this is the PWM initialization code which I used for audio out. Any way, you just read the PWM part in the datasheet and then try to understand the below code.
Code: 
void pwm_init()
     {
      TRISC1=0;
      T2CKPS1=0;
      T2CKPS0=0;
      PR2=0x50;
      CCPR2L=0x17;
      TMR2ON=1;
      CCP2CON=0b00001100;
      }

void pwm_disable()
	{
	CCP2CON=0b00000000;
	}

void pwm_enable()
	{
	CCP2CON=0b00001100;
	}
----------------------------------------------------------------------------------------

Now update the value in CCPR2L register to change the dutycycle.

I don't know even basics of PMW.
Can anyone help me to learn it?
