Hi,
Somebody can help me how to make an NMEA generating hardware sample?

How to create an NMEA sentence?
Which program chip need to use and how?
Can i get some sample circuits for my project?

Best regards

推荐答案

您需要一台支持所需硬件接口的设备使用NMEA版本（EIA-422或EIA-232与 NMEA 183 [ ^ ]和带有的CAN总线NMEA 2000 [ ^ ]）。



使用EIA-422和EIA-232，您可以使用任何支持串行通信的微控制器，通过连接适当的接口芯片进行电平转换和隔离到串行端口。只需搜索EIA-422驱动程序ic或EIA-232驱动程序ic。



请参阅上述维基百科的协议链接（如何创建NMEA句子） 。



使用哪种设备取决于要执行的任务和界面。如果您想实施NMEA 2000，请选择带有集成CAN总线接口的微控制器。



基本采样电路由使用过的IC制造商提供。

You need a device that supports the hardware interface required by the used NMEA version (EIA-422 or EIA-232 with NMEA 183[^] and CAN Bus with NMEA 2000[^]).

With EIA-422 and EIA-232 you can use any micro controller that supports serial communications by connecting appropriate interface chips for level shifting and isolation to the serial port. Just search for "EIA-422 driver ic" or "EIA-232 driver ic".

See the above Wikipedia links for the protocols (how to create NMEA sentences).

Which device to use depends on the tasks to be performed and the interface. If you want to implement NMEA 2000 choose a micro controller with integrated CAN Bus interface.

Basic sample circuits are provided by the manufacturers of the used ICs.
