led matrix scrolling characters

Other Hardware LEDs and Multiplexing
1

I want to make a program for a scrolling text with char and digits.I am reading the LedControl library and i saw the example for the Matrix.
I want to ask that at the example it give the code for each character.Is there a the complete code for all characters? or i should make them as the example one by one?
Probably there is something i did not get.Any help?

Also i see that according the library:
/*

  • Set all 8 Led's in a row to a new state
  • Params:
  • addr address of the display
  • row row which is to be set (0..7)
  • value each bit set to 1 will light up the
  • corresponding Led.
    */
    and at the example he does not scroll the text he light the led to write the word.Isn't that correct? If it is how do we scroll is there any ready library so i do not have to implement a method for MAX7219 led driver.
