Is your design special?

No it isn't anything special, never claimed it was. Just thought it would be nice to share the combined hardware you outlined with software modified to output a nmea stream all in one place.

[Taarnskov]

I find it very interesting with all the information we can get ind and out of OpenCPN now, and hopefully in the future.

I believe that it is important to make every plugin focused and easy to comprehend, and i would therefore suggest that we keep curves out of the dashbord plugin, and make a seperate plugin as I surgeste in

Lars, Its a good idea, perhaps you should put it in Flyspray. Have you registered? Its quite easy. Maybe even leave a link to your post. OpenCPN::Tracker All Projects: Tasklist

[Taarnskov]

I am not registered in Flyspray, but I will see if i can do it during the weekend.

Hi,

I try to play with "wind history" and it works perfect on Windows 7,
but if I try to do that on Ubuntu 12.04.2 LTS it doesn't.
I used on both system the same OpenCPN 3.3.604 and the same VDR data.
Have anybody idea what is wrong?

@Pavel: I'm not sure if this Feature is of general interest, but feel free to add this to the beta release as a new feature.

I also added a new setting to the "opncpn.ini". With "CalculateTWfromAW=1" the calculation of TW is switched on. For convenient use, I also updated the Dashboard Preferences/Appearance dialog to control calculation.

Any feedback (suggestions/corrections) is welcome.

For users with strong currents it might be better to use SOG instead of STW. But this is currently not relevant for me.

This is the new code:

// Send calculated TWS (from AWS and STW)
if (g_iDashCalculateTWfromAW==1)
{
if (m_NMEA0183.Mwv.WindAngle < 180)
SendSentenceToAllInstruments( OCPN_DBP_STC_TWA,
90-(180/3.1415*atan((m_NMEA0183.Mwv.WindSpeed*cos(m_NMEA01 83.Mwv.WindAngle*3.1415/180)-m_NMEA0183.Vhw.Knots)/
(m_NMEA0183.Mwv.WindSpeed*sin(m_NMEA0183.Mwv.WindA ngle*3.1415/180)))), _T("Deg") );
else if (m_NMEA0183.Mwv.WindAngle > 180)
SendSentenceToAllInstruments( OCPN_DBP_STC_TWA,
360-(90-(180/3.1415*atan((m_NMEA0183.Mwv.WindSpeed*cos((180-(m_NMEA0183.Mwv.WindAngle-180))*3.1415/180)-m_NMEA0183.Vhw.Knots)/
(m_NMEA0183.Mwv.WindSpeed*sin((180-(m_NMEA0183.Mwv.WindAngle-180))*3.1415/180))))), _T("Deg") );
else
SendSentenceToAllInstruments( OCPN_DBP_STC_TWA,
180, _T("Deg") );

// 4) Wind Speed Units, K/M/N
SendSentenceToAllInstruments( OCPN_DBP_STC_TWS,
sqrt(pow((m_NMEA0183.Mwv.WindSpeed*cos(m_NMEA0183. Mwv.WindAngle*3.1415/180))-m_NMEA0183.Vhw.Knots, 2)+
pow(m_NMEA0183.Mwv.WindSpeed*sin(m_NMEA0183.Mwv.Wi ndAngle*3.1415/180), 2)),m_NMEA0183.Mwv.WindSpeedUnits );

Andreas...

Would you mind rebasing your modifications on the current code from the master? Actually the best would be a pull request on github, but if you for some reason don't want to use it, just send the output of

git diff

Thank you

Pavel

How did you transfer the file between both systems? It may have changed line endings. NMEA expects CR+LF aka \r\n
Apart from that, the file should play just fine.

Please check and report.

Thanks,

Hi,

As you can see on both screenshots (windows & linux) on dashbord with "True Wind Dir & Speed" data from VDR file are good. AIS info on both works without any problem. It looks like we have problem only Wind History dashboard on linux version.

Hi,

while it is not a bad idea to have the ability to extrapolate true wind from apparent, i have the st60 on my boat and true wind/angle/direction/speed is available on the graphic display.
I also have a seatalk>nmea0183 adapter on my boat and to me it seems that seatalk does transmit true wind angle, direction and speed. By looking at the NMEA debug window in the options I see two MWV sentences, one with included "T" and one with "R".. which i would infer to be true and relative.
i am at the dock so cannot categorically confirm this at present (as both sentences have same data), but the structure seems to be there.

regards, Ian

OK, sorry, I misunderstood your problem. Sorry for that. Can you send me your VDR sample file so I can test and fix the problem.

Thanks,

Hi Pavel,

If I find the time to get familar with git, I will do the changes for TWS calculation in the latest code.

Regards,

Andreas

[Homberger]

Hi Ian,

It did not work for me, but perhaps it's filtered from the SeaTalk bridge. I will check next Weekend.

If true wind informnation is available then the additional calculation is not necessary.


Regards,

Andreas

Hi,

I attached VDR file. I got it from File Thingie 2.5.7.

[Taarnskov]

The true wind information, relative to North, is not present when using nmea information coming from the st60. I have the nmea information true and relative wind relative to the boat from the ST60, and the magnetic heading from a solid-state compas. It would be nice to have those information combined.

Lars

[Taarnskov]

I have found that i get no wind-speed information on the dashboard if my st60 is set to m/s, but if i set the st60 to the unit knot i get the information in the dashboard display. Can I do anything to change that.
