摘要

 点对点无线数据通信是一基本的通信方式，在无线传感器、无线数传系统等许多系统中可以广泛的引用。CC1100是Chipcon公司研制的一款可用于多频点的短距离无线数据通信收发模块,具有性能好,应用简便的优点.在电子消费产品、无线警报和安全系统、无线传感器网络等许多领域中都有广阔的应用。
 本课题选择内置Flash的Philips P89LPC935微控制器，采用点对点数据通信模式，驱动信号调制频率定于433MHz 的CC1100无线收发模块。本设计面向低成本无线数据通信，利用无线扩频收发模块，由MCU驱动。可以继续升级，如多点通信，组网通信。 课题工作包括了解无线数据通信机制和无线局域网标准，掌握和使用CC1100，掌握P89LPC935及其开发工具；设计和制作基于P89LPC935、RTC、RS232等芯片和CC1100模块的基本系统；扩展I2C总线、SPI总线和UART接口，开发运行于该系统的驱动程序。
 本系统系统板具有较好的适用性, 可以作为工作在2.4GHz越障性能差的低速无线数据接入或PAN网络节点的一种补充。进一步的完善设计使系统支持多点通信。

ABSTRACT

 Point-to-point wireless date traffic is a basic method of correspondence, it has been widely used in many systems, such as in wireless transducer, wireless date traffic system and so on.  CC1100 is studied by Chipcon, characterized by its good function and easy usage, can be used as a module, which is applied in frequent wireless date sending. Especially in electronic consumable, wireless alarm, safe system, wireless transducer and so on.
 This paper chooses inner flash of Philips P89LPC935 controller, adopts Point-to-point mode, to drive modulated signal be fixed in 433MHz of CC1100 wireless receiving mode. The design mainly faces to lower cost wireless date correspondence, and uses wireless expanded frequency receiving mode and is drive by MCU. It can be updated, like point correspondence and net correspondence. The main task for this subject is to know the wireless date traffic system and the standard of wireless local area network, to use cc1100, P89LPC935 as well as their tool, to design and make chip based on P89LPC935、RTC、RS232, and basic system of CC1100, to enlarge I2C general line, SPI general line and UART, which are used in driver.
 This board can be used as complement with its good applicability, which is used in meeting low-speed wireless when works in 2.4GHz. And make the design perfect to support point-to-point communicate
