OpenPlotter project

Hi Sailoog & rgleason,

I have made a pull request to opencpn for my changes to the dashboard_pi.cpp, dial.cpp and instrument.cpp.

thanks

[rgleason]

Nick_c thankyou for the dashboard contribution. Hope you troubles are resolved.

Hi Sailoog,

Would it be possible to incorporate this NAVTEX code in to your work, here's the link from youtube. Low-Cost NAVTEX Receiver https://youtu.be/SwL_ZQ_iBIM

He's released the code, http://fmode.de/NavTex_Receiver_by_kutt.txt

So hopefully asking permission to use the code for your work should be ok. The hardware needs to be built, I've asked if he could write a simple tutorial for the building of the NAVTEX Receiver.

It would be nice if there's a NAVTEX window, that could be drag and resized, displaying NAVTEX messages.

Thanks

Could someone recommend a Pi3 / openplotter compatible wireless keyboard and mouse please? Should I go Bluetooth or WiFi?

Thanks

You can make a Navtex-receiver even cheaper with just a SDR, and let the software do the decoding.

95% of the time after the system is installed and operational, you will only use the mouse. I have seen hundred's of fishing boats using the Logitech cordless marble trackball, and the reason is simple: you do not have to move the mouse when operating, you only scroll the ball on the mouse. Very convenient with limited space on-board a vessel. Except for that recommendation, I would try to find a keyboard that has native F1 to F12 function keys that can be handy to use with opencpn. Nowadays, it has been more and more usual to use the F1 to F12 keys for multimedia functions and you will have to press shift to get access to the F1 to F12 functions, not so convenient when it's a little choppy waves and you try to operate your navigation pc.

Is there a cheap sdr which will receive down to 518Khz? Would be great if there is, then wfax would be with reach as well.

I've been looking can't find one that covers that frequency of 518Khz

[Alekoy]

Yeah, It turns out that the video I found and based my response on used a $300 SDR.. so not cheap at all...
theoretically if you had a radio that you could tune to the correct frequenzy and fed the audio into a computer, it could decode the data, but that way, the arduino solution mentioned earlier would be better

It appears that your best bet is to use an up converter.

Degen 1103's are excellent ssb receivers, not that pricey. Then fldigi running on the Pi will decode. Though I use the ham radio I have onboard. Downside is you need to remember to turn in on and run fldigi to receive, an upside is you can cut and paste lat and long of nav warnings etc from the messages straight into opencpn waypoints.

Hi Guys,

I have been thinking about the CAN interface, could it work with a wifi version of a obdii device?
To save having to run more cables through the boat.

My idea goes like this,

Connecting the obdii device (elm327 wifi) to the N2k (can bus) only using the can high/low pins and power pins.
Inputting/outputting the wifi signal into openplotter.

I can't anything about it being bi-directional.


Link to cheap device,
https://www.amazon.co.uk/s/?ie=UTF8&...l_8w12qtniqs_b

Any ideas for or am I missing something?

Ps. I have fixed my rpi, problem with .Xauthority, deleted and recreated resolved the issue.

Thanks

The ELM327 does not support N2k.

Hi Alekoy,

Maybe I am getting my terminlogy wrong, from the Raymarine manual for my C-series plotter, it implies than you can connect any N2K device straight to my SeatalkNG network as a spur device. Which is the way I was/am going to connect the can-usb adapter which Openplotter is referring to.

I guess my underlying question is, is there a difference between the can-usb adapter and the ELM327 on the "can" side and can openplotter handle the output of it? Also is the ELM327-wifi a bi-directional device?

Thanks
