征服stm32 can 标准帧 扩展帧 过滤器配置

如果过滤器配置不好，就会导致发送的数据接收不到，下面是过滤器配置的代码

//配置过滤器

CAN_FilterInitStructure.CAN_FilterNumber=0;   //过滤器0

CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdMask; 

CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit; //32位 

/*******************************标准帧配置***********************************

#define   ID_REQUEST                          0xc750        //11000 11101010 000

#define   Mask_Ack_Request_Tbdt               0xffc0

********************************************************************/

CAN_FilterInitStructure.CAN_FilterIdHigh=ID_REQUEST;////32位ID

CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;

CAN_FilterInitStructure.CAN_FilterMaskIdHigh=Mask_Ack_Request_Tbdt;//32位MASK

CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;

/*******************************标准帧配置***********************************

CAN_FilterInitStructure.CAN_FilterIdHigh=0x0000;////32位ID

CAN_FilterInitStructure.CAN_FilterIdLow=0x0000;

CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0x0000;//32位MASK

CAN_FilterInitStructure.CAN_FilterMaskIdLow=0x0000;

*******************************************************************/

CAN_FilterInitStructure.CAN_FilterFIFOAssignment=CAN_Filter_FIFO0;//过滤器0关联到FIFO0

CAN_FilterInitStructure.CAN_FilterActivation=ENABLE; //激活过滤器

CAN_FilterInit(&CAN_FilterInitStructure);//滤波器初始化
