Matrix 16x32

Hi all, after searching for information everywhere and buy a book to learn about arduino, I can not find anything about these LED panels. The panel is one-bought Seeedstudio page and it is a demo file, which if it works but after going crazy I do not get the screen changes after activation of an entry and I resign myself to ask you for help to see if I can tell you where to find information, or see some example command tell me that makes me want to get to continue with my project. In this forum I also tried to find information, but not find anything and makes me weird, something bad will do I hope to learn a lot in this forum and sorry if I have broken any rules of the forum.

Greetings to all
