This Analog data is read and the number 1-5 is shown on the 7 segment common anode display with 7447, but I can’t set this number for analog value because I can’t show analog values or output I wrote this code in MPLAB X IDE.

my aim in this project is to print the number between 0-5 on the 7 segment common anode display according to the analog data between 0-1023, but I could not solve this problem.
