New Watchman Plugin

Yes, several files could be used.. but it is more work to implement. Would be useful maybe to use completely different sounds so a more urgent one might sound different.

Any ideas for additional alarms that could be added? I would like to add wind speed, depth sounder, and bilge water alarm but I lack hardware which would provide these inputs.

Code:

public:
watchman_pi(void *ppimgr);

Gah.. how did you even come up with that?

These clips should show the process.

Hakan, Just got back, hope you get this. Been preoccupied & battling with engine, looks like we need a new one, or become engineless like boat_alexandra!

It's been compiled with latest Git fetch origin/master, plus git pull origin master. Took several tries as I got errors initially.

You may need to opencpn.exe with this compile. If so, let me know please.

( I just tried the new compile with my current compile of opencpn.exe and it fails and brings down Opencpn. I have to turn off Watchman in the ini file to fix this. Also under MSVC++ in debug mode, I find immediate errors and breaks. Have to mess with this more. Tomorrow.)

Chuck,
Thanks for taking the time to find this and explaining it. I switched the order now in git.

According to c++ there is no difference at all besides internal data storage which doesn't matter to the program. I can see how this could decrease performance, sure, but causing incorrect code to be generated.. this is a compiler bug not mine.

It's sad they understand the issue enough to write a description, yet don't fix their compiler.

Anyone tried mingw?

I don't know if the attached text file of an email 5-24 to Pavel and Sean will help. Sean may have missed it while he was away, but Watchman.dll used to run in Debug MSVC mode but does not now....some confilicts with error checking I think, even with Chuck's suggestion to switch in post #47

[rgleason]

After git fetch and pull, MSVC shows Opencpn 3.3.604, I will try git clone watchman again, but I believe it causes crash when enabled in ini.

[seandepagnier]

does it still crash? Maybe multiple inheritance is a bad idea if visual studio is compiling.

[rgleason]

I'll git clone in case there has been some update to the plugin. Then let you know.

[Taarnskov]

The last DLL in post #48 make O crash.

The watchman plugin starts a timer to check alarm conditions before the plugin manager sends in the last position fix. So the checks are done with m_lastfix.lat and m_lastfix.lon equal to NAN.

Chuck

[seandepagnier]

Right.. I fixed this but I don't have internet many days so I could not update. For some reason the invalid fix lat and lon are nan, but cog is something different.

[rgleason]

Do you want me to try git clone & compile again?

[rgleason]

Ok did git fetch pull and git clone of this plugin in Lunux Ubuntu
Watchman_pi git clone git://github.com/seandepagnier/watchman_pi.git
Then compiled it, and tested it using Rasch.nmea file and VDR plugin. Tried to get screen capture of boats almost coliding. I was just a bit late a couple of times....

At first I was wondering what this plugin would actually do, now I am convinced that it has some realy good possibillities.

Like the Course error alarm, Landfall alarm and Ais and Gps off alarms. The last frame show Landfall alarrm in red, but the sound did not operate in this case.

-These suggestions below are "future" possibilities....

1. It would be nice to be able to TEST the alerts and alarms to see if they work or are connected coreectly (hardware-software thing).
2. Someone (not Sean) could add a second louder alarm and user defined wait period duplicating a couple of lines of existing code. The two alarms would just sound at the same time.
3. I have hopes this will run in Windows. Hakan had some success previously, perhaps he can test more in real world situation. It has geat possibilities.
4. It has no GPS and no AIS alarms. Doe it have an AIS Boat Collision alarm?
5. How about MARPA Boat collision alarrm? -This is too sophisticated right now, but perhaps later. -How many have Marrpa?
6. Maybe a DSC and MOB alarm upon an MOB DSC signal?
7. What else?

Sean, at first I had trouble picturing what this would actually do. Now I get it. Thanks.

Linux Watchman screen shots showing a Test Alarm and recent improvements by Sean.

Note the current Wiindows version does not have as much info in the first screen for some reason. (See below)

[rgleason]

Windows7 Watchman

Missing some information lines in the first Display about warnings etc. Has the Testing Alarm, and it works Thank you Sean.

lso I can confirm the the sound is set to 4bells.wav for alarms and the timed alarn works in windows and linux I believe.

What would the type of commands that we enter be? Like Dos commands?

Thank you Sean.
