In System Programmer (ISP) for ATMEL micro controllers http://www.ikalogic.com/isp.php Page 8 of 29 26-02-2008 this article. Setting up the software to be used with the programmer hardware If it doesn't work...: Now if your programmer doesn't work, don't panic and check the following: 1- Make sure the cable is no longer than 50 cm (though i made it work with a 1meter cable..) long cables tend to increase noise interference especially with TTL devices. 2- Try more than one device, I had two AT89S52 which which had their ISP port damaged somehow, as they could be programmed through the parallel programmer and functioned correctly, but wouldn't let me to program them through ISP 3- If you can read a hex file, which was written by any other programmer , but you CANNOT Write another HEX file using the ISP programmer, this is - without a doubt - caused by a damaged chip. 4- Contact me, if the solutions above didn't work.

Reply With Quote Do yourself a favor and get the real software on the atmel site.This program works sometimes and sometimes it is very troublesome!This code is just another type like asim Khan's program. It should not matter how long the cable is as long as it is shielded (no longer than 3 ft, mind you)Using the parallel port like this is very troublesome. Because all PC's are different, and all parallel ports are different, it can work perfectly for one person and NEVER work for the next guy.I could read the signature bytes every single time, but never program the device. I have more than one 89S51 and they are NOT damaged! It is the poorly written software. Good Luck Reply With Quote [Quoting: Chris Keays] Do yourself a favor and get the real software on the atmel site.This program works sometimes and sometimes it is very troublesome!This code is just another type like asim Khan's program.

Good Luck I forgot to add, with my current setup (nothing changed) I used the ISP software I downloaded on the atmel site and it worked perfectly, same cable, same programmer, same PC! So what does that tell you?? Well, that tells me i've got to try ATMEL's software...

So what does that tell you?? Plzz tell me can i download program with this programmer and cable in 89C51. Reply With Quote Reply With Quote [Quoting: Jawad Lateef] Plzz tell me can i download program with this programmer and cable in 89C51. No, this programmer is only compatible with ISP powered devices like the 89SXX. Note that you'r program will work on a 89S51 exactly as it will work on a 89C51.
