摘要
IEEE802.15.4是为WPAN设计的一种新兴无线通信协议。网络协调器是协议中定义的一种核心设备,负责一个WPAN的创建、管理、结束。主要介绍了基于主控芯片SEP3203和无线模块CC2420来实现802.15.4无线个域网网络协调器的驱动设计。文中包括系统硬件组成和驱动程序设计两部分。系统硬件组成部分介绍了系统结构及SEP3203与CC2420之间的接口。驱动程序设计部分详细讨论了CC2420和SPI的初始化、数据收发、以及中断服务等程序的设计。
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 he 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.
