I am building a simple 3-bit adder that will add two 3-bit numbers together. The result is then display in decimal format onto either one or two 7 segment displays. The highest number that will be displayed is 14. I already have the adder logic setup and all is good as far as that goes. I also have the logic to display the "1" on the second 7 segment display for when the result is 10 or above. My problem now is how do I decode the the 4-bit binary number to display it? I cannot use a GAL or and other PLD. I thought about using a BCD decoder, but ran into problems digits above 9. I cannot have letters being displayed. My other options are using a 3:8 DeMux(s) somehow, or implemented the logic using gates.
Can anyone offer some advice?
