Virtual Serial Port Simulation Proteus
Hello friends, hope you are having fun. In today’s post, we will have a look at Serial Communication with 8051 Microcontroller in Proteus ISIS. In the previous post, we have seen a detailed post on in Proteus ISIS, which was quite a simple tutorial. And I hope if you are new to 8051 Microcontroller then from that post you must have got some idea about C Programming of 8051 Microcontroller. Now, today we are gonna go a little further and will have a look at Serial Communication with 8051 Microcontroller and we will also design the simulation of this project in Proteus ISIS software. 8051 Microcontroller also supports Serial port similar to Arduino and. And the communication protocol is exactly the same as its a Serial Port.

But obviously the syntax is bit different as we are not working in software. So let’s get started with it. Serial Communication with 8051 Microcontroller in Proteus.

Let’s first have a little recall of Serial communication. In serial communication we have two pins which are named as TX and RX. TX pin is used for transmitting data while the RX pin is used for receiving data. So, our microcontroller has these two pins as it supports Serial Communication and these pins are located at Pin no 10 and 11 in AT89C52 Microcontroller, which I am gonna use today. First of all, we will design a Simulation of this project in which there will be 8 LEDs attached to Port 1 and by sending characters through Serial port, we will either turn these LEDs ON or OFF. After designing the Simulation, we will then design the programming code for and will test our result.
- I tried to connect haserver proteus simulation with virtual serial port software. But I couldn't do it. That the telnet client is not responding to the proteus.
- Tutorial: Virtual Serial port using VSPE. (Virtual Serial Port Emulator). We can create any circuit in Proteus ISIS simulation software.
So, let’s get started with Proteus Simulation of with 8051 Microcontroller. Now in the above figure, I have used crystal Oscillator of 16MHz as I did in the previous post LED Blinking Project using 8051 Microcontroller and again the reset is pull Down. Next I have attached Virtual Terminal with TX and RX of 8051 Microcontroller, if you don’t know about Virtual Terminal much then I suggest to read.
Finally, I have attached the 8 LEDs on Port 1 so that we could check whether we are getting correct data or not. Now let’s design the programming code. Programming Code. You can see in the above code that baud rate we have used is 9600and we have used a switch case method for turning ON or OFF Leds. So, now what it will do is when you send 1 on Serial Monitor, it will turn ON the first LED and when you send “a” on Serial Terminal then it will turn OFF the first LED. The same will go on for 8 LEDs.

Character 1,2,3,4,5,6,7,8 will turn ON the LEDs from 1 to 8 respectively. While the character a,b,c,d,e,f,g,h will turn OFF the LEDs from 1 to 8 respectively. For each command it will reply us back a single character which is “k”. So in this way we are doing the two way communication i.e. Sending as well as receiving the serial data. So, now after adding the code, get your hex file and then upload it to your Proteus Simulation and click the RUN button on your Proteus software.
When you start your, all the LEDs will be OFF and the virtual terminal will be open as shown in below figure:. So, now click in the Virtual Terminal and press 1 and the first LED will get ON and you will get k in response as shown in below figure. You can see in the above figure, I have pressed 1 and the first LED goes ON as well as we get a response “k” in the virtual Terminal. So, that’s how we can turn ON or OFF LEDs so in the below figure, I have turned ON all the 8 LEDs. Now you can see in the above figure,all leds are on and the is showing k for 8 times as I have given 8 instructions. You can download the Proteus Simulation along with hex file and the programming code by clicking the below button. So, that’s how we can do Serial communication with 8051 Microcontroller.
Rwaldron / johnny-five. These virtual ports will be used to connect the serial port component from Proteus simulation. It will create two virtual serial.
I don’t think its much difficult but still if you have problems then ask in comments and I will resolve them. That’s all for today and will meet in the next tutorial soon.
