Yes, COM1 port echoed back the characters that I wrote means COM1 port runs successfully.

But it cannot program my AVR :-(
 

The 5v pin in the ICSP header of the programmer is to give 5v to the programmer (input), it is not a 5v output, have you connected it to power supply (and also the atmel chip)?
 

Maybe it can be a problem with the baud setting of the hardware port and the setting in ponyprog, I don't use it so I don't know if there is such a setting.
Open the device manager of windows and try with different baud rate.

Are you currently trying to program mega8?
And it has never been programed before?
 

AVR is Atmel :?:

I'm not sure what you can be doing wrong and you can't make it work.
Maybe if you provide an image of your connections we can see something
 

Please let me know that my power supply gives 4.9v not exact 5v,will it effect the programming or not?

Yes,Yes Yes programmer runs successfully when restarting laptop,Thanks alexan_e very very very thankful to you :-D .

Also thankful to you dear BigDog.

Please let me know which hex file will burn in the ATmega8 for making it USBasp.
 

I wrote a program of LED blinking for testing for confirmation of burning hex file in ATmega8 but LED could not blink what would be a problem please let me know?


#include<avr/io.h>
#include<util/delay.h>
#define LEDs PORTD
main()
{
DDRD=0xFF;
while(1)
{
LEDs=0;
_delay_ms(500);
LEDs=255;
_delay_ms(500);
}
}
 

Please let me know that can you arrange the components in the EAGLE board for USBasp , they cannot arrange by me properly.
 

Well, you were the one who wanted to make a DIY programmer and not buy a ready one , right?
That means to learn in the process, no software will make good placement automatically and if someone else does it for you then you will not learn , and that being said you might as well get one of the ready PCB designs available if you don't want to do it yourself.
Finally, I don't use eagle.
 

It was program the AVR successfully but after connecting to breadboard the AVR could not make desired output.

Only 5v appeared on every port of AVR .I built LED blinking program. And finally ponyprog could not program after 10 to 20 times programming.
 

That doesn't make sense, the mcu can be programmed thousands of times.
If the programmer was/is working then why build another one?
 

Means that ponyprog cannot detect AVR serial programmer after 10 or 20 successive burning.

And when I did program the ATmega8 then ATmega8 does not gave output.
