7-Segment Interfacing with LPC2148 HELP

[amayilsamy]

I want interfacing 7-segment with lpc2148.

I'm using the port pins is [a:dp] =P0[8:15]

First I need a code for HOW ON/OFF P0[8.15] only.

I wrote code already but it is not working

I post my code here....

	#include<LPC214x.h>

	#include"defines.h"

	#include"delays.c"

	int main(void)
	
		{
			
			PINSEL0 = 0x00000000;
			
			IO0DIR &= 0xFFFFFFFF;

			while(1)
			{
			
			IO0SET &= 0xFFFFFFFF;

		

			
			delay_ms(2500);

			IO0CLR |=0xFFFFFFFF;
			

			
			delay_ms(2500);
			
			}		

		}

defines.h code..

 # define IO0PIN = (IO0PIN && 0xFFFF00FF) && 0x0000FF00 ;
