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
