That is a good question. I don't know why the 19s and 69s are there. I got the code from the forum http://arduino.cc/forum/index.php/topic,7091.0.html. It was the only example code for GOL with max7219 I could find. I tried to rework it the best I could to make more sense, but that whole section with 19s and 69s i don't understand. I also tried to rework the GOL code on Arduino Playground - DirectDriveLEDMatrix to work with max7219 and the ledcontrol.h library but could not get it working. I'm fairly new to the more complicated part of coding but i'm trying. I would appreciate any tips or any help anyone can offer in doing this.
Much thanks,
Matt
