just washed out ?

Hi mackrackit,
Yes, I've even disconnected the back light but can't see any text now, it hasn't reappeared.Have you adjusted the contrast POT after connecting the back light? Maybe it is just washed out ?

I've cracked it...........!!!.....Yippeee.
PIN 5 onto LCD from PIC loose R/W.
Henrik, mackrackit, really sorry to have caused a problem.
The display looks great, bright but not too bright and the text is as clear as clear.

I don't think it'll be my last either...
Really pleased it's going though.
So a good place to start and get a grip / understanding of LCD display characters would be that link you posted earlier:
Interfacing an LCD with a project opens up so many possibilities, be it just instructions right through to displaying live information. I suspect it's not going to be easy but I'd like to get a grip on LCD's: They're seriously...

Yes, that link will show you how to do custom characters.
You will also want to look in the manual about how to place a normal character anyplace on the display along with different things that can be done with the cursor.
