The user may choose the mode that is most appropriate for the application.Overwrite Mode:******************************************************************************************* from left to right, if it is at the end of the Line, it moves to the beginning of the other line. Characters are displayed at the Current cursor position, overwriting what is originally there, the cursor is then moved to the next position.Vertical Scroll Mode:If the cursor is at the upper line it behaves like the overwrite mode. When it is at the end of the lower line, the next character would scroll the content of the lower line to the upper line, the lower line is cleared and the cursor is moved to the beginning of the lower line.Horizontal Scroll Mode:In this mode the cursor stays in what ever line it is at, unless changed by cursor Movement commands. When the cursor is not at the end of the line, the input Character is displayed at current cursor position, the cursor is then moved right. Once at the end of the line, subsequent character input would scroll the current Line left one position, and the new character is displayed at the end position. There is also a command, ESC W, to set display window in this mode. The effective display line would be limited within the window as defined by the command.String Mode:This mode is perhaps the simplest used. The two display lines are treated independently. Only two commands, ESC Q A and ESC Q B, are needed. ESC Q A followed by a string on the upper line, left aligned. A CR (0DH) character terminates the command. If the string is less than twenty characters in length, the rest of display line is padded with plank. ESC Q B does the same for the lower display line. The only other commands active in this mode are CLR and CAN. CLR would clear the display and change the LCD into overwrite mode. CAN clears the last line that was changed and change the LCD into overwrite mode. The initialization command, ESC @, has no effect in this mode.11.
