how to display adc on seven segment display

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.

adc with output given to 7segment display

two driver ics 4511 are attached to seven segment display so their output are applied to port 2
i hav defined values 00000000b to 10011001b
in lookup table so am storing adc's data in accumulator and used accumulator value as a pointer to lookup table value is it right
if not help me by coding

but cd4511 is also working well i hav tested the code its fyn but the only problem is wid intensity of led segments i hav used 10k resistors as pull ups but my teacher told that these pull ups r not right so now m going to use 220 ohm will it work
anyways thanx all u guys 4 ur help
