IAP15F2K61S2芯片 建立什么工程呀？为什么我打开程序进去全是ff

#include <reg52.h>

sbit HC138_A = P2^5;
sbit HC138_B = P2^6;
sbit HC138_C = P2^7;

void Delay(unsigned int t)    
{
while(t--);
while(t--);
}

void LEDRuning()
{ 
unsigned char i;
     HC138_C = 1;
     HC138_B = 0;
     HC138_A = 0;

        for (i=0;i<=3;i++)
                {
     P0 = 0x00;
      Delay(60000);
      Delay(60000);
          P0 = 0xff;
        Delay(60000);
        Delay(60000);
        }
        for (i =1;i<=8;i++)
        {
        P0= 0xff << i;
            Delay(60000);
        Delay(60000);
                      }
        for (i =1;i<=8;i++)
        {
        P0= ~(0xff <<i);
            Delay(60000);
        Delay(60000);
                      }

}
void main()
{
    while(1)
    {
        LEDRuning();
    }
}

哪里全是FF?
