An Embeded Software Customization Of GPS System

With the comprehensive development of electronic technology and its Weeds through the old to bring forth the new, GPS system has improved in a very great degree in aspect of volume, weight, power loss, outward appearance as well as cost and so on . The data-handling capacity become higher and higher, and now it is developing in the direction to the insert the type chip technology being separated from the PC end. Then the more large-scale space information processing can realize. As the core of the inserts type system, the Embeded Operating System is the essential link of the development inserts the type application.This article introduced one kind of GPS system taking the ARM chip as core processor , which matches it to the called Microsoft Windows CE .NET Embeded Operating System software having custom-made. After the brief introduction of the basic principle and its insufficient of existing GPS system, we state the design thought based on ARM and Windows CE inserts type GPS system. In the system of inserts GPS, hardware system taking the ARM chip as the core is the movement platform, and it takes the inserts type Windows CE operating system as the software core which holds the effective resources overall system, simultaneously providing the foundation for the application procedure development. So it holds the important status in the GPS system, therefore this article will conduct the key research on the inserts type Windows CE of GPS system.The paper content includes:First chapter "Introduction" introduces background of this topic as well as each kind of equipment and technical development situation based on GPS and Windows CE application;Second chapter "the Outline of GPS Technology and Inserts Type Operating system" introduces the related GPS technology and the WindowsCE.NET detailed knowledge as well as two unions applications, concrete technical characteristic and technical realization;Third chapter " Introduction of Windows CE Operating system Essence Has custom-made " introduces how has custom-made Windows CE.NET, including environment disposition, as well as concrete disposition step and correlation matters needing attention to and so on;Fourth chapter "Driver and BSP Development" introduced how compiles the driver and the BSP development;Fifth chapter "Partial Application software and Expansion Function Development" introduces some application functions development research, including: The serial communication (USB, blue tooth), the navigation application software synopsis, the application of touching screen and so on;Sixth chapter "Concluding remark" makes the summary to the entire paper, and forecast the future development of ARM chip technology &Windows CE.NET inserts type operating system.
