摘要
分析了ZigBee的特点,指出了以ARM-Linux嵌入式系统与CC2420组合作为ZigBee网络中的全功能节点的特有优势。阐述了芯片工作原理与硬件系统组成方式,并且给出了CC2420与ARM底层通信机制SPI驱动设计的方法,使得CC2420与系统间的数据交换得到保证,同时也是上层应用的基础。
In this paper, the feature of ZigBee is analyzed. The advantage of ARM-Linux embedded system with CC2420 by way of FFD is expounded. The work principle of the chip and hardware platform has been discussed in detail. A SPI driver design method has been present to fulfill the data exchanging between processor and CC2420, for the more, it is also the assurance of the application.
