1. Write an 8051C - program to implement a decimal counter which counts from 0 to 99 using two 7-segments. 2. By using a switch, change the decimal counter to hexadecimal counter from 00 to FF when switch is ON and remain as decimal counter when OFF. 3. Introduce another switch to make the 7-segments counting up when switch is ON and counting down when switch is OFF. Prepare the complete report with C source code and simulator screenshot. 7-segment module (Common Anode) in Proteus: 7SEG-MPX1-CA
