If I define a custom character that uses the lowest (8th) pixel row also, this row is never displayed, although the HD44780 datasheet says this: The 8th line is the cursor position and its display is formed by a logical OR with the cursor. Maintain the 8th line data, corresponding to the cursor display position, at 0 as the curs
