I'm assuming you did not change much if anything in Michael Karas's main
that\ufffds included with the gLCD files off of 8052.com. So being that\ufffds the
case now its time for deep troubleshooting. Believe it or not you have
just begun so either get coffee or a beer and snuggle up to your work
bench.

Zip up your modified glcd directory preserving the subdirectory structure
and email it to me at newmanrf@...

I will wire up a display to a LPC this weekend. See if you can document
your lcd wiring and I will wire mine up the same way.

Do you have a scope?
  If Yes-> Do you see activity on your data and clock lines.

One quick idea-> Add large delays between your writes to the display. This
controller is slow and you might be speaking to it too quickly especially
after you command it to reset/initialize. I really wish there was a busy
pin or way to query the display and ask if its ready but there is not so
this is something we just have to live with.

Let us know if the delays work and if not zip up your stuff and send it.
