Pros of 4bit comms: only 7 I/O lines needed to interface. Cons of 4bit comms: slightly more code required to drive the display Pros and cons of 8bit comms being directly the opposite of 4bit, with 8bit needing 13 I/Os Regards, Chun Chiek ----- Original Message ----- From: "Tal" To: Sent: Saturday, May 10, 2003 6:31 PM Subject: [PIC]: LCD 4bit or 7bit? > Hi > > Can you explain what are the differences between the 4bit & 7bit regarding > LCD displays? > are they any differences at all? any limitations? when I should use 4bit or > 7bit? > > Regards > > Tal > > "I have not failed.
