compare mode of PIC18f4584

HI,

I am using PIC18f4585 ,I have to generate a frequencies from 23.8 to 166Hz using CCP module in compare mode. but I am not able to generate this

my code is
#include<p18f4585.h>
//_CONFIG1H = 0x09;

//#define
#pragma config OSC = IRCIO7
//#pragma config PWRT = ON
#pragma config BOREN = OFF
#pragma config WDT = OFF
#pragma config MCLRE = ON
#pragma config PBADEN = OFF
//#pragma config CCP2MX = PORTC
#pragma config LVP = OFF
#pragma config DEBUG = ON

void pwm_configure(void);
void BIT16_PWM(void);

main(void)
{
OSCCON = 0x67;
OSCTUNE = 0x80;

TRISD = 0x00;
PORTD = 0x00;

CCP1CON = 0x00;
TMR1H = 0x00;
TMR1H = 0x00;
TRISC = 0x00;
T1CON = 0x30;
T3CON = 0x00;
PIE1bits.CCP1IE=0; // Enable Capture/Compare CCP1 interrupt
INTCONbits.PEIE=0; // Enable peripheral block interrupts
INTCONbits.GIE=0; // Enable maskable interrupts as whole

CCPR1H = 0x7F;
CCPR1L = 0xFF;

CCP1CON = 0x02;

T1CON |= 0x01;

//BIT16_PWM();
//pwm_configure();
while(1);
}

void pwm_configure(void)
{
PR2 = 0x32;
ECCPR1L =(unsigned char)(PR2*0.75);
//CCPR1L =(unsigned char)(PR2*0.05);
TRISD = 0x00;
TRISC = 0X00;
TMR2 = 0x00; // LOAD 8 BIT VALUE IN TMR2 00 to FF =>256 steps
T2CON = 0x04; // TIMER ON ,postscaler OFF ,prescaler OFF
//CCP1CON = 0x0C;
ECCP1CON = 0x0C; // PWM MODULE ON
//CCP1CON |= 0x20;

}
void BIT16_PWM(void)
{
CCP1CON = 0x00;
TMR1H = 0x00;
TMR1H = 0x00;
TRISC = 0x00;
T1CON = 0x30;
T3CON = 0x00;

CCPR1H = 0x7F;
CCPR1L = 0xFF;

CCP1CON = 0x02;

T1CON |= 0x01;
PIE1bits.CCP1IE=0; // Enable Capture/Compare CCP1 interrupt
INTCONbits.PEIE=0; // Enable peripheral block interrupts
INTCONbits.GIE=0; // Enable maskable interrupts as whole

please anybody help me to do so.

If possible give me a sample code for CCP module in compare mode, and also how to calculate CCPR1 values .
