The microcontroller in Section 9.3 receives decimal digits (0 to 9) encoded as ASCII characters on its serial port. As each digit arrives, it has to be displayed on a 7-segment display unit connected to parallel Port A. Show the connections needed to accomplish this function. Label the segments of the display unit as indicated in Figure A.33. Write a C-language program to perform the required task. Use polling to detect the arrival of each ASCII character.
