Design And Realization Of BSP About The GPS Vehicle Navigation System Based On WinCE.NET

In recent years,with the popularization of cars and the construction of roads,the economical intercourse of city become more frequent and the region of area that people moved is broader than ever,which produce many serious problems such as traffic jam,diffculty of destination find, lower efficiency and so on.GPS vehicle navigation system can effectively improve those problems and bring convinent service to people.It will become the basic equipment of our vehicle.Nowadays,the GPS vehicle navigation system's development is comparatively fall behind in native. Occording to the reaserching condition of our own, while by terms of the merit of products now available, The developing of BSP that plays an key and base role in the chinese circumstance in GPS vechile navigation system based on the platform of ARM and Wince.NET,.From it, we can find sertain theory mean and adaptive value in realization both.GPS vehicle navigation system concerns to widespread technique field. This article point to the advanced embedded system technique, basing on the platform of Microsoft's WinCE.NET and SHARP's LH7A404, designing and realizing the system platform's board support package(BSP). It is the base and key to realize the system kernel transpaltation as well as the appliance software of whole system. At first, we design the whole system to confirm the system components of software and hardware. Then, custom operating system kernel and analyses the BSP architecture and developing steps of software parts. Follows that, detailed developing system loader program Boot Loader and others parts of OAL. Finally,it concludes the implementation of model for the devices driver,including interrupt analyzing of the mechanism and loading mechanism of device driver.the SD memory card driver program is mainly researched and developed。This work which introduced by the article is applied to the design of the GPS vehicle navigation system of a company in Shenzhen, furthermore,its'product have been launched to market at home, and gain the great economic benefits.
