Two Digit 7 Segment Display Digital Counter Using 8051 Proteus

This video is all about Proteus simulation of two digit seven segment interfacing with 8051 micro-controller.

Generally we have used single digit seven segment display for counting, but if we want to display numbers from 00 to 99 then two digit seven segment display is used. It consist of two select lines 1&2.

When we want to display number of first digit then pin 1 is made logical high from micro-controller 8051 & for displaying second number pin 2 is made logical high and then data is sent from 8051 to seven segment display to display out the required number.

Port 2 of micro controller 8051 is interfaced with pin A B C D E F G DP of seven segment display unit.

Select lines of to digit seven segment display is connected to Port 3 of 8051 micro-controller.

Concept:-
1. When start button is pressed counting starts from 00 to 99.
2. When stop button is pressed counting is paused and that number is displayed continuously on seven segment display unit.

Note:
There are two types of seven segment display :-
1. Common Anode
2. Common Cathode
In this Proteus simulation common anode type of seven segment display is used.

Programming is done using Keil Micro Vision 5 and code is given below:

Thanks god! I couldn't do this, but you can. This code is my lab and now I figured out how to do it👍
