I suppose your right... perhaps too much coffee today... twitching is the name of the (video) game. BTW, only using 2-5% processor load @ 250ms.

Ok, for "look ahead for course up mode". Basically we would be looking further ahead up the chart in course up mode, so we would see 15% more chart in front of us than behind.

Function works like this:

1. Get chart window vertical size
2. Get pixel along cog predictor line 15% of window vertical size
3. Center chart on pixel rather than boat position

I'm working on moving from python to cpp so I can help with this stuff... I promise.

build for windows

Hi guys,
I've made the build 529a available at http://www.xtr.cz/opencpn.zip - just download, unzip and run the exe...
It contains also SourceForge.net: OpenCPN: Detail: 3001576 - Go To Position Dialog but the impact on stuff Dave changed should be none...

Happy testing

Pavel

You can of course build a Release opencpn.exe with VS, and then simply drop the new .exe in Program Files/opencpn, or wherever.... It will use the existing data files.

Dave
Dave, Jan, Blu,

A copy of the release compile of 529a is available at:

http://dl.dropbox.com/u/2091730/opencpn.exe

Just copy it on top of your existing opencpn.exe file.

Paul

Will....

Forget to mention: You can change the Course-Up refresh period from the config file. 15 secs is default.

[Settings]
COGUPAvgSeconds=15

Have fun!
Dave

Dave,

I know that this has been proposed before, but considering the processor load presented by the course-up implementation, perhaps a reconsideration of a manual chart-up mode is in order. Just a couple of buttons to rotate the chart clock-wise or counter-clock-wise. This would reduce the computation rate down to human time.

Paul

ok, ubuntu 10.04 cvs 529a works a treat.
i did this from aforementioned tips (thanks)
apt-get install libgps-dev
ln -s /usr/lib/libgps.so.19.0.0 /usr/lib/libgps.s
and the usual cvs download & make routine

the first thing i noticed was my desktop shortcut didnt work, it was pointing to /usr/local/bin changed it to /usr/bin
select Network LIBGPS /localhost
and the gps functionality works well! i dont get the signal strength bars that i noticed were depicted in a screen shot, just a pointer & a green dot indicating the connection.

if someone else has said all this above, my apologies, i'll RTFM l8r
cheers & thanks again

529 not working

can't get 529 EXE downloaded from either of th above sites to work. XP SP3. unzip. only find an exe that's the ap, not an installer. drag the exe into the progrm folder for ocn. then get an error about the ap not being cofigured correctly... reinstall ap. i'm copying it over 527a which worked fine.

ideas?

Thank you Will,
I get it. :-)

jpirbrig,
You still have to download the latest source code via:

cvs -dserver:anonymous@opencpn.cvs.sourceforge.net:/cvsroot/opencpn login
cvs -z3 -dserver:anonymous@opencpn.cvs.sourceforge.net:/cvsroot/opencpn co -P opencpn


Then change directory (cd) to opencpn and run the commands that Will posted, i.e.,

cmake .
make
sudo make install

529a is just to good to be true......
Now I don't even need to have a gps, opencpn takes care of that.

When disconnecting the gps 529a continued for several minutes to show variable speed and course, before settling.Now, 10 min after pulling the plug on the gps, I still have a COG & SOG & green indicator!!

There seems to be some problems with "Network LIBGPS".

Blue,

At the moment I am unable to download 527a from the OpenCPN site. So, I am unable to recreate your problem. However, I have had problems in the past with release versions vs debug versions. Here is a link to a zip'd version of 529a debug that you can try. Just unzip and replace the 527a version with this version.

529a dl

thanks for posting that Paul. downloaded and unzipped fine, but same prob - application isn't configured correctly.

when i copied over just the exe on 526 it worked fine.

is there a config file i need to delete or something?

Blue,

Lets make sure we are on the same wavelength. Assuming that you have a working 526 version -- you should be able to open in explorer the folder C:\Program Files\OpenCPN and replace just the opencpn.exe file found their with one of the two opencpn.exe 529a files you download. No other files need to be touched or changed. Also, with the OpenCPN fold still open, the program should run when you double click on the .exe file.

Regarding my post #625.
I can also see a problem with gpsd, that does not respond correctly to an unplugged gps BU 353. SOG & COG are zero but, position inf stays at latest value and satellites continue to show in xgps. Killing xgps resulted in a continuing big gpsd process activity, when it was not expected(by me).
