SPI problem

hello

I use LPC H2129 with µvision, I wants to communicate with the SPI to order one LCD. I took the code from Philips but not work, (I sees nothing on the oscilloscope) I joint you it , thank you for the assistance

#include"LPC21xx_keil.h"

void Initialize(void);

/* Macro Definitions */

#define SSEL 7

/************************* MAIN *************************/

int main()

{

IOSET0=(1<<SSEL);

Initialize();

/* Do forever */

while(1)

{

/* Write data out */

S0SPDR=0xCA;

/* Wait for transfer to be completed */

while(!(S0SPSR &0x80)){}

}

}

/*************** System Initialization ***************/

void Initialize()

{

/* Configure Pin Connect Block */

PINSEL0=0x5500;

/* Set pclk to same as cclk */

VPBDIV=0x1;

/* Set to highest speed for SPI at 10 MHz- > 1.25 MHz */

S0SPCCR=0x8;

/* Device selected as master */

S0SPCR=0x20;

}
