就是2个串口同时工作的中断初始化
不知道我的初始化有没有问题，我对中断不是很精通，初学者。麻烦大神们给点提示。串口1能产生中断，用仿真调试感觉串口2不能产生中断，不知道我的中断初始化哪里出了问题。谢谢

//系统中断管理
void NVIC_Configuration(void)
{
          NVIC_InitTypeDef NVIC_InitStructure;

  
          /* Set the Vector Table base location at 0x20000000 */
//          NVIC_SetVectorTable(NVIC_VectTab_RAM, 0x0);

          /* Set the Vector Table base location at 0x08000000 */
          NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0);   


        /* Configure one bit for preemption priority */
        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
          
        /* Enable the USART-1 Interrupt */
        NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
//        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);

        NVIC_InitStructure.NVIC_IRQChannel = USART2_IRQn;
//        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
