Hai, Bharat Raj,<br />
1. Which crystal you have used?<br />
2. Did you set the speed to less than crystal frequency/16?<br />
3. <strong>In</strong> the set up did you use AEC <strong>ISP</strong>?<br />
4. Whether the port used is LPT1.<br />
5. what type computer you use? Did you check +5V? or itis less?<br />
6. Did you pull up the pin31 as generally needed.<br />
Regards<br />

Hai, Bittu,<br />
Many times it is mentioned that it is <strong>for</strong> only 89S51 and 89S52<br />
however the list of devices possible is gine in the software package and see them by pressing<br />
SETUP and pressing a button at the device select.<br />

[Quoting: Bozo] I just won´t to say thank you wery much. I´m more then the satisfied with<br />
this programer. It isn´worked from the first time, so I modified it. At the end of the cable<br />
from the programer to the target board, I put the resistor 330E in serial with te sck line and<br />
then capacitor 120pF from the sck to gnd. Since then I have no problem. I have programed<br />
At89s2051 and Atmega8. Hello from Slovenia, Bozo<br />
Nice Bozo, you sorted out the issues and happy that it works!!Lovely<br />

[Quoting: jigesh mehta] I am design <strong>ISP</strong> programming cable <strong>for</strong> at89s52 microcontroller.<br />
but <strong>In</strong> that i have not programe the IC AT89S52. I am seting AEC-<strong>ISP</strong>.I have problem is<br />
give Device signature is differant when many times cilk on read signature. so give help...<br />
Hai Jigesh, At the right side top there is one button called "setup". press it and at the bottom<br />
of the new window youhave the device select.<br />
either you can set it by manual selection by clicking don't autodetect. press the button<br />
adjecent and a list of devices opens up. go to the device you want and select it<br />
therafter you go ahead. AEC <strong>ISP</strong> is a method LPT pins are selected. <strong>for</strong> what we are are using<br />
it is AEC <strong>ISP</strong><br />
All the best<br />

I beg to offer correction please see the circuit published by IKA, and specifically stated that no<br />
crystal needed. thus we pay put it in fastest speed option and software will take care of. also<br />
pin31 is shown connected to ground in ATMEGA16<br />
Thus ATMega32 may follow suite and the best would be to check with datasheet of ATMega32.<br />
