Design Of Short Distance Wireless Communicating System Based On WINCE

With the rapid development of computer technology, many kinds of computer devices, especially embedded devices, are applied in many aspects of our life. On one hand, people are enjoying the convenience brought by the computer devices; On the other hand, more and more people become aware of that it is really a compressing problem to solve the communication among different devices.Now most devices are connected by cable. However, it is very uneasy to connect some devices in special circumstance. Therefore, we hope to take the way of wireless connection instead of cable. In this thesis, RF technology is used to implement wireless connection. Over the wireless network, embedded systems transfer information to other systems, and a lot of cables are replaced with wireless.The main part of this thesis is to implement the communication between receiving/transmitting chips based on nRF401, one of the communication ends is client information system using MCU as core, the other one is terminal device that can operate information using ARM9s3c2440 as core and WINCE as embedded operating system. The main important research is how to design hardware and software of the embedded system and how to design system based on MCU. About hardware design, we mainly finish the interface connecting ARM with the serial and SPI interface of MCU. About software design, we mainly finish making BootLoader, selecting WINCE component, and modifying stream interface driver. We also code interface of serial by EVC. In the end, we test the whole system, the result shows that all the hardware works well and the software acts as expected.
