求助各位高手,STM32F107RC的CAN不能发送数据，我用的振晶是8M的，CAN1发送是第A端口11脚，接收是A端口12脚，现在我没有发现错误，就是不能发送回来，求求各看看是什么原因，

现在我没有发现错误，就是不能发送数据，求求各看看是什么原因，
/**

各位看看是什么原因啊，每次都是这些问题，真不知道怎样查啊，

请检查频率设置的是否匹配。
CAN_InitStructure.CAN_SJW = CAN_SJW_1tq;
CAN_InitStructure.CAN_BS1 = CAN_BS1_3tq;
CAN_InitStructure.CAN_BS2 = CAN_BS2_5tq;

那肯定是配置的问题。
