Hey guys. New member and new Arduino user here. I've been seeing the same issues as Argo. I also have an LCD-00710 screen from Sparkfun. It was garbled just as Argo said. I've tried editing the .cpp file with the "nop\n\t" fix that Argo did as well as add the code that mem posted.
Both of these do in fact clear up the screen a bit, but it's still nothing close to what the pic in the tutorial shows.
Let me know what you guys think I should do. Thanks!
