pubdate：2018/06/20 16:25:00 posted by： visit times：440
Any master can send data to the specified slave. Only the specified slave can receive and output data. The other slaves have no output. Any slave sends data, and only the corresponding master receives and outputs the data. The slave data is completely transparent whether it is received or sent. Easy to use, it is suitable for applications where one or more parallel masters communicate with multiple slaves.
