办法很简单,将"CAN_H"与"CAN_L"直接短接,然后让其发送数据,正常情况下,就会触发错误中断了,发送错 误寄存器会瞬间加至"128",如果继续发,每发一次,发送错误计数器会+8,直到256,然后CAN节点即会进入离 线状态,也就是"Bus off"状态)。 一步一步查,才发现,"CAN1_SCE_IRQn"的M3内核中断没有开,也就是NVIC...

一步一步查,才发现,"CAN1_SCE_IRQn"的M3内核中断没有开,也就是NVIC相关配置。对于NVIC还真没太明 白,幸好有老司机左栋在。( 虽然对这个称谓他还是是拒绝的:) )跟左栋学了很多,非常感谢。 二、正文 对于NVIC(Nested Vectored Interrupt Controller),中文一般翻译为嵌套向量中断控制器, 其为M3内核层次概念,相...
