Getting Started with Keil uVision

An Introduction to Keil MicroVision

Embedded system means some combination of computer hardware and programmable software which isspecially designed for a particular task like displaying message on LCD. If you are still wondering about anembedded system, just take a look at these circuit applications using 8051 microcontroller. You can call theseapplications embedded systems as it involves hardware (8051 microcontroller) and software (the code written inassembly language).

1. Voltmeter using 8051

2. Thermometer using 8051

3. Frequency counter using AVR

Some real life examples of embedded systems may involve ticketing machines, vending machines, temperaturecontrolling unit in air conditioners etc. Microcontrollers are nothing without a Program in it.

One of the important part in making an embedded system is loading the software/program we develop into themicrocontroller. Usually it is called “burning software” into the controller. Before “burning a program” into acontroller, we must do certain prerequisite operations with the program. This includes writing the program inassembly language or C language in a text editor like notepad, compiling the program in a compiler and finallygenerating the hex code from the compiled program. Earlier people used different softwares/applications for allthese 3 tasks. Writing was done in a text editor like notepad/wordpad, compiling was done using a separatesoftware (probably a dedicated compiler for a particular controller like 8051), converting the assembly code to

hex code was done using another software etc. It takes lot of time and work to do all these separately,especially when the task involves lots of error debugging and reworking on the source code.

Keil MicroVision is a free software which solves many of the pain points for an embedded program developer.This software is an integrated development environment (IDE), which integrated a text editor to write programs,a compiler and it will convert your source code to hex files too.

Here is simple guide to start working with Keil uVision which can be used for

Writing programs in C/C++ or Assembly languageCompiling and Assembling ProgramsDebugging programCreating Hex and Axf fileTesting your program without Available real Hardware (Simulator Mode)

This is simple guide on Keil uVision 4 though also applicable on previous versions also.

These are the simple steps to get off the mark your inning!

Step 1: After opening Keil uV4, Go to Project tab and

Create new uVision project

Now Select new folder and give name to Project.

Step 2: After Creating project now Select your device model. Example.NXP­LPC2148

[You can change it later from project window.]

Step 3: so now your project is created and Message window will appear to add startup file of your Device clickon Yes so it will be added to your project folder

Step 4: Now go to File and create new file and save it with .C extension if you will write program in Clanguage or save with .asm for assembly language.

i.e., Led.c

Step 5: Now write your program and save it again. You can try example given at end of this tutorial.

Step 6: After that on left you see project window [if it’s not there….go to View tab and click on projectwindow]

Now come on Project window.

Right click on target and click on options for target

Here you can change your device also.

Click output tab here & check create Hex file if you want to generate hex file

Now click on ok so it will save changes.

Step 7: Now Expand target and you will see source group

Right click on group and click on Add files to source group

Now add your program file which you have written in C/assembly.

You can see program file added under source group.

Step 8: Now Click on Build target.You can find it under Project tab or in toolbar.It can also be done bypressing F7 key.

Step 9: you can see Status of your program in Build output window

[If it’s not there go to view and click on Build output window]

Now you are done with your program. Next time we will look at Debugging and Simulation of Program. Hopeyou find it helpful.

Really a good explanation is given very much helpful for the freshers.

Replysanjeev says:January 27, 2015 at 11:10 pm

what happens whether the startup files did not add to the poject is it necessary or not?
