Try a LED blink program or something. The source files for the mega8 are from AVRlib - may or may not work with the mega32. I've tried with a mega644 and the avrlib source files don't work.

are you sure you can turn it on? if you can turn it on you should be able to turn it off with the right code.

i can give u a direct code for atmeaga32...it started with atmega16 but the structure of 16 and 32 are completely same..
Code: [Select]
# include<avr/io.h>
int main(void)

{
 DDRD=0x01;
 TCCR1B|=((1<<CS10)|(1<<CS11));
 while(1)
  {
  if(TCNT1>=3000)
   {
    PORTD^=(1<<2);
TCNT1=0;
   }
 
   
    }
 
   
 
 return(1);
}

this is flashing led with 1 sec gap
