connect 6 leds together
@xfilesb ,
I guess that you are against using the 7447 decoder because of its power consumption. In such a case you can always get the CMOS counterpart. There are at least four types available. If you, however, are not happy with any decoder IC at all, there are still two possibilities for you. As suggested above, you can use serial In parallel OUT registers to handle your display, or you can build a BCD to 7-segment decoder using some silicon diodes and some transistors. This way your six digit display would use just seven pins of one uC port. It is the simplest solution I know, but not the most elegant one.
The choice is yours.
