i sampled them, but i don't have them yet.
about this page
http://www.arduino.cc/playground/Main/LedControl
it's in my bookmarks, but this library can control a maximum of 8 display's. is it possbile to run the software twice so it can control 2 rows of max7221?
nr. 1 does the upper 8 panels and nr 2 does the lower 8 panels.
about the sampels, i know almost certain i'm gonna do something in electronics, so i'l let my future boss know i need to buy 10.000 max7221's
