CrossRoads, is there a special reason why the LED cube that we've discussed here uses the cathodes as columns (64 cathode columns) and the anodes as planes (8 anode planes) and not the other way around? Many other cubes that I've seen use anode columns and cathode planes and it seems to be more practical that way because the anodes are 2-3 mm longer, which compensates for the fact that the LED heads are taller than wide, so the horizontal and vertical distances between the LEDs could be longer and still equal if we used anode columns and cathode planes. Is it possible to do this reversing of anode/cathode roles? If yes, how?
Thanks,
Andras
