.net - .NET 的 Garmin 协议(protocol) GPS 库有哪些

Question

我正在开发一个 GIS 应用程序，并且一直在使用输出 NMEA 协议(protocol)的设备。 NMEA 设备有很多库，但对于 Garmin，我只找到一个，而且不是很完整:OpenGPS.NET

我有两个问题:

1. 如何通过不创建虚拟 com 的 USB 设备使用该库？
2. 还有其他(最好是免费的)Garmin 库吗？

我还使用 Franson GPSgate 将 Garmin 转换为 NMEA，但是当计算机进入休眠模式时出现问题。当它返回时，我必须重置 GPS 设备。

GPS Toolkit.NET可能适合您的需求:

This link to their sample projects显示至少一个示例项目，如下所示:

Garmin Test Panel

The Garmin Test Panel project demonstrates much of the functionality available when using GPS ToolKit.NET with a Garmin GPS using the Garmin protocol. This includes access to position, speed, and direction data, as well as as well as the ability to transfer waypoints, routes, and tracks. You can use this project to test communications with the GPS or to jump start your own project.

The Garmin Test Panel Visual Basic.NET sample project can be found in the Examples\VB\Garmin Test Panel folder.

The Garmin Test Panel C# sample project can be found in the Examples\C#\Garmin Test Panel folder.

The Garmin Test Panel C++ sample project can be found in the Examples\C++\Garmin Test Panel folder.
