LED blinking using LPC1768

LED blinking using LPC1768:
code:

#include <LPC17xx.h>

   

int main( void )

{

                int i, n=10000000;

                SystemInit();                          // System initialization

                SystemCoreClockUpdate(); // Clock initialization

                                                                                                  // Function Selection as GPIO

                LPC_PINCON->PINSEL4 = 0X00000000;   // PORT 2, 12th bit as zero, P2.12 as GPIO

                                      // set Direction of 12th pin as output by passing 1

                LPC_GPIO2->FIODIR = 0x1000;

                while( 1 )

                {              

                                LPC_GPIO2->FIOCLR = 0X1000;   // 1 Turn on LED

                                for( i = 0; i < n; i++ );                           // delay

                                LPC_GPIO2->FIOSET = 0X1000;    // 1 Turn OFF LED

                                for( i = 0; i < n; i++ );                          // delay

                }
