convert hex code to 7 seg display

It is almost trivial.
You make a lookup table with ten entries, one for each digit in the range 0-9.
Each entry in the table has a one to turn on the appropriate segments.
Use the digit as an index into the table.
For each digit you want to display, output the contents of the corresponding table entry.

Throw the ADC0804 away, and use a PIC - this can read the analogue input and display directly on the 7 segment displays - you just need to write the software to do it. But all the code you require is in my tutorials.
