Research Of Gprs System Based On Arm And Linux

A set of GPRS communication system is designed in this thesis.The system based on uclinux and ARM. A development evaluation board is named Guangzhou Zhiyuan ZLG_Magic2200 and BenQ GSM/GPRS module M32 have been used to the system.LPC2210 processor is used for hardware platform,then, ported Linux on this processor OS. Using MiniGUI that a figure development environment to come ture interface design of system.The system have functions that GPRS receive SMS and send SMS and phone somebody,and so on.Embedded Linux is an operation system which is cut off and modified from common Linux, and which can run on embedded computer system. Now days the ARM(Advanced RISC Machine) is a mainstream CPU architecture for embedded system and have been used broadly. Therefore the developers play a special emphases at porting linux kernel to ARM CPU. In this background, we integrated embedded system and embedded Linux technology together and architected embedded uClinux system based on ARM7TDMI core microprocessor. As a part of an embedded system, bootloader, some device driver programs and application programs are amended and designed.GUI (Graphical User Interfaces) systems which are supported by normal PCs can not run well on the embedded systems, just because of the restriction of embedded devices' hardwares. I select MiniGUI as my research object.Based on the MiniGUI architecture and its other aspects, the technique of porting MiniGUI to board is given in detail.
