3. Implement a BCD to seven segment decoder for a common anode seven segment
display. (It means that sending a 0 to a particular segment turns on and sending a 1
turns off the corresponding LED segment of the seven segment display). Use the
variables A,B,C,D for the BCD inputs with 'A' as MSB. Use only 2-4 decoders and
OR gates to implement the code converter. Don't use any other gates and/or
components
Draw the complete working schematic for the interface of PIC microcontroller with a single digit seven segment display so that the following pins are connected to the digits of the 7 segment display as follows: RE0 connected to a, RE1 for b, RE2 for c, RD0 for d, RD1 for e, RD2 for f, RD3 for g, RD4 for decimal point. Also show a temperature sensor connected to RA0 for reading the analog input. Write a short program to initialize the corresponding ports and show the character ‘A’ followed by the character ‘b’ with a 1 second delay in a continuous loop. Clearly show how the patterns for the characters are derived and used for the program in a neat table.
OBTAIN THE TRUTH TABLE OF THE FUNCTIONS REQUIRED TO ACTIVATE THE COMMON ANODE 7-SEGMENT DISPLAY THROUGH THE 7-SEGMENT BCD DECODER; ACCORDING TO THE SIGNAL SENT BY THE LEVEL SENSORS:
