first let me clear your question..there is no 6 SSD . SSD is seven segment display. you can built A circuit with 5 volt supply and if u know binary code in the scene that is more than enough to write the code. you need 470ohm of pull up array to connect to the seven segment.use 8051 any port i think below (...)

before using lm35 & adc interface, simply send a fixed value, lets say "52" to the display. for this make a lookup table for each digit 0-to-9 having it's corresponding seven segemnt code. The 2 displays will run in multplexed mode. after you get the value then take the adc & lm35 and read the value & then transmit it to display.

Do something similar to:
2'b00 : out <= out;
2'b01 : out <= 1'b0;
2'b10 : out <= 1'b1;
2'b11 : out <= ~out;
so that you can use the bits to control the 7 segment display or you can also use a seven segment decoder =)

Here's pseudocode for what you want:
for each digit
select digit i by grounding common cathode
apply seven-segment drive for this digit
This code will need to sequence through the digits at least 40Hz or faster.
However, don't scan too fast since that will reduce the apparent LED brightness.
