The Development Of The Driver Of Wireless Net Work Card And The Usb Interface Based Under The Embedded Linux System

The project needs to transform the data collected by the gyroscope through the wireless net work card to control the intersection angle and the obliquity to maintain the balance of the bicycle robot. The wireless net work card is the instrument of the terminal wireless network, it is used under the cover of the wireless net work to connect the wireless instrument. At the same time the data collected should be saved through the USB interface for the further use. For example emulation. So the project is mainly two parts, the first is the development of the driver of USB based under the embedded system, the second is the development of the wireless net card under the embedded system.Because the Linux system provide all the source code and implicated commitment file for free so the project chose it as the embedded operation system and successfully installed the soft and hard ware system. At the same time application of the technology of USB and the transformation of the wireless net work more and more widely, the study of the embedded technology is becoming a hot pot of this area and the products based under the embedded platform is becoming more and more. The paper give a implicated analysis and instrument for both of the above two parts. Give a really implicated instrument of the principle of the USB interface and the wireless network card and analysis the problem and answer through out the project. So get a further understand of the development of the driver of the USB and wireless net work card.
