Downloader Mikrokontroler AT89S51/52

for elinners friends or hobbiest who wants to make Easy Downloader Atmel AT89S51/52 but not knowing the circuit & program, you can try the following series.

To make it easy and very cheap. Incidentally I also tried and this downloader circuit can work well.

This series circuit AT89Sxx more simple, practical, inexpensive, but not least at his brother because the series adopted AT89Cxx ISP (In System Programming). How simple is not ... circuit just UC, crystals, capacitors, resistors with wires soldered a little, so its downloader.

For the program do not worry, there are many software that supports the ISP. One of them AT89xx program under artificial Win98/2000/ME/XP ugm children, the program can be copied here.

Instructions how to download to the microcontroller assembly:
1. Copy the file to a folder AT89SXX.exe such as c: \ micro which in this folder there are files in the assembly which will be compiled.
2. Double-click the file AT89SXX.exe
3. Click File-Open and select the file that H51 will be compiled, so it will appear listing the program on the memo.
4. AT Command menu is a menu of operations for files opened, consisting of:
a. ASM51 = H51 to change the file OBJ files and LST
b. To Hex OBJ = OBJ file to change the Hex file Intel
c. Hex To Bin = change the HEX file to a BIN file for the micro didownloadkan type AT89CXX
d. Auto = perform the process of a through loading files into memory buffer PC automatically
5. Make a setup kind of IC that will be programmed by pressing the letter 'J'.
6. Set high on the logic reset by pressing the letter 'I'.
7. Microfinance programs by pressing 'E'.
8. To load another hex file then press 'A' and enter your HEX file name in full eg: coba.hex
In this way then your program is stored in the microcontroller.
