Re: Feature Requests

manitu..
Yes you can. As long you feed OCPN with the information you can forward it to the AP. See the attached screen shoot of my set up where I use it as of your expectations. I'm sure you'll recognise the language of the commands? :-)
--Or did I misunderstand you??

Re: Feature Requests

(So OCPN will create the VWR sentence wich I need? Thats great!
Installing the new version tonight!!
I guess this routing/filtering ability allso enables me to connect the ap to both nmea0183 through the computer, and nmea2000 through my newly aquired ST70 without risking loop issues? (my geonav plotter is connected to both)

The language is no problem.. people back home laughs at me when I involuntarily goes "hej då"
Never understood the "smørgås" expression though?
(smørgås=butter-goose, a swedish expression for a sandwich.. go figure)

Re: Feature Requests

Well,-create-, that's may be my possible misunderstanding? OCPN will be able to forward the VWR sentence if contained in an incoming stream from a connected instrument. But I don't think it can be converted from other sentences possible holding the same information.
There is another thread in this forum discussing NMEA2000, sometimes called "N2K", please have a look. But nevertheless I do recomend installation of the fabulous OCPN. The best program for navigation I've ever seen.

Re: Feature Requests

Seatalk1 interfacing! I know this is somewhat possible via St1-NMEA bridging , but they all got a limited number of sentences the understand.

But this one..gadgetPool.de
It can recieve and transmit ALL St1 sentences, just wrapping them in a special $STALK NMEA0183 sentence. How hard could it be to make a plugin who makes the seatalk data available to OCPN? This guy has a good write-up on St1 , including a full sentence explanation. Thomas Knauf ****SeaTalk Technical Reference

Something really cool , would be a Raymarine autopilot interface..

Re: Feature Requests

I've been running my Raymarine AP with OCPN for the past 3 years. Also use the dashboard plugin to display my sailing instruments and other data. Raymarine makes a relatively inexpensive ST to NMEA converter box that has a NMEA0183 output to an RS232 cable. I run this to my PC's serial port, or a Serial to USB converter if my PC doesn't have a serial port. Set the ports up in the connections page of the toolbox in OCPN and your up and running. We've used this for up to one week passages with no problems offshore, and following more than 100 waypoints on an ICW route.

Re: Feature Requests

Yeah, Iknow..I'm a bit uncertain regarding my own system, if I'll get problems with HDG/HDM and MWV /VWR differences , wich I believe would be a non-issue with native seatalk.

Anyway , this unit fix my concerns about dual heading and wind sources, and can be freely modified , as its software is open-source. It is quite cheap to at 120 euros, and available in europe.

Expanding the firmware of this converter might be a better project , but as I'm not a programmer , my only contributions would be testing and donations for hardware for the programmers.

edit: I was thinking of a full AP interface, as without Ray's Control head.
Does anybody have the Raymarine converter's accepted centences list? Or Know wich converter understands the most sentences?

Re: Feature Requests

Manitu,
I'm not sure of this, but there might be a problem to your plans. I don't know how much of the programming and calibration is stored in the control head, if any. If so, it would be exceedingly difficult to clone the control head in software, I'm guessing. I'm not a programmer either.

It's important to point out that large parts of the seatalk 1 protocol have never been decoded. , what's available is typically the common NMEA 0183 sentences and there equivalent ST1 sentence. This is the bones of Thomas Knauf decoding works that allows such encoders to be built in the first place

It's the product above, all other seatalk data is transferred as $STALK , a custom NMEA header , BUT , the data will be gibberish as you'll have to decode it yourself with no supporting documentation.

Hence to build say an autopilot interface would require reverse engineering all the proprietary st1 sentences associated with the control head to AP comms, something I don't beleive anyone's tried. Not only would the data formats have to be decoded, but the usage of such data and the sequencing of such data understood as well

It can be done , and Raymarine has done it in the new MFDs !

Re: Feature Requests

Post #1539 Update PC Clock with GPS Clock.

Post #1541 Information regarding GPS, UTC and Atomic TAI time -Viking

Post #1542 Free Solutions - Pavel
Quote:
If there weren't ready made free solution that can happily coexist with OpenCPN and do it, maybe. But I don't see any real reason why not use GPS clock freeware or gpstime - Script that sets system time through a GPS. - Google Project Hosting depending on the platform...
Post #1543 We have it but too little time - Bdcat

=====

I think this feature would be useful for several reasons.
1. Celestial Navigation Plugin - help with setting PC time.
2. Weatherfax Plugin - several weather fax programs use GPS time for timing the satellites.
4. Pavel has listed several free solutions, but it would be simpler if this could be done at some point....

Is it worth putting into Tracker -Feature requests? ..somewhere just above Low priority?

Re: Feature Requests

Hello,

I don't know if somebody already asked for that, but it would be nice to have to windows opened side-by-side on the screen with two different scales.
And, of course, to be able to play separately in each screen...

Re: Feature Requests

Jean,

You might try to have a look at the Portable OpenCPN as described in the User's Manual (section about Installing OpenCPN).

It will give you two completely independent windows, as requested. I often use the other one for planning tasks when underway.

Re: Feature Requests

The portable solution does the trick today.
Nethertheless allowing for several viewports would come handy.

Added to feature requests:

FS#1292 - UI- Allow for several parallel viewports

Re: Feature Requests

Yes, but I use a MacBook with OSX.
I've tried the portable solution on Windows in a virtual machine. It works OK but I don't want to use Windows.

Re: Feature Requests

Hi.
Ref. to Flyspray FS£1161 FS#1161 : AIS Add country to the target query dialog
I've made my code trials to get a the country code in the AIS query- and roll over- dialogue boxes. The patch is in Flyspray as a Git Diff.
The results are a short country code in the roll over box and the full country designation in the query box. Please see my screen shots.
Hopefully someone else also find that this is a good idea and give it support?

Thanks Håkan
