Lcdout question.

[Steve Matson]

It's working. I was making two mistakes. I had the contrast pin three go to a voltage divider. and I was unpluging the lcd and pluging it back in. After I hard wired the contrast pin to gnd, it worked great.
Here is the code I used. You will notice there are some commented stuff that isnt useful. But this works great with the schematic in the book. Thanks for all of your help.

Your initial Pause 100 could stand to be Pause 1000 or sometimes 2000.
The 100 might work with this particular brand of LCD, but generally, most LCDs like a second or two for startup. Might save you some hassle in the future.
