I am working on my first LCD project. Its a 4 X 16 44780 controlled LCD.

In the PBP manual for LCDOUT, two schematics are presented. One uses four data lines, the other eight. What I don't understand is why I would use eight when it appears I can use four.

BTW, I am using a 16F886, if that makes any difference.

Would someone be so kind as to explain this to me? I have searched the forum, but can't seem to find anything on this, and the PBP manual doesn't explain why either.

Thanks,

Andy
