hello friend,
i was used an ic atemag32,in it i programmed and it work well for adc,uart,ext interrupt,timer all...but some days before i bought 3 new atmega32 ics,i placed it in my old board and burned the same old working program, but the adc is not working in new 3 ics...i am using avr studio complier.then i compired the fuse settings of working and non working ics... both are same....then i used sinaprog to set the fuse settings.. and changed and made all the settings are same as working ic in sinaprog too.. but its not working adc for new ics,... here i attached two screen shot of my sinaprog fuse settings of two microcontrollers.one is working old ic and another is not working new ic.. i changed the fuse settings of non working controller as like the working one.i changed all the fuse settings as like the working one but the calibration value is still non changing, and it constant for all fuse value settings.. how can i change the calibration value as like the working microcontroller calibration value.Both has same fuse settings but the calibration value is seen as different..please help me to detect the error..... thank you....

The problem seems to be with fuse bits,
Try
LOW EF Hex
HIGH C9 Hex
Just try and you can revert to original values if needed.
For further details you can refer online fuse bit calculator for AVR microcontrollers.
 

@ark5230.. thanks for your support... my issue solved when i write a new program,, but still dont know why my previous program work well in old ic and not in new ics...
