  Logging data
Posted by: PaddyB - 08-22-2018, 05:11 AM - Forum: How I did it - Replies (2)

Well that was easy!!!

After years of jumping through hoops with node-red saving data to a sqlite databases then creating queries going into node-red charts, last night I had a look at other offerings. Simple! Install influxdb and chronograf then set up the signalk store to influxdb app and that's it! 
I did try influxdb and some other viewing options ages ago but gave up as it was such a resource hog, seems much better behaved these days  Cool

Chronograf has a handy plot delayed data so you can overlay a day ago or whatever to compare. 
(Below is just an hour delay, haven't got a days data yet )

  Reading rudder sense
Posted by: jodi001 - 08-17-2018, 07:57 AM - Forum: General discussion - Replies (5)

Hi,

I have successfully in installed opencpn with NOOBS and got my IMU sensor to deliver data to pypilot. My arduino acts like a controller (connected to USB port) and so far a small RC servo reacts when I move IMU and set AP course, great! 

In my boat I have a hydrualic pump with reversing motor that I would like to control via H bridge. Before I install it and try I need to be sure that I do not stall this pump and create damage, therefore I need to able read rudder angle and current but I cannot figure out how to get the reading i opencpn. I have attached a potentiometer to my arduino at adc5 and give it 5 V and ground.

Thanks for a great work!

Regards,

Joakim


  SignalK navigation.attitude
Posted by: sbender - 08-16-2018, 09:36 PM - Forum: Bug Reports - Replies (1)

navigation.attitude is not getting into Signal K properly. It looks like it sends individual deltas separately for pitch, roll and raw. It should send one delta, where the value is:

{
  "roll" : 0.031,
  "yaw" : 2.1298,
  "pitch" : 0.0281
}


  Moitessier Hat: FABULOSO !
Posted by: Cap.Badone - 08-16-2018, 01:52 PM - Forum: Español - No Replies

Recién acabo de recibir y actualizar mi proyecto con el Hat Moitessier y creo necesario hacer un receso en la parametrización para expresar mi admiración y agradecimiento públicos por el trabajo realizado por tanta gente, algunos de este foro, para llegar hasta aquí.
 
OpenPlotter y OpenCPN instalados “casi” automáticamente sobre la Raspberry Pi3 model B con el Hat Moitessier y todo funcionando bien a la primera:
·         Compás, corredera y barómetro: con los sensores del Hat.
·         GPS: con el sensor del Hat, sin antena exterior.
·         Ploter: con el ya estándar OpenCPN.
·         Cartas: actualizadas, con oeSenc.
·         AIS: solamente con añadir una antena VHF exterior, sin necesidad de calibración.
·         … y otras señales de dispositivos integradas a través de OpenPlotter.
 
Tener todas estas funciones disponibles a muy bajo coste y sin necesidad de grandes conocimientos lo considero un éxito fabuloso de todos  los que habéis participado en los distintos proyectos. A todos vosotros: GRACIAS !


Question Moitessier HAT - HELP! Did not work :(
Posted by: Mateusz C. - 08-16-2018, 07:32 AM - Forum: How do I...? - Replies (1)

Hi everyone!

I am new here. That is why I will introduce myself to the beginning: I am Mateusz, I live in Poland. I heard about the OpenPlotter project some time ago. However, only now I managed to implement it on my own.

I do not have my own sail yacht, so I wanted it to be closed in one housing. To make the device more handy, but with the possibility to be permanently installed on the boat.

The whole is based on Raspberry Pi 3 model B + and Moitessier HAT. The attached drawing shows the general idea of the device.

I have a problem with Moitessier HAT. It looks like it works normally, but when I try to get a GPS position I can not do it. As if OpenCPN did not communicate with Moitessier HAT at all. The LED status light indicating GPS status is always on.

In addition, IMU sensors do not always work. Sometimes, during calibration, they show the movements of the yacht, the compass shows the direction. Otherwise, it looks like it would not send information to OpenPlotter.

I have not checked AIS yet

I installed everything in accordance with the instructions from the documentation contained on the website. I tried to search for something here on the forum but I found nothing.

I reinstalled the entire OpenPlotter software and reinstalled the Moitessier HAT driver. I remembered about updates ...

I also disconnected the entire USB hub to see if this causes interference in Moitessier HAT.

Can anyone tell me what else I can do to force Moitessier HAT to cooperate? Is it possible that my Moitessier HAT was damaged somewhere on the way to mine? Or maybe I'm doing something wrong?

Please help.

Mateusz

  Radio receiver with a fun cube dongle pro plus
Posted by: PaddyB - 08-16-2018, 05:39 AM - Forum: How I did it - Replies (3)

At last! It works, a good few years ago I bought a fun cube dongle pro plus as a little present to the boat, and finally it works on the Pi. 
http://gqrx.dk/download/gqrx-sdr-for-the-raspberry-pi
Download the zip file onto the Pi then in a terminal change directory to where the downloaded file is and run >   tar xvfJ gqrx-sdr-2.11.5-linux-rpi3.tar.xz
Then go into the gqrx directory and run > 
chmod +x gqrx
Then run >  volk_profile
And wait a while, then in the same directory type ./gqrx.
And you should be up and running, with the fft display turned down to 1fps or off audio is largely stutter free. I've a hifiberry amp so can play back over the speakers, listening to the local airport tower this morning. Lots fun :Cool
Also can save to an audio file so you can record weather faxes then open in fldigi to decode into an image. 
Should work with a RTL dongle though haven't tried it yet.

  Problem on Android WiFi with headless RPi 3b+
Posted by: Sailabout - 08-15-2018, 10:01 AM - Forum: Bug Reports - Replies (1)

Hello

I can connect through WiFi and use OpenPlotter on a headless Raspberry Pi 3B+ with Windows 10 on a laptop and on a dual OS tablet (Windows 10 and Android 5.1) without problem but I cannot connect with my Android tablets (the above mentioned dual OS tablet, another with Android 4.04 and one with Android 6.0). When trying to connect through WiFi, I get an "Authentication Problem".
I use the Noobs version of OpenPlotter downloaded on august 14. I am new on OpenPlotter as well as on Raspberry Pi.


  OpenCPN “send to GPS” via OpenPlotter
Posted by: Zeilbootje - 08-14-2018, 06:35 AM - Forum: How do I...? - No Replies

OpenCPN is connected through localhost to OpenPlotter and OpenPlotter has a serial connection to my mux. In OpenCPN when I want to send my route and way points I only can select a comport. Any ideas how I can send the track/way points trough the localhost to the serial connection via my Mux to the Raymarine C80 plotter? 

Do I need to make a virtual com port in OpenPlotter that is connected via the network? Any suggestios on how to tackle this problem?


  Autopilot data
Posted by: affinite - 08-14-2018, 04:29 AM - Forum: How do I...? - Replies (2)

I'm trying to configure 1.1 on the boat and it's driving me nuts!
I can't get my mqtt in and cpu utilisation is hitting 100% causing ocpn to hang. My biggest problem is that I can't seem to get autopilot course info out. I've installed the signal K to nmea plugin and configured it to generate RMB but I simply don't see the RMB sentence anywhere in the system when I see a route arrive in OCPN.
Any pointers gratefully received otherwise it's back to 0.17.1 (which did work) while I regain my sanity
