摘要
简单介绍了GPS接收机串口通信的基本概念和GPS数据输出的格式。主要论述了如何用多线程编程方法在W indows CE下实现GPS接收机与PDA的通信,以及线程间的数据通信,线程调度,数据同步等问题。
The basic concept and output data format of GPS receiver＇s serial communications were simply introduced. The paper described how to communicate between GPS receiver and PDA with muhithreaded programming based on Windows CE. Meanwhile some issues such as communicating and synchronization between threads were discussed.
