使用该芯片编写串口接收，可进行串口扫描接收，无法进入中断接收！请高手帮忙。程序配置如下：
void USART1_Config(void)
{
        GPIO_InitTypeDef GPIO_InitStructure;
        USART_InitTypeDef USART_InitStructure;

        /* config USART1 clock */
        RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);

        /* USART1 GPIO config */
   /* Configure USART1 Tx (PA.09) as alternate function push-pull */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);   
  /* Configure USART1 Rx (PA.10) as input floating */
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOA, &GPIO_InitStructure);
          
        /* USART1 mode config */
        USART_InitStructure.USART_BaudRate = 115200;
        USART_InitStructure.USART_WordLength = USART_WordLength_8b;
        USART_InitStructure.USART_StopBits = USART_StopBits_1;
        USART_InitStructure.USART_Parity = USART_Parity_No ;
        USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
        USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
        USART_Init(USART1, &USART_InitStructure);
  USART_Cmd(USART1, ENABLE);
}
void USART_Configuration(void)
{
        NVIC_InitTypeDef NVIC_InitStructure;
        /* Configure the NVIC Preemption Priority Bits */  
        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
       
        /* Enable the USARTy Interrupt */
        NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;         
        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
}

没有配置中断啊，USART_ITConfig()函数
