NMEA Converter
#1
I use Open CPN on Windows with the NMEA Converter just fine.  I have installed Open Plotter on Raspberry Pi with no problem.  How can I install the NMEA Converter onto my Rasb Pi?  I am using the plugin for R&D on our new electromagnetic FWD and LEE velocity transducer.    Any help would be greatly appreciated.  

Thanks!

Thanks for the quick response and link. When I look at my menu; Tools.. There is no option for NMEA Generator. My goal is to take specific fields out of GPGLL, GPVTG, HDHDT, and VMVBW. From there, I create a custom NMEA sentence with just the fields I want. Direct ocean current readings are calculated in real time from the data. Hopefully I can do this in Open Plotter and get away from a Windows machine with Open CPN.

Our electromagnetic transducer measures both FWD and LEE directly with boat angle calculated from these two values. With COG, SOG, and HDG data, we can calculate currents. http://www.brickhouseinnovations.com

BTW: This link (toward the bottom of the page) is where I saw the NMEA Converter plugin working with OpenPlotter / Raspberry pi. https://opencpn.org/wiki/dokuwiki/doku.p..._converter

I know extremely little about Raspberry Pi and would love to be able to drop in the NMEA converter plugin. I just cant find the file or install.

I think on linux you have to compile that plugin, don't think there's a simple download. Compiling is a bit involved if you're new to it. 

There is a similar program in openplotter itself,  in the tools menu on the openplotter main setup window. It can create nmea sentences from signalk data o if you can see it in the signalk inspector you should be able to create the nmea you wawnt from there though limited to the sentences available in the dropdown list.

This plugin now builds out of the OpenCPN source tree
git clone git://github.com/RooieDirk/NmeaConverter_pi.git
###Build:

mkdir NmeaConverter_pi/build
cd NmeaConverter_pi/build
cmake ..
cmake --build .

or check this on the pi ip adress

Thanks and I did try that.  Ran through the above steps and Configuring is Incomplete. errors occurred.   See Picture... https://drive.google.com/file/d/1j3DsEz6...sp=sharing

Looks like you have to compile the whole of opencpn ->

Might be much easier to use the NMEA converter built into Openplotter.

I am looking into that PaddyB. If I follow the manual.... Main menu : Navigate | View | AIS | Tools -> Measure Distance, Route & Mark Manager, etc. No option for NMEA 0183 Generator on my OpenPlotter setup.

That sounds like opencpn, it's actually Openplotter you want -
Then for it to work the data you want to make into a NMEA sentence needs to be in signalk - you whats in available as signalk by clicking the signalk diagnostic icon on the top toolbar next to the anchor.

Thanks so much! The only thing in my viewport with open plotter was the menu bar at the top. With tools option of the menu bar not showing the NMEA generator. I am good to go now. Again, thank you!
