Actually, I don't know very well how to program an 8x8 matrix with 2 74HC595 and I wanted to know if I can help myself because I don't have the clear idea ... 
since my teacher just sent us to do several types of circuits, without teaching us how to do it, the one that has become complicated for me is this, that's why I would like help, since I have the circuit I would just like somebody's help with the code to understand how the process of everything is and how it works.
ok, you don't know how to program. can you explain how the circuit you posted works?

What you have to do is show my full name, but I honestly don't know how to program it that way, so I ask for help
Project 7.- 8x8 led matrix with shift register
In this practice, and execute the programming in such a way that a text message can be displayed in the 8x8 led matrix (in this case, its full name).
and they gave me the images that I uploaded to this post
