Hi all, this is my first post,my name is Francisco Javier; I am from Menorca, spain, so sorry if my english sounds bad.
I am really new to arduino, but I got to run a LCD like this one.
Maybe I am telling a foolishness, but I have seen in the code you are using the pins 11 and 12 as data and not for Enable and RS. I am wrong or is it??
(12,11,5,4,3,2,1) instead of (5,4,3,2,1,12,11)
