The Design And Implementation Of Embedded Handhold Terminal Based On GPRS And μC/OS Ⅱ

Based on the researching background of handhold terminal and adopting the embedded settlement scheme based on GPRS network and RTOSμC/OS-II,this paper discusses the designment,implementation and extended function of embedded handhold terminal based on GPRS network and real-time operating system.The paper elaborates the embedded handhold terminal's hardware and software system's designments.Throughing reasonable separation of hardware and software and designing good software architecture handhold terminal can conveniently arrange applications of other types. The application domain of the handhold terminal can also be extended accordingly.Finally, by testing the system with GPS application, it validates the expansibility and the ability of second development of the handhold terminal based on GPRS network and RTOS.
