I think you'll find that the LCD clear command takes a long time to=20
perform, so make sure you add a delay in there too.

Take another look at the LCD data sheet as it will specify how long each=20
command takes to complete.

You *have to* wait after a few of those commands as the LCD will ignore=20
you while it is busy.
