Can't I just connect the output ports OB0-OB3 to a 4 to 16 decoder
and use the first 8 outputs to select the first 8 segments in a led, and the next ones to select the other 6 segments?
Also, can you tell me where exactly do i have to connect the scan line to select the first 8 segments?
Why do I have to use 12 scan lines to select 6 displays?
I thought I would have to connect only the cathode pin from a digit
to the output of a 3to 8 decoder (the inputs are SL0,SL1,SL2) in order to select it.
