25 Oct 06. LCD readout problems.  Incorrect data When you print to the LCD, what was already in the display is written over.  If the data takes up less space than what was already on display, those items that are not written over will remain visible.  Try the following program segment to see what happen. LCDOUT $FE, $80,"First thing written" LCDOUT $FE, $80,"Second" The result will be Secondng written To clear the remaining part of the message, print spaces to cover the first message A second line that was LCDOUT $FE, $80,"Second                    " would fix the problem.
