Hi B_B
Ok, I'm sold
These LCD's look like great fun and a really useful interface.
When my first LED came on, that was brilliant. When my seven segment display /
driver lit up and counted up to nine that was cool.
These look in a different league, can't wait.

That one doesn't look like it's got a backlight. One with a backlight would be sexier...
Here in the US, I find these to be a good deal for $10USD.

Don't know about UK vendors.

Interrupt on change (interrupt when the state of a pin changes)
Again this is a snippet from another chip (16F873A) but it will give you something to start with.
Code:ON INTERRUPT GOTO MYINT INTCON = %10010000 'PORTB.0 CHANGE DISABLE MYINT: IF PORTB.0 = 1 THEN ' DO SOMETHING ELSE 'DO SOMETHING ELSE ENDIF INTCON.1 = 0 RESUME ENABLE 'THE ABOVE WILL ALSO DEBOUNCE THE SWITCH

Cheers mackrackit,
I made a little table up that other newbies who are maybe following this thread might find useful. It hinges on what you said the other day about setting the prescaler (TMR0) and using that with (I = I +1) to set up a delay of your choosing.
Didn't quite come out as planned and every time I edit it the changes I make it just resets.BIT TMR0 Time_u_secs HZ
000 1:2 512 976
001 1:4 1024 488
010 1:8 2048 244
011 1:16 4096 122
100 1:32 8192 61
101 1:64 16384 30.5
110 1:128 32768 15.2
111 1:256 65536 7.6
Still, I'm sure you get the drift (might be worth checking my figures as well though).
Any thoughts on that LCD?

I've just had a thought.
It's probably dangerous for me to offer advice right now, no matter how well intensioned. As some of my conclusions maybe a little off the mark.

Most of mine are, does not stop me...
In the LCD product spec page (15/17) it says:LCD... Back-light would be nice but I did not see very many options from your supplier. So that is why I was looking at one with four lines.
So maybe it does have a backlight?(8) In particular do not forcibly bend the I/O cable or the backlight cable.
That's for the display we were looking at:
