You might have seen a " Hello World! " program code example while learning some programming language. While it is useful for getting familiar with the basics of that language, it also gives you a head start in that environment. If you ever want to learn some new programming language, you might want to Google out a "Hello world!' program code to get started. The code I am about to discuss serves the same purpose for the 8051 microcontroller because it is the most simplest task to perform. Play close attention if you want everything to work properly.

I have already written a brief post on how to use KEIL uVision in which I deliberately left the debugging part out because I wanted to talk about it at a proper time. I think it's now. If you haven't noticed it yet, KEIL uVision is also a debugger and will help you debug many of your codes and programs. The debugging environment of KEIL is very simple to understand and make use of. Today, I will introduce you to it. Ready? UPDATE: You can also click this link for an updated version of this post. READ MORE

The simulators I mentioned in my previous post were strictly for beginners. They just show you the output of the microcontroller so you can learn how everything works. They will accompany you as long as you are dealing with manipulating the data on the ports or registers. Sooner or later, you will be going further and attaching external hardware to the 8051 but that's exactly how we deal with it. So if you're talking about simulating a complete circuit then you actually need PROTEUS for this.

Everyone wants to see some practical results after working hard on a project. Same is the case with 8051 microcontroller. You have probably designed something involving the 8051 and written / compiled a program code for it and you are almost ready to put it to test. I know you can't wait but there is still one essential step before jumping on to the implementation phase and it is called simulation.

Finally you have decided to write your own code for the 8051 microcontroller. It doesn't matter whether you have chosen Assembly or C Language for yourself but what matters now is that you need an environment specially designed for 8051. Basically you are looking out for IDE (Integrated Development Environment) that will help you build and compile programs. While there are many options out there, I prefer KEIL uVision in this regard.

If you are interested in programming then you are definitely familiar with some programming language and probably written few programs or compiled few codes. If you are not, then I strongly insist that you check it out first i-e read the basics of programming. Writing codes for the 8051 microcontroller is not much different. You choose some programming language for yourself and then you start writing codes in the correct environment. That's all it takes.

To use the 8051 microcontroller, you definitely need to program it first for the intended purpose. What does that mean actually? The 8051 itself is just a piece of hardware capable of doing nothing at all. It is actually the software that makes it intelligent and gives some meaning to its life. The software defines the purpose of the 8051 or solution to a particular problem. Now how to program it? It's very simple to understand.

You're already familiar with Proteus and its usage . It's really interesting to simulate your circuit before hardware implementation because it's just a matter of few clicks here and there before you can see the output. Sometimes there are too many connections in your circuit which kind of looks ugly. This article is about using BUS WIRE in Proteus which saves you some space in the design area and the circuit also looks presentable rather than a mess of connections. READ MORE
