摘要

 點對點無線數據通信是一基本的通信方式，在無線傳感器、無線數傳系統等許多系統中可以廣泛的引用。CC1100是Chipcon公司研制的一款可用于多頻點的短距離無線數據通信收發模塊,具有性能好,應用簡便的優點.在電子消費產品、無線警報和安全系統、無線傳感器網絡等許多領域中都有廣闊的應用。
 本課題選擇內置Flash的Philips P89LPC935微控制器，采用點對點數據通信模式，驅動信號調制頻率定于433MHz 的CC1100無線收發模塊。本設計面向低成本無線數據通信，利用無線擴頻收發模塊，由MCU驅動。可以繼續升級，如多點通信，組網通信。 課題工作包括了解無線數據通信機制和無線局域網標準，掌握和使用CC1100，掌握P89LPC935及其開發工具；設計和制作基于P89LPC935、RTC、RS232等芯片和CC1100模塊的基本系統；擴展I2C總線、SPI總線和UART接口，開發運行于該系統的驅動程序。
 本系統系統板具有較好的適用性, 可以作為工作在2.4GHz越障性能差的低速無線數據接入或PAN網絡節點的一種補充。進一步的完善設計使系統支持多點通信。

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
