The International Distance Contest on Application Programming Microprocessor-based Systems in Assembler Language for MCS-51 Standard Microcontroller
Software Installation
To install the software, first unzip the file archive on the C drive in folder C:\ asm_8051.Files List of “ASM Editor for Windows” programming environment (for Windows)
ASM_Ed.exe - Code Editor AsmEd.ini - Configuration File Editor Default.shk - Keywords file default x8051.shk - Keywords file for the AT89C51 Microcontroller
Files List of translators from Assembly language: x8051.exe - cross-assembler for the i8051 family processor link.exe - program linker MyLink.exe - program for both assembling and compiling followed by the outputs
on a display MyLink.zip - the source code in Delphi for MyLink.exe
Also in the folder C: \ asm_8051 we will create the directories: ASM, HEX, OBJ. ASM directory is intended to store the programs in Assembly language (*. asm). When compiling files in HEX and OBJ folders the files will be created with the appropriate extension (*. hex and *. obj), which are used to download the programs in in-circuit emulator.
How to operate in this program
To run the program one must run ASM_Ed.exe.

There are the following areas of the main program window (Figure 1): Main menu (1) Quick access buttons to the functions of the main menu (2) Area for writing programs (3).
Let’s consider the most important functions of “ASM Editor” program.

When developing the program in the environment of “ASM Editor” the following procedure is recommended:
1. Start the “ASM Editor” (ASM_Ed.exe).2. In area for writing program, first enter the text of the program, using the syntax and rules
for writing programs in assembly language.3. Save the program (by choosing File> Save or by clicking on the toolbar).Save the program on the folder C:\asm_8051\asm disk. The file name should be written
in Latin characters and contain no more than 8 characters.4. Compile a program by selecting Project> Compile Resource. This item allows you to
start the process of compiling the program and simultaneous error checking and then the process of linking the compiled program. When an error occurs, error messages appears on the screen (see Figure 2), and linking is not performed. To close the error message, press any key.

If compilation is successful, the message of a successful compilation will appear on the screen (Figure 3). In the HEX and OBJ folders the files have been created with the appropriate extension (*. hex and *. obj). To close the message box after a successful compilation, press any key.
