    I think it's going to be difficult to hold 40 custom characters, since the CGRAM in a 44780 based LCD only has room for 8 custom characters.

    Also keep in mind that the CGRAM is volatile and the 8 characters must be loaded each time the LCD is powered on. One trick you can use is to redefine characters on the fly, however you cannot have more than 8 unique custom characters at any one time. Take care.
