基于eVB的Comm控件的GPS通信的实现

The Implementation of GPS with the Comm Control based on eVB

在众多领域中,GPS技术被广泛的运用。本文阐述了在WindowsCE3.0嵌入式系统中,利用Comm(MicrosoftCECommControl)控件实现GPS接收机与PocketPC之间串口的通信方法。首先介绍了GPS输出的数据格式,并对GPS通讯技术做了相应的描述;接着详细说明了Comm控件的运用,并基于eVB3.0(MicrosofteMbeddedVisualBasic3.0)给出具体步骤和部分实现代码;最后讨论了GPS通信中应注意的问题。

GPS technique is abroad applied in multitudinous fields. This paper discusses the technique about serial port communication between GPS and Pocket PC with Comm （Microsoft CE Comm Control） based on Windows CE 3.0. First, the output date format of GPS is presented as well as the description about its＇ communication technique; Then it describes the application of the Comm control, the steps of realization and part of codes based on eVB3.0 （Microsoft embedded Visual Basic 3.0） are also given; At last, it discusses the questions about the communication of GP.
