7-segment display question

  1. Jan 17, 2008 #1
    how can i put two 7-segment displays for a counter 0-15??? after 9 there are two digits and i have to use a second 7-segment display to display "1" and the first one displays 0,1,2,3,4,5 as the number becomes 10,11,12,13,14,15 where these aren't BCD numbers...any help

    Are you designing your own logic, or making something on a breadboard with chips? What kind of chips do you have available? If the data is not in BCD format, is it just plain binary?

    You've given us nowhere near enough information for us to be able to help you.

    it's a ripple counter 7493 counts up/down(using XOR gates)from 0 to 15 ...i drew a truth table and i think i got the solution now
