YTM32B1ME0 CAN通讯过滤器配置问题

参照SDK应用_FlexCAN模块配置及应用（二）.pdf文档如何配置过滤一段标准帧和一段扩展帧呢？

按照这种配置标准帧会出现不是过滤列表的ID数据被接收回来，是哪里配置不对呢？麻烦帮忙看一下，谢谢

你要过滤哪些ID,或者说你哪个ID你认为被误过滤了，可以详细说一下，这样比较好帮忙定位你的问题

const flexcan_id_table_t can_filter_table[16] =
{
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x370, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x380, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x242, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x634, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x789, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x480, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x408, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x409, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x703, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x704, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = true, /!< Extended frame/
.id = 0x14f0a0b0, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = true, /!< Extended frame/
.id = 0x0c33a0b0, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = true, /!< Extended frame/
.id = 0x1888a0b0, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = true, /!< Extended frame/
.id = 0x1f002100, /!< Rx FIFO ID filter element/
},
{
.isRemoteFrame = false, /!< Remote frame/
.isExtendedFrame = false, /!< Extended frame/
.id = 0x1f0, /!< Rx FIFO ID filter element/
},
};
其中0x370是0x370~0x37f；0x1f002100是0x1fxx2100都接收；按照目前的配置ID为0，8，9，80，500~540这些都会被收进来

使用独立掩码且使用FORMAT_A，需要每个接收码都设置掩码，可以参考这个帖子：https://forum.ytmicro.com/topic/586/有无任意开发板的flexcan_legacyfifo的flexcan_rx_fifo_id_format_b模式和flexcan_rx_fifo_id_format_c模式例程或代码片段?_=1754043294102

1_3_1版本及以前的SDK参照如图所示手动修改一下
