HI......
is there anyone who knows about AT89s51 USB programmer???... if someone does, can you post some info here how to build it... COz' i confuse how to download program using my laptop..... THANK YOU
I have programmed Atmel microcontrollers in the past using In-System programming in conjuction with my laptops serial port. If you do a search on the internet you will find many usefull documents!
Added after 42 seconds:
Using a simple 6-pin header connector pinout, used by the AT90ISP cable, the AVR In-System programmer communicates serially with the AVR microcontroller and reprogrammes it.
There is a simple ISP programmer by Asim Khan, I tried version 3a, easy cheap and reliable.
Use the ISP, I did not try SPI, it is more comples than ISP. This needs printer port.
for USB Port AVR Programmer is available at a affordable price by: **broken link removed**

There are so many serial port programmers for AT89S51/52 micrcontrollers but are not very useful when it comes to laptops (lack of serial port). Try usb programmer by protosmart. Its Smartpro s51 i think.
