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

    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;

    }
