Design for Smart Home System Based on Zigbee

Adopt Zigbee to realize the wireless communication of smart home system. Its transceiver module adopts CC2420 as the radio frequency chip. The system uses singlechip PIC18LF4620 as micro controller, which communicates with RF transceiver based on SPI bus and some disperse control signal. Adopt controller (PIC18LF4620) as the SPI master part and RF transceiver as servant part. The controller realizes the IEEE802.15.4MAC layer and Zigbee protocol layer and uses SPI bus to communicate with RF transceiver.
