Driver Design for Coordinator in 802.15.4 WPAN

The standard of IEEE 802.15.4 is a new wireless communication protocol designed for WPAN.A coordinator is the key device defined in the protocol.It can be used to create,manage,and destroy a WPAN.This paper introduces the driver design for coordinator in 802.15.4 WPAN based on a main controller SEP3203 and a wireless unit CC2420.It includes two parts:the system hardware components and the driver design.The part of system hardware components is about the system architecture and the interface between SEP3203 and CC2420.The part of driver design is about the design of initialization of CC2420 and SPI,transmitting/receiving data and the ISR.
