This 16 character x 2 line LCD packs 32 characters into an outline smaller than that of most two-line displays. This unit uses the HD44780 interface found on most parallel character displays and operates without a backlight.
The DDRAM address 0x00 corresponds to the first character of the top line, address 0x0F corresponds to the last character of the top line, address 0x40 corresponds to the first character of the second line, and address 0x4F corresponds to the last character of the second line.
