Roy,

I think you've found the wrong openPilot list! We are working on marine
chart plotting. I think you want the guys at http://forums.openpilot.org/

[Openpilot-developers] Question about availability of CC

[Roy S. K. <ro...@ka...>]

Hi all

Anyone that knows when new CCs will be available? i'm rather eager to get started building a quadcopter, but without the CC, I'll be stuck with a KK, which isn't really what I want.

Vennlige hilsener / Best regards

[Openpilot-developers] Ability to control speed controllers and RC servos added!

[Tim B. <ti...@en...>]

Ladies and Gentlemen,

I realise that this mailing list has been quiet for the last few months, and 
this is largely because I have been concentrating on getting my house in 
order. It is getting there slowly. The good news is that I have added a little 
to OP over the last few months.

New code has been committed to CVS in the "Servo" directory. It provides 
capability to control one of these:

http://www.pololu.com/catalog/product/1352/resources

The USB control is done directly through libusb-1.0 and the commands sent to 
it have been deciphered from the POLOLU source. It is not fully featured, but 
it does allow you to set position. This might be useful for anyone who intends 
to use it for hobby or autopilot purposes.

I have an upcoming project to monitor and record various details of a racing 
dinghy, which will require improving the ADC support to handle MAX-11210 ADCs 
for load cells, as well as magnetometers, and possibly accelerometers. And of 
course, wind instruments and GPS. Don't hold your breath on this, but it is 
coming. I will photograph all of this and put together a presentation as it 
progresses.

Cheers all,

Tim B.

[Openpilot-developers] Map widget plotting is fixed!

[Tim B. <ti...@en...>]

Ladies and gentlemen,

Some of you will remember that when I re-wrote the map widget plotting
routines to run in parallel it broke the plotting system, spewing
artefacts all over the widget. I am pleased to say that this has now been
fixed and committed to CVS. I have also brought the option to use
multi-threading under software control, instead of a compile-time option.

I am currently working on a small utility to extract sections of coastline
in a given area. This will allow you to load and use only your local
coastline as opposed to that for the entire planet. This should reduce the
memory footprint a bit, and will not hurt speed either. Hopefully this
will be on CVS before christmas, and it later it will be integrated into
the main OpenPilot GUI.

Cheers for now,

Tim B.

[Openpilot-developers] Website updates

[Tim B. <ti...@en...>]

Ladies and gentlemen,

We have a WIKI!!! Feel free to visit, register, and start sharing your 
knowledge and experience of OpenPilot.

I have also built a status panel widget. It uses geometry in *.3dm files, which 
are native to the Rhinoceros CAD system, but there are some open-source 
packages which will export them.

The status panel requires a multiplexed data input, so I've written a widget 
called "mux" to do the conversion (from, say data(double) to data(int, double)  
ie. adding a channel number). The status panel expects a file called 
"settings.xml" in your ~/.openpilot directory, which will become the standard 
settings file for everything.

I have also improved the install script. Please see the FAQ on the wiki for 
details on how to use this, but it is now a bit more complete.

Cheers for now,

Tim B.

Jan,

OpenPilot hasn't recently been compiled on Windows. In the last few months, 
the map widget has been re-written extensively, so I make no guarantees! I did 
manage to compile the map widget under Windows using MinGW way back in 2009 
(2nd Quarter? who knows!). Most of the other code should be possible to port 
reasonably easily, if it doesn't just compile straight away (one of the 
advantages of using QT).

At present the map widget doesn't contain much for route planning (I just 
haven't got there yet!) and it is still in a bit of a state of flux as I finish 
the layout of the chart plotting system. This is moving towards renderers, 
datastores and data loaders, which is how the CM93/2 and point of interest 
handling is written. Hopefully this will make the dependencies more modular 
(eg. enable the user to remove the GDAL dependency without crippling all chart 
support as at present).

My thoughts so far on route planning were to use the map widget to provide 
locations (perhaps by mouse-click, or nearest object) to a separate widget 
which could then supply data to an autopilot or similar. This hopefully 
prevents the map widget from becoming too large (it's already pretty big), and 
hopefully allows us to re-use the lighter route planning/route control widget 
on lower-spec hardware than required for the full map widget.

At present I'm developing on Debian Squeeze under KDE4.2 with standard tools. 
If you'd like the job of porting the code then it's yours! I would suggest 
that you start porting the simpler widgets first, then work up to the widgets 
which have dependencies (notably AISDecoder--sqlite3 and the map widget - 
GDAL). I would not be surprised if you have trouble with GDAL, but you can use 
older versions if you don't want/need GRIB support.

Thanks for your interest,

Tim B.

[Openpilot-developers] USA software freedom infringement

[Tim B. <ti...@en...>]

As some of you may know, Sourceforge recently blocked users in some countries 
from downloading content from Sourceforge.net. Interestingly, I can't find any 
e-mails from Sourceforge informing me that this blocking was going to happen. 
The full story is linked below.

http://sourceforge.net/blog/clarifying-sourceforgenets-denial-of-site-access-
for-certain-persons-in-accordance-with-us-law/

I take the freedom of software very seriously, and I see no reason why we 
should pander to the US's idiocracy. OpenPilot does not constitute a Military 
or Strategic capability, and it is therefore perfectly reasonable that it 
should be available worldwide. 

For the moment, the CVS repository will remain on Sourceforge, but if there is 
any further restrictive action, I will move it to my own server and host the 
content myself. I have no intention to stop developing, or change the license 
we operate under, but I feel very strongly that if we are to develop free 
software, it is for the benefit of everyone, not just our best friends.

You will notice that the web address in my signature has changed. I have been 
hosting the site for some time now, with no issues at all. You may use the 
direct URL (below) or access the site via sourceforge, whichever is more 
convenient.

[Openpilot-developers] Monthly News. Feb 2010

[Tim B. <ti...@en...>]

Ladies and Gentlemen,

There have been quite a few changes to the OpenPilot source recently. None of 
them have been comitted yet, because they're still not particularly stable. 
There have been some minor improvements in the NMEA Parser and AIS Widgets 
(like loading xml AIS data in a separate thread), but the main work has been 
going on in the map widget.

The normal screen plotting now uses a multi-thread mechanism, where each layer 
of data is rendered to a QImage, then each QImage is composited to form the 
display which we know and love (well some of us love it). While I have been 
doing this, I have also added alpha-channel blending to the AIS plots, which 
means that the older position fixes are semi-transparent. This looks quite 
neat, and an example is in the screenshot below.

http://openpilot.engineering.selfip.org/gallery.php?display=Screenshots%2FScreenshot0022.png

There is a possibility that we will have a new developer, who wants to develop 
an autopilot system, and feels that OpenPilot would be a suitable base for 
this purpose. I find this very exciting, as it's the exact reason for OP being 
written as it is. Of course, the extra active developer is nice as well!

Finally, this news e-mail is new. I'll try to do it every month to let 
everyone know what's going on with the code. I realise so far I have missed 
release dates like they haven't even been there, but I'm hoping that the first 
official version will be something worth waiting for.

Cheers for now,

Tim B.

[Openpilot-developers] NMEA 2000 Support - Offer for collaboration

[Tim B. <ti...@en...>]

I recieved this e-mail from Andrew today. He seems quite happy to share 
knowledge of NMEA2000. Would anyone like to develop this in a similar way to 
the existing NMEA0183?

Cheers All,

Tim B.

----------  Forwarded Message  ----------

Subject: Our C# project
Date: Thursday 14 January 2010
From: Andrew Mason <a....@au...>
To: tbr...@us...

Dear Tim,

I have just come across your Open Pilot project (via your comment at
http://www.boatdesign.net/forums/onboard-electronics-controls/avia-virtual-
instruments-windows-pcs-27994.html), 

and wanted to tell you about the work that we are doing in the
University of Auckland, New Zealand. I supervised a student project last
year to understand the NMEA 2000 (N2k) format. As part of this, I have
been liaising with Kees (http://yachtelectronics.blogspot.com/) to share
what we have learnt; you may have seen his occasional comments on
Panbo.com. He has created an XML file containing N2k definitions for us
to use.

I have also been working with a student on developing open source
software in C# to receive and display N2k data. We are currently adding
the ability to handle 0183 messages as well. The user can build their
own displays using the C# compile time editor, which (with thanks to
some C# tricks) gives us access to lots of standard C# dial and text
controls. This code is not yet released anywhere, but will be
soon(ish!); I will let you know when this happens.

Our software does not have any of the plotting capabilities you have
developed, but otherwise has similar goals.

If you are interested in adding N2k support, then it may be beneficial
to work together on this. Our code attempts to be very general in that
it read in an XML N2k definition file from which the N2k support is
constructed. (Our XML file is somewhat more detailed than Kees' file.) A
similar approach would work in C++. Collaborating on standard schemes
for sending N2k over ethernet could also be good. We currently use the
Actisense NGT N2k-to-USB adapter for our interfacing; if you are
interested, I can give you details on how to use this without requiring
any Actisense DLL's.

I look forward to hearing from you. Cheers,

Andrew

PS: You can see some early N2k-related images at

Andre,

Thanks for your interest in the OpenPilot project! It's nice to know that it's 
getting noticed.

To be honest, I'm not particularly interested in the commercial aspects of 
this project at the moment, for a few reasons, but mainly beacuse I don't have 
the time (or the developers) to develop a commercial piece of software (well, 
not in addition to a full-time job).

However, there are areas which lend themselves to commercial involvment, 
particularly with miniature tank displays and data repeaters, and with larger 
multi-monitor bridge systems. The former is under some investigation, and will 
feed into the latter.

Hardware at the moment is starting to look like a bespoke solution on a per-
yacht basis (although in it's simplest form it is a PC in a waterproof case).

In the first instance, I suggest that you consider installation in your own 
yacht. I will be approaching some of the large pleasure boat manufacturers at 
the end of next year to gauge thier interest in a flexible bridge system.

If you have any queries please don't hesitate to contact me.

[Openpilot-developers] Support for CM-93/3 charts unlikely

[Tim B. <ti...@en...>]

Ladies and gentlemen,

Due to the e-mail below, I can't afford to develop support for CMap's CM93-3 
format for UK waters, and I suggest that we focus our attention on other 
vector chart formats.

The obvious suggestion is the Admiralty Vector Chart Service which uses the 
IHO-S63 data format and starts at about £140 for a folio of 10 charts, then 
£15 per chart thereafter if my memory serves me correctly.

Thanks,

Tim B.

[Openpilot-developers] OpenPilot Website details

[Tim B. <ti...@en...>]

Ladies and Gents,

The web site is going through (yet) another facelift, but I'm pretty happy 
with the result so far, and it makes for easier branding than the 2009 
version.

Could anyone who wants their details on the site drop me a note with thier 
details (and perhaps a bit of blurb).

I can now get business cards from VistaPrint for OpenPilot. Please let me know 
if anyone is interested.

Thanks,

[Openpilot-developers] CM93-3 charts of the Solent for OpenPilot

[Tim B. <ti...@en...>]

Dear Sir or Madam,

I have recently contacted your southampton office to ask for some assistance in 
implementing support for C-Map's CM93-3 vector chart format within OpenPilot.

OpenPilot is an open-source (freely downloadable) software project to provide 
sailors with a customisable navigation and monitoring mechanism. The full 
source-code is available on the web, and anyone with an interest is welcome to 
contribute. Support is already provided for S-57 charts, which cover North 
America, but I do not as yet have any coverage for the rest of the world.

I have found another Open-Source project (called OpenCPN) which claims to 
support CM93-3. Since the source-code for this is available, it is my 
intention to base Open-Pilot's CM93-3 implementation on the read-routines 
present in OpenCPN. I have no intention of using this system to bypass the 
security and encrytion of the CM93-3 charts, though I am aware that the system 
is open to abuse.

Therefore, I would very much appreciate any assistance you could provide to 
see if OpenCPN will import a CM93-3 format chart, and if so, purchase charts 
for the Solent (similar area to SC5600 folio), which should allow me to begin 
implementation of at least the UK charts.

I would also appreciate it if you could tell me the typical cost of the CM93-3 
charts.

Many thanks in advance,

Tim Brocklehurst.

Re: [Openpilot-developers] OpenPilot tank sender support

[Tim B. <ti...@en...>]

Martin, 

I'm really interested in making sure that what I think is going on is actually 
the case, primarily so that I can document the required circuits and code. 
This will allow us to provide a tank display in future, which will become 
ever-more useful as OP becomes a mechanism for integrated bridge systems.

All I am asking from you is really to borrow some hardware for a few days to 
build up the interface electronics.

Thanks,

Tim Brocklehurst

Re: [Openpilot-developers] Collaboration between Hybrid-Marine Ltd and OpenPilot

[Tim B. <ti...@en...>]

Graeme,

Thanks for your quick response. I appreciate that you would not wish to 
compromise your signalling protocols (I had assumed that you were using 
standards-compliant signalling).

I am well aware of the current economic situation, and I appreciate that few 
companies have excess resources. Ironically, this is a very good thing for the 
uptake of Open-Source software, but it is not good for its development when 
collaboration is required!

Please don't hesitate to contact me if you wish to use OpenPilot, or 
collaborate in its development in the future.

Thanks,

Tim Brocklehurst.

[Openpilot-developers] V1 beta has been released

[Timothy B. <ti...@en...>]

Ladies and Gentlemen,

I am pleased to announce that OpenPilot v1 beta has been released. I hope to 
release the final V1 in January.

As you are all aware, OpenPilot is primarily written for Linux, but can be run 
on windows if the charts and grib data are disabled.

Cheers,

Tim B.

[Openpilot-developers] (no subject)

[Tim B. <ti...@en...>]

Ladies and Gentlemen,

I thought it was about time I sent another quick e-mail to the list. As
some of you may know, I have been quite ill recently, which has affected
OpenPilot's development somewhat. However, I am now recovering, and you'd
be amazed how few things there are to do at home when you can't do
anything manual. Hence some of you may have noticed a flurry of commits to
CVS in the last week or so.

I think we're now at a point where most of the code is quite stable. There
are bugs in it (the AIS calculations for instance, and OSM only reporting
streetnames for the first loaded patch). I have added a point of interest
system, so that you can import chart geometry from an XML file. This needs
a small tweak, to allow us to handle all forms of geometry, at present it
only does buoys. I'll do this over the next few days.

I have re-built the Website, and it is now being hosted on my server.
there is an automatic 301 redirect from http://openpilot.sourceforge.net
so there is no change in the operation of the site. We also now have a
logo, that will make it into CVS when I get round to it. If anyone has
screenshots or pictures of OP in action (anyone got it near a boat yet?),
just e-mail them to me and I'll get them into the gallery.

A point now for our UK developers. I have spoken to Kelvin Hughes (chart
suppliers in Southampton) and it seems that all the admiralty Vector
Charts are supplied in S-63 format. S-63 it turns out is a security
wrapper around S-57, which is a complete pain. However, C-Map's Vector
charts are claimed (on the web at least) to be compatible with the S-57
standard. Kelvin Hughes have offered their full support in helping us
understand which Charts we may be able to support. American developers are
OK here as the NOAA has released everything in S-57 which is currently
supported (well, mostly).

Cheers for now,

Tim Brocklehurst

[Openpilot-developers] OpenPilot's Map widget now compiles under Win32!

[Tim B (Software) <ti...@bt...>]

Ladies and Gentlemen,

I just thought I'd let you know that the Map Widget used in OpenPilot will now 
compile under Windows. The method to compile it is documented in the CVS 
repositories, and will be available via the snapshot on the openpilot website 
on Sunday night. This should be exciting news for those who don't have Linux 
systems to develop OpenPilot on. That said, there are still some bugs. Most 
notably, there is no AIS web feed on windows (requires wget to be in your 
path) and no OpenStreetmap feed either. If someone would like to investigate 
these that would be great.

I have noticed that Tom Speer (of forums.boatdesign.net) has been quite keen 
to investigate OpenPilot. Does anyone have a Mac that they could compile OP 
on for him? It *should* be a fairly straight-forward job.

My plan now is to concentrate on writing the documentation and roadmap. Other 
features high up on the priority list are import of GPS from a log file, and 
proper serial port settings (options are already in settings file) to allow 
people to use older NMEA hardware.

Cheers All,

Tim B.
