通過(guò)15單片機(jī)外接esp8266,串口顯示確是一直為空

esp8266返回的數(shù)據(jù)通過(guò)數(shù)組接收，但是在串口顯示確是一直為空大家?guī)臀铱纯�，這是為啥啊

代碼如下

unsigned char Usart_Receive[50]={0};
unsigned char Usart_Cnt=0;

void Init(void)
{

            PCON &=0X00;
            SCON = 0X50;
            AUXR |= 0x40;
            AUXR &= 0xFE;
            TMOD &= 0x0F;
            TMOD |= 0x20;
            TL1 = 0xDC;
            TH1 = 0xDC;

            ET1 = 0;
            TR1 = 1;
            EA = 1;
            ES = 1;
            REN=1;

}

void main()
{

Init();
            ESP8266_Init_weather();
            AT_Send_String(Usart_Receive);
            led = ~led;
while(1);
}

void InterruptUART(void) interrupt  4
{

      if(RI)
      {


            Usart_Receive[Usart_Cnt]=SBUF;
            Usart_Cnt++;
            RI=0;
      }
            if(*Usart_Receive!=NULL)
            {
                     if(Usart_Receive[Usart_Cnt]=='\0')
                     {
                              led = ~led;
                              Usart_Cnt=0;
                              Usart_AT_flage=1;
                     }

            }
            else
                     TI=0;

}

8266內(nèi)的程序是你寫的不？和單片機(jī)是如何配合操作的？
