I only have to deal with the BCD 8421 Outputs from his build...Inputs into my build for display in a 2-bit 7-seg. So far I can get it to show 10 and upto binary 1111 as expected, but I need to some how shift it so I can read 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15....The first digit has to recirculate some how so I can get it to read 1 on a binary 1011, 2 on a binary 1100, and so on. Would a demultiplexer work???then re-encode it ???
I could just build my own complete project and it would probabaly would work better.
Our instuctor is testing us on cooperation.
Basically I only need to decode BCD 8421 to show 1 through 15 on a 7-seg display.
Digit MSD,LSD 2 bit decimal. This is what I need the display to show. A full 8-bit binary count.

Although it may be just as easy to build one the shows decimal upto 99.
