Dot Matrix LED Display Interfacing With 8051 Microcontroller

About: We are a team of passionate engineers who works on embedded system and IoT. Here through this page you will come to know about embedded system from scratch to the latest technology based controller. We will ...

In this project we are going to interface one dot matrix LED display with 8051 microcontroller. Here we will show simulation in proteus, you can apply same thing in your hardware. So here we will first print one character let's say 'A' in this display then we will make it scroll in that display.

This is very interesting project. I think you have seen lot of application of these type of matrix display in real world. So here using 8051 we will make one prototype of this display project.

Step 1: Software Used :

As we are showing proteus simulation so FOR CODING AND SIMULATION YOU REQUIRED:

1 Keil uvision: Their are lots of product from keil. so you will be required c51 compiler. You can download that software from here

2 Proteus Software for simulation: This is the software to show simulation. You will get lot of information to download this software.

If you are doing it in hardware then you would require one software that is flash magic to upload the code in your hardware. Remember flash magic is developed by NXP. So you can not upload all 8051 family microcontroler through this software. So Philips based controller only you can upload.

Step 2: Components Used:

Here in our demo video we are using proteus simulation but definitely if you are doing it in your hardware you will be required these components for this project:

8051 Development board: So if you have this board it will be better so that you can easily upload the code by yourself.

8*8 Dot Matrix LED display: As we are using 8*8 display so there are 64 LEDs in one single LED display

USB to UART converter: This is 9 Pin D type male Connector For RS232 O/p

Some Jumper Wires

Step 3: Code

You can download the source code from here

Step 4: Circuit Diagram

Step 5: Project Explanation:

The whole Project Description is given in above video
