To flash the LED
Code:

int i=0;

While(i<30)
  {
   Output_high(PIN_D1);
   Delay_ms(500);
   Output_low(PIN_D1);
   Delay_ms(500);
   i++;
  }

That should flash your led for 30 secs....

As for the PWM.... I can't help you there. I only used sofware PWMs for RGB LED control not motors.

I believe you need a speed ramp.

look on google Trapezoidal Ramp, furthermore, PCM programmer gave us an example about it:
