Microcontroller Programming AT89S / XX
Once you memahani basic things with regard to microcontrollers, including the Constitutional Court architecture includes CPU, memory, I / O ports, and additional peripherals, then know the various terms and the common parts of the pins Court. The next important part is programming techniques and matters related to pemrogramana. Programming development very rapidly with the development of the microcontroller technology sensdiri.
Beginning with samapai assembler language with high-level language, the current user can be digunakansesuai memeilih language with compiler (translator). At this learning activity as a beginning to learn microcontroller introduced assembele language, but for the further development you are allowed to learn the language of high-level languages such as Basic, C, Pascal, Java and other language variety in accordance with the development of information and communication technology.
You can write assembler program on a note pad and then in the compiler uses ASM51 or Mide. M-IDE Studio is one of the ways used to run the compilation for MCS-51 components. M-IDE Studio has several features that can be used to edit, compil, and debug files. The M-IDE Studio can also be used to write programs in C. By using this software, we can see the error in the report file LST

If you look at the menu toolbar and menu options may be seen disable. This is because the file has not been made. To create a file, perform the following steps:
1. Create New File To create a new file, click on the File menu or short cut as shown in the picture, so it would seem a blank page.
Figure 36 The new file with a blank page
2. Write a program Write the assembly program on a blank page, and do file storage. If the file has been saved it will appear a text instruction colorful. As shown in Figure 1:35.

3. Compile the file with the extension order for the ASM can diloadkan to the microcontroller, it is necessary to compile from ASM file to HEX.
4. Debug

By using a microcontroller AT89S microcontroller programming can be done by means In System Programming (ISP). Meaning IC microcontroller does not need to be removed plug for programming. To download the program can use artificial programmer ISP M. Asim Khan or Asp Avr Usb Downloader and 8051.
