摘要
介绍以51单片机为处理器的应用系统在编程时的内存使用区划分和GPS定位信息流的数据格式。说明GPS15L型接收模块的数据线应用情况。针对51单片机的内存较小和GPS导航数据流较大的矛盾,提出使用51单片机接收GPS数据的一种压缩算法,并给出软件设计流程图,最后以51汇编语言为例给出实际接收GPS数据的部分程序的具体实现方法。
The application system based on processor MCU - 51 is introduced. The system programming memory uses data formats of the division and GPS positioning information flow. The data line application of GPS15L receiver module is noted. Because of the small memory of MCU- 51 and the great navigation data of GPS,a kind of compression algorithm based on the MCU - 51 receiving GPS data is introduced. The flow chart of software design is given. The specific method of the part process for GPS receiving data based on 51 language is given.
