Interfacing 7 segment with ARM LPC 2148

In this Post, I am going to show you that how can you Keil for LPC 2148 which is an ARM-based microcontroller
In this post, I am interfacing 7 segments with LPC 2148

LPC 2148 datasheet can be downloaded from here




pin connection  of 7-seg

data     P0.16 to P0.23
control  P0.8 to P0. 15




C Code for programming LPC 2148 using Keil uVision 4  MDK

#include"lpc214x.h"


int main()
{
int a;
unsigned char arr[] = {0xbf, 0x86, 0xdb, 0xcf, 0xe6, 0xed, 0xfd, 0x87, 0xff, 0xef};
IODIR0 = 0xffffffff;

while(1)
{
for(a=0;a<=9;a++)
  { 
          IOCLR0 = 0xffffffff;
          IOSET0 = arr[a]<<16 | 0x0f00;
          delay_ms(1000);
  }
}
}

void delay_us(unsigned int count)
{
  volatile unsigned int j,k;
  for (j=0;j<count;j++)
{
    for (k=0;k<10;k++)
{
       __asm
{
                nop;
      }
    }
  }
}
void delay_ms(unsigned int count)
{
