    CAN.begin(CAN_500KBPS);
}

void loop(){
    CAN.sendMsgBuf(0x00, CAN_STDID, 8, buf);   // Transmit data
                                               // Set remote CAN device ID to 0x00
                                               // Using standard data format
                                               //8 bytes of data
