求救啊，关于zet6 CAN1 CAN2的使用

寒潮 · 发表于 2015-6-2 16:59:25

原子哥，我用的是stm32f103zet6，战舰板。想用两个CAN接口，能不能这样用啊：CAN1用的是PA11、PA12。CAN2用的是引脚复用，PB8、PB9。复用的是CAN2，但好像找不到CAN2的中断函数名啊，实验的时候，CAN1能正常收数据，CAN2好像进不了中断，也没收到数据…………
还有就是f103zet6里主CAN（CAN1）和从CAN（CAN2）有什么区别啊，还是它根本没有CAN2呢？
互联型的有两个CAN接口，但我现在手里只有f103zet6啊，上面的方法不可行的话，还有什么办法没有呢？
先谢谢啦
各位大神也帮小弟我看看吧，不胜感激
