We are going to use an Arduino Uno as an to program the AT89S52 microcontroller. From Atmel are compatible with Intel’s popular microcontroller.In order to use Arduino as an ISP, we have to burn the ArduinoISP sketch to Arduino itself. Launch Arduino IDE and open the ArduinoISP sketch from:File - Examples - 11.ArduinoISP - ArduinoISPWe will be using pins 10-13 of the Arduino, instead of the ICSP header, so we need to define that into the ArduinoISP sketch before we build/upload it. Go to line 81 and uncomment the following: #define USEOLDSTYLEWIRINGSave, Compile and Upload ArduinoISP to Arduino.Next, we connect the Arduino Uno with the AT89S52 as follows.

Programming the AT89S52 microcontroller with Arduino Uno as an ISPThis is a list of the components I used in the above circuit:. XTAL 11.0592MHz. 2x 22pF capacitors for the crystal.

10uF capacitor. 220Ω resistor for the LED. 10KΩ resistor. red LEDI decided to use Keil uVision to build a basic program (blinky) for the AT89S52. You can use the open-source (C compiler for 8051/AT89SXX) as an alternative.

For uVision to support the AT89 targets, I had to install the before anything.We can now start a new Keil uVision project targeting the AT89S52. Select Project - New uVision Project. On the following dialog select the “AT89S52” target from the “Legacy Device Database” (which was added when we installed the C51 development tools).

Normally we are designing a circuit and connecting to different other components like motors, LCDs, LEDS, even more by giving a power supply which is used by that circuit. What the microcontroller does when it is programmed with that circuit?The microcontroller families understands a program which is written in assembly level language or C language which has to be compiled into a machine level language which is known as binary language ( i.e. Free socialengine themes for women. Zeros & ones). The file which has been programmed is stored on a computer hard disk or memory of the microcontroller.

The assembler is used to translate the assembly program into machine code. To write the program in assembly language the programmer must have knowledge on the CPU or hardware. The low level languages are used in cross development. The hexadecimal system was used as more efficient way to represent binary numbers, while using binary language the CPU works very fast. Today, we can use many different programming languages such as C, JAVA, ORACLE and others. These languages are called high level languages; to write the program in high level language the programmer doesn’t need any knowledge on hardware which is used for high level application development.

The compiler plays a vital role in translating the high-level program to machine level as the high level languages are used in native development.Here are some tools which are used in programming of the microcontrollers. Keil uVsion SoftwareGuide to Start working with Keil Uvison:1. Click on the Keil Vision Icon on Desktop.The following steps involve in this process: Figure 12. Click on the Project menu from the title barThen Click on New Project Figure 23. Save the Project by typing suitable project name with no extension in your own folder sited in either C: or D:Figure 34. Then Click on save button above.Select the component for u r project. AtmelClick on the + Symbols as for your requirement. Example here selected Atmel.

Select AT89C51 as shown below Figure 56. Then Click on “OK”The Following steps involve in the above process: Figure 67. Then Click either YES or NOmostly “NO”.Now your project is ready to USE.Now double click on the Target1, you would get another option “Source group 1” as shown in next page. Click on the file option from menu bar and select “new”. The next screen will be as shown in text page Figure 910. Now start writing program in either in “EMBEDDED C” or “ASM”.For a program to be written in Assembly language, we must save it with an extension “.

Asm” and for “EMBEDDED C” based program we have to save it with extension “.C” Figure 1011. Now right click on Source group 1 and click on “Add files to Group Source” Figure 1112. Now select as per your file extension given while saving the file.Click only one time on option “ ADD”.Now Press function key F7 to compile. Any error will appear if so happen.If the file contains no error, then press Control+F5 simultaneously.Code Editor or Text Editor:The code editor is used to write the program. The uVision editors include all standard features like color syntax highlighting and quickly identify the errors. The editor is available while debugging. The natural debugging environment helps you quickly in identifying and correcting the errors in your program.

After writing the program in code editor save that file in.asm or.C format depending on which assembler you have chosen. Keil Uvison EditorAssembler:The assembler is used to convert the source code (low level language) into machine level (binary format).Compiler:The compiler is used to convert the source code (high level language) into machine level (binary format).The assembler converts the instructions into machine code:Assembly Language to Machine Level Conversion Diagram➢ The first file is created with an editor such as DOS edit or other.➢ The assembler will produce an objective file and a list of file. The extension for the object file is “.obj” while the extension for the list file is “.lst”.➢ The assembler requires a third step is know as linking. The link program takes one or more objects files and produces an objective file with the extension “.abs”.➢ The “.abs” file is fed into a program called OH (objective to hex converter) which creates a file with extension “hex” that is ready to burn in to microcontroller ROM.

Burner/Programmer:The Programming or burning a microcontroller means “to transfer the program from compiler to the memory of the microcontroller”. The program for the microcontroller is generally written in C or assembly language, finally the compiler generates a hex file which contains the machine language instructions like zeros and ones that understandable by the microcontrollers. It is the content of the microcontroller which is transferred to the microcontroller, once a program is transferred to the memory of the microcontroller it works according to the program. Programmer/Burner How to Program a Microcontroller:Microcontroller is an integrated chip in which we store the code which is written in an assemble language.

So to dump this coded program into a microcontroller IC we need a device which is known as burner or programmer. A programmer is a hardware device with software which reads the content of the hex file which is stored on a pc or laptops.

It’s read the hex file data serial or USB cable and transfer the data to the memory of the microcontroller.The programmers and compilers are different for different microcontroller which is for different companies like the 8051 microcontroller “flash magic” is used to program the microcontroller and AT89C51 microcontroller “programmer” used to program the microcontroller. This is way how we are programming code in a microcontroller with a burner or programmer.
