  • HC32F460的CAN出现CAN_FLAG_TEC_REC_WARN错误

    目前CAN波特路设置为125k,用200米的线进行通讯时出现CAN_FLAG_TEC_REC_WARN这个错误,有人知道怎么回事吗?

  • HC32F460 CAN通讯问题

    我在调试HC32F460的CAN通讯时发现如果同时收到了两帧数据,第二帧数据会保存下来,导致下面接收的数据是上一帧的数据,然后后面的接收都错位了,中断里也清标志位了,有人指导一下吗?我的初始化及中断接收处理如下:[code]staticvoidCanInitConfig(uint16_tCAN_Baud_Rate){stc_can_init_config_tstcCanInitCfg;stc_can_filter_tastcFilters[CAN_FILTERS_COUNT]=\{{0x00000000ul,0x111ul,CanFilterSel1,CanAllFrames}};//
