关于#开发板#的问题，该代码能不能实现，有无正确代码

Question

#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++)
