28377D CAN通讯 可以接收指定ID的数据 不能接收任意其他ID报文

28377D可以，通过CAN盒，接收到下面配置的ID   0x10000008;   的数据

但是CAN盒发送其他ID的数据，则不能收到，

就是只能接收，配置的时候指定的ID的数据，其他ID的数据就不能接到，

和ecan的读取方式区别有点大

下面是部分代码，根据TI的例程改的

#define TX_MSG_OBJ_ID    2
#define RX_MSG_OBJ_ID    1

// Initialize the transmit message object used for sending CAN messages.
 // Message Object Parameters:

     sTXCANMessage.ui32MsgID = 0x10000008;
     sTXCANMessage.ui32MsgIDMask = 0;
     sTXCANMessage.ui32Flags = 0;
     sTXCANMessage.ui32MsgLen = MSG_DATA_LENGTH;
     sTXCANMessage.pucMsgData = txMsgData;

     //
 // Initialize the receive message object used for receiving CAN messages.
 // Message Object Parameters:
 //
 sRXCANMessage.ui32MsgID = 0x10000008;
 sRXCANMessage.ui32MsgIDMask = 0;//0x1fffffff;
 sRXCANMessage.ui32Flags = MSG_OBJ_RX_INT_ENABLE;
 sRXCANMessage.ui32MsgLen = MSG_DATA_LENGTH;
 sRXCANMessage.pucMsgData = rxMsgData;
 CANMessageSet(CANA_BASE, RX_MSG_OBJ_ID, &sRXCANMessage,MSG_OBJ_TYPE_RX);
     // Initialize the transmit message object data buffer to be sent

中断函数---若CAN盒发送的数据ID 为  0x10000008，则可以获取到数据

                   若ID为其他，则不能获取到数据

// 9.5 - CANA Interrupt 1
Void CANA_1_ISR()
{
    // Insert ISR Code here
    Uint32 status;

    status = CANIntStatus(CANA_BASE, CAN_INT_STS_CAUSE);

    // If the cause is a controller status interrupt, then get the status
    if(status == CAN_INT_INT0ID_STATUS)
    {
        status = CANStatusGet(CANA_BASE, CAN_STS_CONTROL);

        // Check to see if an error occurred.
        if(((status  & ~(CAN_ES_RXOK)) != 7) &&
           ((status  & ~(CAN_ES_RXOK)) != 0))
        {
            // Set a flag to indicate some errors may have occurred.
            //errorFlag = 1;
         errorFlag++;//
        }
    }
    // Check if the cause is the CAN-B receive message object 1
    else if(status == RX_MSG_OBJ_ID)   //此处ID为0x10000008则可以读取到数据，其他ID，status就不能触发进到这里
    {
        //
        // Get the received message
        //
        CANMessageGet(CANA_BASE, RX_MSG_OBJ_ID, &sRXCANMessage, true);   
        CANIntClear(CANA_BASE, RX_MSG_OBJ_ID);

    }
    else
    {}

    // Clear the global interrupt flag for the CAN interrupt line
    CANGlobalIntClear(CANA_BASE, CAN_GLB_INT_CANINT0);
    PieCtrlRegs.PIEACK.all = PIEACK_GROUP9;
