硬件上不需要其他链接，读取的是板子上的stm32的  cpu_id
直接操作寄存器

void setup(){


}

void loop(){

  unsigned int Dev_Serial0, Dev_Serial1, Dev_Serial2;

Dev_Serial0 = *(volatile unsigned  int *)(0x1FFFF7E8);
Dev_Serial1 = *(volatile unsigned int *)(0x1FFFF7EC);
Dev_Serial2 = *(volatile unsigned int *)(0x1FFFF7F0);
  SerialUSB.print(Dev_Serial0,HEX);
  SerialUSB.print("  ");
  SerialUSB.print(Dev_Serial1,HEX);
  SerialUSB.print("  ");
  SerialUSB.println(Dev_Serial2,HEX);
}
