Re: OpenCPN Radar Overlay PlugIn

Chuck...
Should be working.

Check the log.
Are you in OpenGL mode? Should be....
Does the toolbar icon pilot light flash from red to amber to green, or any other combination of colors?

Do you have access to wireshark, the ethernet protocol sniffer? Its a good tool for detecting activity on a network port.

Standing by...
Dave

Dave

OpenGL is on.
The toolbar icon dot stays red.
ipcong shows a connection, but only for 1 minute before the scanner turns off.
I have run with the firewall on and off.
The log has this entry: 22:51:34: ->gradar_pi: Successfully added to multicast group 239.254.2.0

I will download wireshark.

Re: OpenCPN Radar Overlay PlugIn

Chuck....

Great job! I am happy to see that the radar pix I generate are not fabrications of some evil troll in my ram sticks.

Any hints/tricks necessary to get it running on Vista, especially that could bear inclusion in the user manual?

Like you, I am anxious to get underway and look at some real live interesting targets.

Thanks
Dave

Re: OpenCPN Radar Overlay PlugIn

Chuck,

nice to see that it starts to work. A question: do you have perhaps a Garmin plotter at hand to compare the two outputs?

No Garmin plotter here. I am committed to Gradar.

Re: OpenCPN Radar Overlay PlugIn

Radar dudes....

New version of gradar_pi attached.
No real change in graphics or features for this version. I added a debug/diagnostics window which will aid in installation and configuration of the hardware/software interface.

Soon now this code will go under version control, and we can begin real testing/reporting/tracking of bugs and installation details.

Enjoy!
Dave

Re: OpenCPN Radar Overlay PlugIn

Did get it to work, but had to disable wifi for radar's data to be received by plugin from Ethernet port. Dave indicated that he is aware of this issue is if working to fix it. Posted here in case others experience similar issue.

Re: OpenCPN Radar Overlay PlugIn

Hello Radar Junkies!

The OpenCPN Garmin Radar PlugIn is now under source control at an alpha-test state.

The source may be obtained at:
https://github.com/bdbcat/gradar_pi

What's next:

1. Some lingering problems with network configuration on Windows machines. This is WIP.

2. Add controls for Gain and manual Range setting.

3. Improve graphics display. This is basically more eye-candy, after all. Thinking about a 3-D display mode....

4. And of course, test, test, test. I need to get off this dock and go look at some new images.

Enjoy
Dave

Re: OpenCPN Radar Overlay PlugIn

Hi all;

I would like to know if there would be any interest in a Simrad/Lowrance BR24 plugin. They have overpriced interface licenses, which has kept the paid software options either undeveloped or out of reach - over $1k to the developer per seat if I remember correctly.

I am not asking as a developer, but as an interested user. We have a Simrad chartplotter, and I just bought a very lightly used BR24 scanner to be installed sometime soon.

Chris

Wow, I sure know how to kill a thread. Nobody else is interested?

Re: OpenCPN Radar Overlay PlugIn

Witzgall,

The development of open software is based on volunteer financing. Either someone devote their expertise and time, or someone pay for someone to do so.
As I understand it in the case regarding the Garmin plug in, by pure chance, Dave got hold of a radar on a friends boat and made the initial effort to write software to replace the Garmin control console.

A volunteer effort financed Dave to get a Garmin unit to be able to write the "Garmin Radar Plugin"

It could just as well have been the Simrad BR24. But it was not.

So, either we have to accept that for now, the Garmin radar plugin is the first to be developed, get our hands dirty and write it ourself, pay someone to write it or hope that Dave writes the code in such a way that it is easily adopted for use with a BR24.

I am sure the interest for a BR24 radar plugin is as large as for a Garmin.

There is some work done already regarding the BR24 communications protocol, and that protocol is published already.

Re: OpenCPN Radar Overlay PlugIn

Thanks for the explanation. I would be willing to contribute $$$ to help fund an effort, if others feel the same. It is good to know that there is already some headway made to dissect the protocol.

G'day all,
I have no experience using radar so bear with my ignorance.
I realize a "bit" of what you guys do, is not for necessity, but rather just the challenge of doing it. But if you already have a MFD that can overlay, why do you want to do it on OpenCPN. Redundancy?
Or radar at the secondary sheltered helm?
