14 segment and16 segment using ARM

WAP to Display 'A' on 14 segment:

#include<lpc21xx.h>
//#include"delay.h"

void delay(unsigned int c)
{
    unsigned int a;
for(a=1;a<=60000;a++);
}
int main()
{ int i;
  PINSEL0=0x00000000;
    PINSEL1=0x00000000;
    IO0DIR=0xffffffff;
   
while(1)   
{
    i=0;
while(i<100)
{   
    IO0SET=0x2633;
    delay(100);
    IO0CLR=0x2633;
    delay(1);
    i++;
}
while(i<200)
{
    IO0SET=0x2237;
    delay(100);
    IO0CLR=0x2237;
    delay(1);
    i++;
}

while(i<300)
{
    IO0SET=0x0176;
    delay(100);
    IO0CLR=0x0176;
    delay(1);
    i++;
}
}
}

WAP to Display 'RAM' on 14 segment using multiplexing:

#include<lpc21xx.h>
//#include"delay.h"

void delay(unsigned int c)
{
    unsigned int a;
  for(a=1;a<=60000;a++);

    IO0SET=0x2633;
    delay(100);
