Actually, I'm not doing anything so far, just in future, I want to make a small RGB display, 192 X 12 pixels, using these LEDs. My experience with 64x8 LED displays, based on 4 x MAX7219 was not so good, because this "serial" method of needing to update everything at each time, required complete re-send of data to display, which was quite lagging, and won't allow to do some cool animation or smooth scrolling.
