HT1632c_Sure electronics_Green_Led_dot matrix_display

Hello,

Arduino-Community, I hope someone can help me with my project.
I bought a Led-Display from Sure electronics: http://www.sureelectronics.net/goods.php?id=1136

I try to understand how the IC HT1632C works, with this tutorial from Luca Dentella

http://www.lucadentella.it/en/category/ledmatrix_ht1632c/

Luca Dentalla uses a diffrent LED-Display but the prinicple should be the same.

Also I found the libary from westfw

http://forum.arduino.cc/index.php/topic,21819.0.html

but this libary does not work, What is the diffrence between HT1632 and HT1632C?
