摘要： A single wire serial communication method and single wire serial communication system are disclosed. In every communication, the master device transmits a data packet, and each of the plurality of slave devices sequentially receives the data packet. The slave device forwards the data packet to a next slave device, and before the data packet are forwarded to the next slave device, the slave device modifies device address data in the data packet. The slave device compares the device address data in the received data packet with preset data or the device address data transmitted by the master device in order to find at least one target slave device in the communication. The single wire serial communication method and the single wire serial communication system solves a problem of automatic addressing of single wire serial communication of a plurality of same apparatus without performing address initialization, thereby avoiding all communication on the latter stage from influencing due to the failure of the address initialization.

摘要： A single-wire communication method and a single-wire communication system are disclosed. The single-wire communication system sequentially performs address coding on a plurality of slave devices according to the positions of the plurality of slave devices in a communication link, and a master device sequentially finish the address coding of all of the plurality of slave devices by transmitting an addressing command. And when data broadcasting or call transmission is performed on the latter stage, the communication of the master device and each of the plurality of slave devices may be implemented by inserting corresponding address data into the coding command.

摘要： A communication system and a communication method are disclosed. The communication system includes a master device (Master) and at least two communication channels (MD01 - MD04). Each communication channel includes at least one serially connected chip (IC(1,1)- IC(4,1)). Each chip includes a communication input pin (SDI), a communication output pin (SDO), and at least one addressing pin (ADDR). The first chip (IC(1,1)- IC(4,1)) in each communication channel is connected to the corresponding output port (MD01 - MD04) of the master device. The connection of the addressing pin in the chip includes one of floating, coupling to the communication input pin of the chip and coupling to the communication output pin of the chip. The master device distinguishes each communication channel according to the connection of the addressing pin of at least one first chip in each communication channel. The communication system saves the port resources of the master device.
