I read the small tutorial on this link:
http://www.imagesco.com/articles/lcd/05.html

THE book I am reading use terminology N24400 while the compiler I use uses: PortB.0,0, thus in the last I did not declare anything and it compiles

also I have a 16x2 lcd. I hooked up ground pin and vcc. The screen lights up, but I tried all the pins on the screen running from pin 6 of the Pic16f84 but I am not seeing anything
Is there a delay?
I am not sure is there is only one wire or more is needed
thanks
