hi.I have made a fibonacci series generator.now theres a last problem i am stuck at i.e  ive used two 4 bit adders to add the two 8 bit numbers.i mean one adder adds the first 4 bits and the other adds the next for bits with carry coming in from the first adder.now the problem is that i want to display this on 7 segment displays.so far ive worked with only one 7 segmet display to display numbers between 0 to 9.ive never used two segments to display 0 to 99 nos but i want to display the series till 99 so how can i connect two 7 segement displays to make this happen?e.g if i add 00000001(1) to 01000000(64), the answer is 01000001 which is 65.. now how can i display 65 on two 7 segment displays?6 on one display and 5 on other display and consequently all numbers between 0 and 99
