关于#开发板#的问题，该代码能不能实现，有无正确代码

#include "ioCC2530.h"

#define LED1 P1_0

#define LED2 P1_1

#define LED3 P1_3

#define LED4 P1_4

#define SW1  P1_2

unsigned int counter=0;


void delay(unsigned int time)

{ 
  
  unsigned int i;
  
  unsigned char j;
  
  for(i = 0; i < time; i++)
  
  {  
    
    for(j = 0; j < 240; j++)
    
    {   
      asm("NOP");
        
      asm("NOP");
        
      asm("NOP");
    
    }
  
  }

}


#pragma vector=P1INT_VECTOR

void main()
{

  while(1)
    {
      switch(counter){
      case 1:
        PRESSBUTTON1(); 
        break;
      case 2:
        PRESSBUTTON2();
        break;
      case 3:
        PRESSBUTTON3();
        break;  
      case 4:
        PRESSBUTTON1();
        break;   
      default:

实际运行一下就知道能不能用了啊
