怎么个不行，不妨你把你的程序发给我，我帮你看看，

if (HAL_FDCAN_Init(&FDCAN1_Handler) != HAL_OK)
{
//ERROR_HANDLER(); /* 出错处理 */
}
else
{
/* nothing */
}

   /* 配置接收滤波器 */
   sFilterConfig.IdType = FDCAN_EXTENDED_ID;
   sFilterConfig.FilterIndex= 1;
   sFilterConfig.FilterType = FDCAN_FILTER_MASK;
   sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
   sFilterConfig.FilterID1 = 0xFFF11000U;
   sFilterConfig.FilterID2 = 0xFFFFE000U;
   HAL_FDCAN_ConfigFilter(&FDCAN1_Handler, &sFilterConfig);

/* 启动FDCAN */
if (HAL_OK != HAL_FDCAN_Start(&FDCAN1_Handler))
{
//ERROR_HANDLER(); /* 出错处理 */
}
else
{
/* nothing */
}

/* 使能接收FIFO New Message中断 */
if (HAL_OK != HAL_FDCAN_ActivateNotification(&FDCAN1_Handler, FDCAN_IT_RX_FIFO0_NEW_MESSAGE, 0U))
{
// ERROR_HANDLER(); /* 出错处理 */
}
else
{
   /* nothing */
}

/* 使能发送FIFO Empty中断 */
if (HAL_OK != HAL_FDCAN_ActivateNotification(&FDCAN1_Handler, FDCAN_IT_TX_FIFO_EMPTY, 0U))
{
// ERROR_HANDLER(); /* 出错处理 */
}
else
{
   /* nothing */
}

return 0;
}
公司的文件是加密，这是我的配置，请你给看看对不对

只能收发15个数据啊。。。

u8 BspMcuCanInit(void)
{
FDCAN_FilterTypeDef sFilterConfig;

缺少这个函数，全局滤波设置没有这个函数，总线上任何数据你都能收到。

按照你的方法还是收到全部数据

shouhong829 发表于 2019-1-24 16:03:34

能发送数据，但滤波数据不行大家看看那里不对了

oujisang 发表于 2019-1-24 19:28:34

HAL_FDCAN_ConfigGlobalFilter(&FDCAN1_Handler, FDCAN_ACCEPT_IN_RX_FIFO0, FDCAN_ACCEPT_IN_RX_FIFO0, ENABLE, ENABLE);

不要用“FDCAN_ACCEPT_IN_RX_FIFO0”这个参量，这个是标识没有匹配到要滤波的ID就放到FIFO里了要改用“FDCAN_REJECT”参量，没有匹配到滤波的ID就拒绝接收

HAL_FDCAN_ConfigGlobalFilter(&hfdcan1, FDCAN_REJECT, FDCAN_REJECT, ENABLE, ENABLE)
