can使能后发送数据，如果can总线上没有其他节点接收数据，单片机直接重启。接上接收设备后，单片机正常工作。can配置代码如下 //CAN Config static void App_CANCfg(void) { stc_can_init_t stcCanInit; /************************* Configure CAN1***************************/ stc_can_filter_config_t astcFilter1[1U] = { {0x1UL, 0x0000UL, CAN_ID_STD}, }; /* Initializes CAN. */ (void)CAN_StructInit(&stcCanInit); stcCanInit.stcBitCfg.u32Prescaler = 12U; stcCanInit.stcBitCfg.u32TimeSeg1 = 5U; stcCanInit.stcBitCfg.u32TimeSeg2 = 3; stcCanInit.stcBitCfg.u32SJW = 3; stcCanInit.pstcFilter = astcFilter1; stcCanInit.u16FilterSelect = CAN_FILTER1; stcCanInit.u8WorkMode = CAN_WORK_MD_NORMAL;//CAN_WORK_MD_ELB; stcCanInit.u8PTBSingleShotTx = CAN_PTB_SINGLESHOT_TX_ENABLE; stcCanInit.u8STBSingleShotTx = CAN_STB_SINGLESHOT_TX_ENABLE; stcCanInit.u8STBPrioMode = CAN_STB_PRIO_MD_DISABLE; stcCanInit.u8RxWarnLimit = 10U; stcCanInit.u8ErrorWarnLimit = 15U; stcCanInit.u8RxAllFrame = CAN_RX_ALL_FRAME_DISABLE; stcCanInit.u8RxOvfMode = CAN_RX_OVF_DISCARD_NEW; stcCanInit.u8SelfAck = CAN_SELF_ACK_DISABLE; /* Enable peripheral clock of CAN. */ FCG_Fcg1PeriphClockCmd(FCG1_PERIPH_CAN, ENABLE); (void)CAN_Init(CM_CAN, &stcCanInit); CAN_ExitLocalReset(CM_CAN); /* Enable the interrupts, the status flags can be read. */ CAN_IntCmd(CM_CAN, CAN_INT_ALL, DISABLE); CAN_IntCmd(CM_CAN, CAN_INT_ERR_INT|CAN_INT_RX_BUF_WARN|CAN_INT_RX|CAN_INT_BUS_ERR, ENABLE); }

MSPM0的板子的CAN是CAN-FD，怎么配置成经典CAN控制3508电机

CAN的扩展帧ID和数据帧都要进行大小端的转换吗？如帧ID是０ｘ１２３４５６７８ 是不是要转成０ｘ７８５６３４１２ 那么８位帧数据呢？ 如０１　２３　４５　６７　８９　ＡＢ　ＣＤ　ＥＦ 是不是要转成 　ＥＦ　ＣＤ　ＡＢ　８９　６７　４５　２３　０１ 求指教？

参考官方例程communication_FDmode，CAN1_TX只会出现一两个低脉冲。直接用例程去掉按键、加个50ms延时周期发送也是一样的波形.

诸位兄弟姐们打扰了，最近在测试GD32e103的can功能， 根据资料范例程序和网上相关帖子测试程序收发均有问题， 希望哪位兄弟有成功经验的能够传授一下，甚是感谢！！！

请教各位：GD32的CAN中断中，除了发送、接收中断，还有一个比较特殊的EWMC中断。请问这个中断是起什么作用的呢？

最近使用GD32E103的can，使用的1.0.0的固件库发现在CAN和CANFD混用的时候相关操作函数有些BUG，然后下载了1.2.0的库发现can相关的东西完全没有了

各位大神， 请问怎么在广播里面广播出mac地址？ 我自己的想法是，先获取到mac地址，再把mac地址添加到scanRspData[]中？ 但是我在使用GAPRole_GetParameter的时候，在蓝牙状态改变的回调函数中可以正常使用，在其他地方就不行。 请问还有什么方法可以获取吗？

STM32F103 64引脚，CAN程序在环回模式下好用，但改成正常模式下不好用，不知道还注意些什么
