Blinking led with LPC2138

[vead]

Hello

I want to blink led with LPC2138 on proteus simulator. I have written program on keil but I am not to see led blink

This is my code

#include <LPC213X.H>

void delay(unsigned int wait);

void delay(unsigned int wait)
{
    unsigned i;
    for( i = 0; i < wait; i++)  
    {  
		   }
}

int main (void)
{
	    IODIR0 = 0x000000FF;         //Port-0.0 to Port-0.7 pins as Output Pin
	
	while (1)
		
	 {
		     IOSET0 = 0x000000FF;             //P0.0 to P0.7 are high
	     
		   delay(5000);
	      
		   IOCLR0 = 0x000000FF;            //P0.0 to P0.7 are low
	  
     		 delay(2000);
	 }
	 
 }

What is problem

I'm not familiar with this chip or proteus, but don't you need an oscillator or crystal or something? Also, if you've got a nominal clock of, say, 10MHz, your blink rate is going to be extremely fast (700uS)
