求助：FDCAN 不管手工写，还是cube 配置，都不能使用，norminal = 500K，Data = 2M；
参考了：https://www.armbbs.cn/forum.php?mod=viewthread&tid=109353
芯片：H743；时钟选 HSE 12M；
配置
也使能了代码；
- sFilterConfig.IdType = FDCAN_STANDARD_ID;
- sFilterConfig.FilterIndex = 0;
- sFilterConfig.FilterType = FDCAN_FILTER_MASK;
- sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
- sFilterConfig.FilterID1 = 0x111;
- sFilterConfig.FilterID2 = 0x7ff;
- HAL_FDCAN_ConfigFilter(&hfdcan1, &sFilterConfig);
- HAL_FDCAN_ConfigFilter(&hfdcan2, &sFilterConfig);
- sFilterConfig.IdType = FDCAN_STANDARD_ID;
- sFilterConfig.FilterIndex = 1;
- sFilterConfig.FilterType = FDCAN_FILTER_MASK;
- sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
- sFilterConfig.FilterID1 = 0x222;
- sFilterConfig.FilterID2 = 0x7ff;
- HAL_FDCAN_ConfigFilter(&hfdcan1, &sFilterConfig);
- HAL_FDCAN_ConfigFilter(&hfdcan2, &sFilterConfig);
- sFilterConfig.IdType = FDCAN_STANDARD_ID;
- sFilterConfig.FilterIndex = 2;
- sFilterConfig.FilterType = FDCAN_FILTER_MASK;
- sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
- sFilterConfig.FilterID1 = 0x333;
- sFilterConfig.FilterID2 = 0x7ff;
- HAL_FDCAN_ConfigFilter(&hfdcan1, &sFilterConfig);
- HAL_FDCAN_ConfigFilter(&hfdcan2, &sFilterConfig);
- HAL_FDCAN_ConfigGlobalFilter(&hfdcan1, FDCAN_REJECT, FDCAN_REJECT, FDCAN_FILTER_REMOTE, FDCAN_FILTER_REMOTE);
- HAL_FDCAN_ActivateNotification(&hfdcan1, FDCAN_IT_RX_FIFO0_NEW_MESSAGE, 0);
- HAL_FDCAN_Start(&hfdcan1);
- HAL_FDCAN_ConfigGlobalFilter(&hfdcan2, FDCAN_REJECT, FDCAN_REJECT, FDCAN_FILTER_REMOTE, FDCAN_FILTER_REMOTE);
- HAL_FDCAN_ActivateNotification(&hfdcan2, FDCAN_IT_RX_FIFO0_NEW_MESSAGE, 0);
- HAL_FDCAN_Start(&hfdcan2);
