STM32 CAN过滤器设置列表模式有问题？

紫阳真人

  有4个帧ID，所以设置了列表模式，发现只有0x0040和0x07F8两个报文能收到，另外两个收不到，不知道原因。
下面是代码配置：
sFilterConfig.FilterNumber = 0;
  sFilterConfig.FilterMode = CAN_FILTERMODE_IDLIST;
  sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT;
  sFilterConfig.FilterIdHigh = (0x07FF << 5);
  sFilterConfig.FilterIdLow = 0x07FF;
  sFilterConfig.FilterMaskIdHigh = (0x07FE << 5);
  sFilterConfig.FilterMaskIdLow = 0x07FE;
  sFilterConfig.FilterFIFOAssignment = 0;
  sFilterConfig.FilterActivation = ENABLE;
  sFilterConfig.BankNumber = 14;
  HAL_CAN_ConfigFilter(&hcan, &sFilterConfig);
       
        sFilterConfig.FilterNumber = 1;
  sFilterConfig.FilterMode = CAN_FILTERMODE_IDLIST;
  sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT;
  sFilterConfig.FilterIdHigh = (0x07F8 << 5);
  sFilterConfig.FilterIdLow = 0x07F8;
  sFilterConfig.FilterMaskIdHigh = (0x0040 << 5);
  sFilterConfig.FilterMaskIdLow = 0x0040;
  sFilterConfig.FilterFIFOAssignment = 0;
  sFilterConfig.FilterActivation = ENABLE;
  sFilterConfig.BankNumber = 14;
  HAL_CAN_ConfigFilter(&hcan, &sFilterConfig);

  HAL_CAN_ConfigFilter(&hcan, &sFilterConfig);


列表模式下，只有收到设置了相同ID（0x0040和0x07F8）报文才能收到

4个帧ID 如果是连着的，最好用 标识符屏蔽模式
