Lcd003 light on

johnproko

Hello everyone and Merry Christmas!

I have a BS2 with the board, and except of the BoeBot im totally a rookie.
My problem is an Lcd003. Does anyone have some examples?
The one that i found at parallax website is just the basics. I read that it has a light but cannot find anywhere the demo code. To be honest i pulled the ground cable and the lcd started blinking, its fine though.
I also would like to ask what are all those pins at the right?
Probably im way over my head.
Thank you in advance.

p.s.
pics are from http://www.robot-electronics.co.uk/htm/Lcd03tech.htm
and the basic code im using for the screen is:

' {$STAMP BS2}
' {$PBASIC 2.5}

lcd PIN 6

lcdbaud CON 84

lcdcls CON $0C
lcdlighton CON $11
lcdlightoff CON $15
lcdon CON $16

HIGH 6
PAUSE 100

ok the light is on but not constantly. if i mess the wires on the rear (vss, vdd) the light open but resets the program. i now have a ping ultra distance sensor and the lcd is showing the distance.

Alas, the board you have is different from the display board that Parallax sells and we can't help you with it. Just glancing at the documentation for both displays, it's clear that many of the command codes are different. You'll just have to go through both sets of documentation and mark them up with the differences, then modify all the sample programs for your display.

Thank you very much for your information. I though it was a parallax item because i found it in a box with other parallax items. Again i thank you! Happy New Year!
