Lecture 23: Assembly language program to interface seven segment display to 8051|display interfacing

In this video assembly language to interface one seven segment display and also multiplex seven segment display is explained.
For the theory of 8051 and PIC microcontroller refer the following blog:

This Lecture would go nicely with the 4x4 matrix keypad lecture 29, that way you would actually have an input and a two HEX digit output, using the 8051 micro controller.I think you would have to store the first value entered and shitf it over when a second value is detected. Then when a third value is detected clear the fist value out or back to zero.

This is a nice tutorial on multiplexing 7 segment displays. However, you only discuses one possible 7 segment display table for the common cathode. There are many different ways of reading and writing the 7 segment display codes. I am not trying to confuse anyone, just providing the information, that there are several ways of writing a truth table for a 7 segment display and it also depends on how you wire your segments and of course there are just as many different tables for common anode displays as well.

Hi, I have few question on 7 segment display and i am making one project based on it and i'm stuck in that project, can you please help me Jeff Nay

Mam can you explain how we can use serial communication in 7 segement diaplay if i press my pc keyboard numbers then it will display on SSD ?

[@shahzebhusainshaikh4767]

Can you please provide me the ASM PROGRAM for counting from 000 to 999 on multiplexed SSD using the same microcontroller?

[@johnbilla1416]

Is the coding same for Msp430 microcontroller

[@shazneyhamili2733]

How about in assembly code for common anode?

Hi, I'm Taral Mehta, I am trying to make one small project for my knowledge. I want some help from your side, I want to use an 8051 microcontroller with 2x seven segment display. I want to add three modes in that display by coding ,please help me in this part , I am stuck in it.

[@taralmehta593]

Hi, I'm trying to make a code for 7 segment display with three modes(using switch)...can you please help me in that case???

[@jeffnay6502]

Were you able to work out your problem? I am interested in what you were trying to do. I am looking to display 2 7 segment displays using a keypad.
