Design And Realization Of Vehicle Terminal's GUI Based On Embedded Linux

Along with the develope of informatization, the vehicle terminal based on GPS has a good forground in our native. This article mainly introduces the realization of vehicle terminal system based on embedded Linux OS (operating system) and software platform with Graphics User Interface ------MiniGUI.At first it simply introduces vehicle terminal's developing situation, the functions and realizations of GPS modules and GPRS modules, the product's developing document aimed at vehicle terminal's design. It selects and deeply investigates embedded Linux OS, detailed describes embedded Linux OS's characters,the process of compile and replant, as well as deeply investigates other software and function modules just as Bootloader, File System and so on.then, combined with the applications in embedded system and the characters of graphics user software— MiniGUI, it puts forward the way to design and realize vehicle terminal's GUI.During the realizing process, it has maturely considered the characters that embedded OS have responded quickly, occupied little memory in computer, and it try its best to reduce product's cost, increase product' effect, guarantee product's characters, such as realizing fullfunctions, have more capability with low cost.Finally, it puts forward the prospect of next generation vehicle terminal system's developing direction.
