Since a couple weeks I am trying to get my LCD working (a HD44780 compatible 4x40). I don't know what I do wrong. I have wired it up correctly, but when I use (Enchanted) Liquid Crystal, it doesn't work. Not even with one enable-line (the normal library)...
I can adjust the contrast, and the backlight en power does work. With the new arduino IDE (1.0.3) I get a lot of errors that BYTE is not longer supported and that I have to use Serial.write() instead. I think I'm not the only one with this problem. Googling didn't help so far, so I ask you.
Do we/I need to rewrite the (Enchanted)Liquid Crystal library? Or where could I go wrong?
