[cannon]

I had successfully completed d $50 robot with ATmega8..

I hav been using the same code as be4..
I just changed d pin numbers to that of 32..
shd i change the SoR_utils, etc to make it wrk for 32??

Change the MCU name in the makefile to atmega32

[cannon]

did tht..
wht i basically wanna knw is whether it wil wrk with the old header files??

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.

see everything has to be changed...atmega32 has a diff set of pins and also registers inside it...the same program wont work...u have to change the initialization part and many more . .

i had tried led blink program.. prob is port can be turned on only, it cant be turned off..

and i'm not tht much of a prog genius..
can anyone giv me prog with req initializations for atmega32??

or atleast some place whr i can find instructions for d same??

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.

[cannon]

for eg, if i giv
PORT_ON(PORTB,0), only tht turns on..

but it doesnt turn off by giving,

PORT_OFF(PORTB,0)

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
