If you have a single segment turned on at once, and mux through all the digits with just one segment turned on and the illuminating current sunk through one resistor, there's really no disadvantage at all, Yes, but that's an awful lot of "ifs" - none of which is even remotely hinted at on the page in question: http://www.iguanalabs.com/7segment.htm Also, the OP is having trouble with the very basic concept of common-anode vs common-cathode - so I hardly think he's going to be in a position to consider the merits of multiplexing the segments within each digit and the digits of a multi-digit display...! :-0 |
