如题，在进行sx1278驱动移植时报错很多个"IRQn" has already been declared in the current scope，发现问题是在stm32f10x.h

（GPIO）四、工程的配置五、代码生成的串口中断代码如下：void USART1_IRQHandler(void){ /* USER CODE BEGIN USART1_IRQn 0 */ /* USER CODE END USART1_IRQn 0 */

USART1（单片机串口1使用usb-串口与pc连接）。在对串口和io初始化后，我们要对串口进行中断设置和优先级设置以便于我们处理串口发送的数据。HAL_NVIC_EnableIRQ(USART1_IRQn); //使能 USART1中断通道HAL_NVIC_SetPriority(USART1_
