The Design Of Handheld Terminal Platform

In recent years, electronic technology, information technology, combining hardware technology embedded technology is developing rapidly. Hand-held terminal equipment in the industrial, military and civilian fields widely used. Based Embedded Development designed a terminal platform and the logistics industry in China and the development trend of information technology demand, the introduction of RFID technology, Design and implementation of logistics-oriented management applications.On the hardware side, based on the functional needs, detailed study of low-level embedded CPU and selection, the core with the necessary interface hardware platform erected on the framework, to choose a YiDao company XSBase255 Development Board, Finally the hardware chart is given. Software, according to embedded system development methodology, First established based on ARM Linux and cross-compiler environment, and then from the bottom to the top development order, against lower hardware boot code transplantation; In the kernel development, analysis of Linux kernel source structure, Hardware functions in the operating system kernel and the reduction related to the driver, Transplantation of MTD , the CS8900A net card, AC97and other driver; introduction of the embedded database, established a data model; Then the application development and porting of them. The database data models into interactive process the data structure to facilitate the procedures for the specific operation; finally, embedded database, application and the necessary order to create a file system, the file system will be transplanted to the platform flash memory.The design of the terminal in improving the efficiency of logistics and reduce logistics costs and the labor intensity and reduce management errors. Finally, the platform for the future expansion of the paper.
