ABSTRACT:
A single-line 16 character display is driven using a display driver designed to drive two independent 8 character single-line displays. Conceptually, the 16 character display is treated as the two independent 8 character displays placed side by side. The message for display is placed in a first area of driver memory corresponding to the first 8 character display. A truncated version of the same message for display, with an offset at the beginning equal to the number of characters in the first display line, is stored in a second area of driver memory corresponding to the second 8 character display line. When the message and the truncated version thereof are simultaneously displayed, an observer views a single, coherent 16 character single line display. If the message is greater than 16 characters, the driver scrolls both the message for display and the truncated version thereof, creating a single scrolled message from the point of view of the observer.
