Below is my code for which I have generated the hex file:

#include "lpc214x.h"

#define LED1    (1 << 10)

#define LED2    (1 << 11)

#define BUTTON1 (1 << 15)

#define BUTTON2 (1 << 16)

// Method prototypes

int getPinState(int pinNumber);

int main(void)

{

// Set buttons as input

PINSEL0 &= ~(BUTTON1 | BUTTON2);

// Set LEDs as output

PINSEL0 |= (LED1 | LED2);

// Turn both LEDS off (set them 'high')

IO0SET |= (LED1 | LED2);

while (1)

{

    // Check if button 1 is pressed

    // Released = 'High' (1)

    // Pressed = 'Low' (1)

    if (getPinState(15))

    {

      // Button1 is currently 'high'

      // Turn LED1 off

      IO0SET |= LED1;

    }

    else

    {

      // Button1 is currently 'Low'

      // Turn LED1 on

      IO0CLR |= LED1;

    }

}

}

int getPinState(int pinNumber)

{

// Read the current state of all pins in GPIO block 0

int pinBlockState = IO0PIN;

// Read the value of 'pinNumber'

int pinState = (pinBlockState & (1 << pinNumber)) ? 1 : 0;

// Return the value of pinState

return pinState;

}

Also attached is my PROTEUS simulation model. But in PROTEUS I am getting error?
