LPC1343 Timer

Hi dears ,

I want to write a program to blink an LED each 1 second. I've wrote below code but after loading into the MCU, it does not work at all. Would you let me know how can I do it, please ?
<
#include "LPC13xx.h"
#define PRESCALE 60000 ;

void delayMS(unsigned int milliseconds);
void initTimer0();

int main()
{

LPC_SYSCON->SYSAHBCLKCTRL = (1<<7); initTimer0(); LPC_GPIO0->DIR |= (1<<3) |(1<<4); LPC_GPIO0->DATA = 0x0;

while(1) { LPC_GPIO0->DATA |= (1<<3);

LPC_GPIO0->DATA |= (1<<3); delayMS(500); LPC_GPIO0->DATA &= ~(1<<3); delayMS(500); LPC_TMR16B0->TCR = 0x0; //disable counter }
}

void initTimer0()
{ //LPC_TMR16B0->CTCR = 0x0; LPC_TMR16B0->PR = PRESCALE-1; LPC_TMR16B0->TCR = 0x02;//reset timer

}

void delayMS(unsigned int milliseconds)
{ LPC_TMR16B0->TCR = 0x02;//reset timer LPC_TMR16B0->TCR = 0x01;//set timer while(LPC_TMR16B0->TC < milliseconds); LPC_TMR16B0->TCR = 0; //disable counter
