One comment on that. I have an OpenPilot board sitting here and know the
onboard and offboard codebase at least ok, if not well. Its a great project and
I'm happily using it.
However: OpenPilot has a kind of "shared memory" architecture between GCS and
autopilot.
If you change an onboard data object in only one variable -> Complete re-build
of the GCS
This approach works nicely for OpenPilot. It is however about the worst-case
for a multi-project use of the GCS, since it effectively forces you to use the
very same data containers. And since the data containers are even used on the
UI level, changing the protocol forces you to update the UI code.
The difference between QGroundControl/MAVLink and OpenPilot is that MAVLink and
QGC have one abstraction layer on each the autopilot and the GCS side. So the
user interface can be changed without effects and the onboard code can be
changed without side-effects. OpenPilot misses these layers in the onboard code
and in the GCS.
So it is very elegant for a single project. But its the opposite of
standardized communication - I've even added MAVLink support for the OP board
I'm using for this reason.
So don't take me wrong, nothing against OpenPilot, I'm happily running a board
with OP on it and I'm partly using the GCS. But for a multi-project use, this
is a dead end.
Please also note that the OP GCS has a weak mission support (I haven't seen a
waypoint list at all so far), so I'm not sure how this will work out for the
very advanced concepts the PPZ community is used to. Other GCS like APM
Planner, HK GCS or QGC are also not on the PPZ versatility level, but they at
least support takeoff / landing / loiter waypoints and actions like relay
firing, with more MAV_CMDs to come:
MAV_CMD reference: http://pixhawk.ethz.ch/wiki/mavlink/
And on a personal note: I really think there is a need for a standardized, open
and not project-owned protocol out there. APM and Pixhawk are already sharing
MAVLink and with QGroundcontrol, APM Planner and HK GCS there are several
options available (QGC runs on all three OS, APM Planner on Win and Linux if I
remember correctly).
And there is even Android support:
http://diydrones.com/profiles/blogs/copter-gcs-with-mission-support-and-more.
After Paparazzi strived for openness so long it would be sad to see this
opportunity pass to really have joint protocol in the community.
Cheers,
Lorenz

I would like to have your feedback about the ideia of modifying the openpilot
GCS software to work with paparazzi boards.
We have the authorization from openpilot people to do it.
It's an highly customizing platform and appears to be easy to work. Almost
everything is in C++ language.
It can work on linux, windows or MAC OS and permits to create installation
files. So, it's very userfriendly for some end users.
What you think?

Hello Bernard,
How is the paparazzi center for Windows?
Did you saw the CGS of openpilot.com<http://openpilot.com/> project?
www.openpilot.com<http://www.openpilot.com/>
I tried and it's so user friendly and it's great for the end users. It would be
very nice to do something like that.
I can help. What you think? Have something working on windows right now?
The openpilot CGS is C++ language.
Best regards

The development process has started and the documentation also started but I
haven't got as far as Eric yet.
I've been stuck on some other tasks but should be back onto it in a week or two
tops.
Keep an eye on http://paparazzi.enac.fr/wiki/Installation/Windows
Note that I would not recommend anyone follow the instructions unless they want
to help out Eric and I in making the system work.
Cheers,
Bernie.
