Sir, for implementing pwm you have to use timers. Use them with a bit of logic and you will have your pwm.

[sourabh]

void pwm();

 

void main()

{

   led=1;

   pwm();

  led=0;

  pwm();

 

}

 

void pwm()

{

  TMOD=0x01;

  TH1=0x67;    //set the value of the delay

  TL1=0xff;

  TR1=1;

  while(TF1==0);

  TR1=0;

}
