i think it is also can be

[Amit Joshi]

 i think it is also can be done by

 

// for left shift

for(i=0;i<6;i++)

{

PORTx = (PORTx<<1);  

_delay_ms(1000);

}

 

 // for right shift

for(i=0;i<6;i++)

{

PORTx = (PORTx<<1); 

_delay_ms(1000);

}

 

 // for cicular shift

while(1)

{

PORTx = (PORTx<<1)|(PORTx>>7); 

_delay_ms(1000);

}
