(With the rapid development of ZigBee technology, ZigBee wireless communication network has been continuously used in smart homes. The architecture of ZigBee protocol is briefly introduced, and a ZigBee wireless communication network node composed of MSP430 microcontroller and CC2420 radio frequency chip is designed. The hardware structure of nodes and nodes and the software process of participating in the network are analyzed, and the network topology of multiple nodes and nodes is discussed in detail.)
