Interfacing 8051 Microcontroller with 7 Segment Display

As we are showing Proteus simulation, below are the requirements for the coding and simulation.

1. Keil uVision: There are lots of products from Keil. This will require a c51 compiler. You can download that software from here.

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

Along with the hardware, you will require flash magic software to upload the code onto your hardware. Remember flash magic is developed by NXP, so you cannot upload any 8051 family microcontrollers through this software. So you can only upload using a Philips-based controller.

Components Required

Here in our demo video we are using Proteus simulation but definitely for your hardware you will require these components for this project.

8051 Development board: It is better if you have this board so that you can easily upload the code yourself.

Seven Segment Display: There are two types of 7-segment displays; one is Common Anode and other is Common Cathode. In our Proteus simulation ,we are using a Common Anode display.

USB to UART converter: This is a 9-Pin D type male connecter for RS232 O/p.

Some Jumper Wires

Source Code

You can get the source code from our GitHub Link.

Working Principle and Video

You need to pass the correct hex code to generate numbers in 7-segment display. You can watch the video of this project working principle and code I've explained there.
