Parrot Bebop Paparazzi Integration

BebopAs you know paparazzi is a very modular platform. To show the world how modular we are, we worked hard on implementing paparazzi into the Parrot Bebop. At the Micro Aerial Vehicle Laboratory (MAVLab) of Delft University of Technology faculty Aerospace engineering (TU Delft) we received a pre-production model of the Bebop. We did our best to have paparazzi integrated before the launch of the Bebop. If you want to follow the progress check our (youtube channel).

Paparazzi Mac OSX release

3 Comments

After a very busy holiday period the Paparazzi developer team are pleased to announce the initial release the Mac OSX port of Paparazzi.

Although this release is a couple of weeks later than expected, the team is satisfied that this port will be easy to install and run. This first release still retains the look and feel of its Linux sibling as currently it uses X Windows for rendering. This is due to change, as the graphics library used by Paparazzi (GTK+) is improving its support for the native quartz engine found in Mac OSX. This improved version of GTK+ is due for release at the beginning of March. The team is tracking this and expect a more native look and feel version of Paparazzi to follow this release.

The porting team has taken particular care to implement the packages as Macport ports thus giving a user the opportunity to install source versions or binary versions. Ensuring that every feature of paparazzi is available as it becomes available.

Again I am pleased to see the depth of talent in the Paparazzi team. Bernard Davison a relative newcomer to Paparazzi development made a huge contribution to the packaging of this port. Enough of the waffle though! The download install page for Paparazzi on OSX can be found at http://wiki.paparazziuav.org/wiki/InstallationMacOSX

Cheers, your Paparazzi development team.

Paparazzi support on Mac OSX: Progress report.

4 Comments

This is a brief note to keep everyone updated on progress towards supporting Paparazzi on OSX. Currently Paparazzi is supported only on Linux. With the growing base of Paparazzi developers it has become possible for us to consider supporting multiple operating systems.

Mac OSX was chosen for attention ahead of Windows 7 due to the its similarity to Linux. We hope that the experience gained in supporting this operating system will give an indication of what form a combined build system for all three platforms will take.

Paparazzi Center on OSX

The GUI used by the Paparazzi ground segment is based on GTK, this provides a transparent way of building X Windows based applications for OSX. To date all the components of the ground segment have been built in this way and function as intended. Unfortunately this currently requires hand building some packages, attention is now being given to simplifying the process by wherever possible submitting patches to the package maintainers.

Once the machinery is in place for installing Paparazzi on OSX without hand building some packages, only a few extra changes will be required to produce a version that uses the gtk-quartz-engines. This will then provide the look and feel of a native OSX application.

A number of interesting facts have surfaced during this process.

The first is that the Paparazzi development team have over the years have been very careful to adhere to the Posix standard. This has meant that very few code changes have been required to make Paparazzi run on OSX. This portability is something the team should be very proud of.

The second is the amazing depth of talent in the Paparazzi development team. I provide only one example of this but there are many more. A central component required in the ground segment is the build system used by Paparazzi to create firmware for the autopilot. This consists of a cross compiler and related utilities. In this case Esden had already done much of the work required to produce such a toolchain with his summon-arm-toolchain script. Thanks to that with only a few “clicks” we ended up with a toolchain that we could use for both of our arm targets, lpc21 and stm32.

It is expected that instructions for installing Paparazzi on OSX with X Windows will be posted at the official Paparazzi wiki in the very near future. With a non X Windows version following in the coming weeks.

And until next time… your Paparazzi team.
