基于PDA和GPS OEM板的GPS信息解码

Serial Communication Class Based on Windows CE to Achieve the Serial Communicating of PDA and GPS OEM

研究并开发了一个基于PDA和GPS OEM板的GPS信息解码系统。在Windows CE平台上创建了一个串口通信类来实现PDA和GPS OEM板的串口通信,根据GPS数据的格式创建了相应的GPS数据类,查找数据块头字段和校验码校验来找出完整正确的GPS数据块,通过内存复制的形式进行解析。

First, a serial communication class based on Windows CE was developed to achieve the serial communicating of PDA and GPS OEM. Secondly established some GPS data classes based on GPS message format. Finally, GPS message was decoded by memory copying, after the right GPS message blocks are distilled through seeking GPS message blocks headers and checking according checksum.
