The pic/sed system is intended to be a stand alone system. The rs232 comm was done only for debugging purposes. But it's very easy to convert the rs232 routines to standalone routines George Chatzigeorgiou ----- Original Message ----- From: "Scott Dattalo" To: Sent: Saturday, February 10, 2001 8:51 PM Subject: Re: Graphic lcd project > On Sat, 10 Feb 2001, George Chatzigeorgiou wrote: > > > A long time ago i promised some code about a graphic LCD.
