关于9s08dz48的mscan的问题~~请大家指点啊

阿世

 在进行仿真时，出现这句话MSCAN Error - Transmit Buffer #0 not initialized，使程序不能跑起来，请问这是什么原因？
unsigned char cantxdbuffer[8];
void CANTxD(unsigned long id, unsigned short datalen, void *buf) {
    unsigned char *dbuffer = (unsigned char *)buf;
    unsigned short i2 = 0;
  
    if(!CANTFLG){
        return;
    }
    if (datalen > 8) {
        return;
    }
    for (i2 = 0 ; i2 < datalen ; i2 ++) {
        cantxdbuffer[i2] = dbuffer[i2];
    }
    CANTBSEL = 0x01;/* CAN0TFLG; */
    //sel = CANTBSEL;
    CANTIDR0 = (unsigned char)((id >> 24) & 0xFF);
    CANTIDR1 = (unsigned char)((id >> 16) & 0xFF);
    CANTIDR2 = (unsigned char)((id >> 8) & 0xFF);
    CANTIDR3 = (unsigned char)(id & 0xFF);
   
    CANTDSR0 = cantxdbuffer[0];
    CANTDSR1 = cantxdbuffer[1];
    CANTDSR2 = cantxdbuffer[2];
    CANTDSR3 = cantxdbuffer[3];
    CANTDSR4 = cantxdbuffer[4];
    CANTDSR5 = cantxdbuffer[5];
    CANTDSR6 = cantxdbuffer[6];
    CANTDSR7 = cantxdbuffer[7];
   
    CANTDLR = (unsigned char)datalen;
   
    CANTFLG = CANTBSEL;
   
    for ( i2 = 0 ; i2 < 2048 ; i2 ++ ) {
        if ( ( CANTFLG & 0X01) == 1 ) {
            break;
        }
    }
}

没有初始化buffer0

我有一个问题不明白，就是那个通过实参传进来的指针buf赋值给dbuffer指针，然后在程序中就调用数组dbuffer[ ]，这样可以吗？
