Bene
Welcome back. how was thailand (lucky b...benedikt 
) (btw i've sent you an sms)
remeber that the max7313 is very different from the 7219. the 7219 can only dim a whole block of leds at the time while the 7313 can dim each LED individually. In order for the 7219 to dim each led individually it's going to be tricky (especially for large displays)
so mr benefit your code will be much simpler, if you come to milan i'll write the code for you
