keil5编译,想要用CAN接收中断接收数据,出现"USB_LP_CAN1_RX0_IRQn" has already been declared in the current scope,请问大佬们怎么解决。 https://bbs.csdn.net/topics/399174194?list=3933356

如果把只初始化了USB_LP_CAN1_RX0_IRQn中断向量,则所有的正确传输中断只会进入USB_LP_CAN1_RX0_IRQHandler->CTR_LP,所以要想进入CTR_HP必须对其中断向量进行初始化,否则会使用默认的CTR_LP路径进行处理。打开APP阅读更多精彩内容 声明:本文内容及配图由入驻作者撰写或者入驻合作网站授权转载。文章观点仅代表作者本...
