基于ARM的无线终端系统设计

WIRELESS TERMINAL SYSTEM DESIGN BASED ON ARM

提出了无线数据终端的数据传输模型及技术方案，搭建了以S3C44BOX为控制核心的数据终端硬件平台，完成了外围电路及GPRS射频模块设计。同时，在软件方面实现了嵌入式实时操作系统μC／OS-Ⅱ和轻型TCP／IP协议栈（LwIP）的移植用以满足基于GPRS的无线数据传输上层应用。

Put out the transmission model and technological scheme about wireless data terminal, build the hardware platform which dominant core is S3C44BOX, accomplished the periphery circuit and GPRS mode. At the same time, in the software, realized transplant of μC/OS-Ⅱ and the light weight TCP/IP（LwIP） in order to fit the application of wireless data transmission based on GPRS.
