why我的UART1不产生接收中断啊 [复制链接]

DX帮我看一下，为什么我的UART1不产生接收中断啊!!
初始化如下：

//////////////////////////////////////////
///串口1初始化
void Uart1Init(void)
{
//使能所有要用APB2的外设时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB |
                         RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOD |
                         RCC_APB2Periph_GPIOE | RCC_APB2Periph_USART1, ENABLE);
///////////////////串口IO初始化/////////////////////
GPIO_PinRemapConfig(GPIO_Remap_USART1, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;  //uart1_txd
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOB,&GPIO_InitStructure);
////////
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7;  //uart1_rxd
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOB,&GPIO_InitStructure);
///////////////////////////////////////////////////////////////
USART_InitStructure.USART_BaudRate = 9600; //9.6kbps
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;

USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;

USART_ClockInitStruct.USART_CPOL = USART_CPOL_Low;
USART_ClockInitStruct.USART_CPHA = USART_CPHA_2Edge;
USART_ClockInitStruct.USART_LastBit = USART_LastBit_Disable;

USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);  //使能UART1

}

        NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQChannel;
//        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
        /* Enable the USART2 Interrupt */
        NVIC_InitStructure.NVIC_IRQChannel = USART2_IRQChannel;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
}

会的朋友帮我看一下，谢谢了，我的两个串都不进入不了接收中断，可以接收波形已经到了IO口了，就是不中断！

你在哪里使能了USART1的中断了？
你使用了Remap，在哪里使能AFIO时钟了？

请参考STM32固件库中的例程好好看看吧。

                                 不行，是得好好看看资料了，Remap好像没打开
