Companion: Pi 2/3/Zero

A discussion page to allow me to add my experiences using a Raspberry Pi 2/3/Zero V1.2/1.3 as a companion computer for Ardupilot/APM/Pixhawk flight boards. I will update my experiences as I learn, feel free to comment and offer tips, it's all free here.

I'm building a github for my experiments: https://github.com/benb0jangles/Companion-Pi

Ardupilot Technical Questions:

Also, if you have any technical code/hardware questions which you feel may take ongoing contributions and help over an extended timeframe, feel free to ask over on Ardupilot.org technical discussion page herehttp://discuss.ardupilot.org/t/companion-pi-2-3-zero/9460

I will update as I get by, please contribute by offering your 'plug & play' wifi adapters using Raspbian Jessie. Also, if you happen to pick up this project, and are working faster than me, then please send us your own .img file experiments. Thanks.

    • Wow really? I thought injection wasn't working on any AC adapters?

    • Fnoop, I have not tried injection, just reading iw list output...

  • I think there is good potential for making many different .img files available for users. I just got some new goggles with hdmi-in 1080p resolution, and I'm thinking how good they would be with a rpi zero attached streaming 1080p. I wonder if @Patrick Duffy has a QTGstreamer version for Linux/Raspbian? I would probably just explode if that happened as it would set off a whole drone racing HD digital revolution. Such potential!

    • Can you give an first hand  impression of the those goggles?

    • yarp. I really like the HDMI in potential, my review here: http://dalybulge.blogspot.co.uk/2016/05/comparing-diy-goggle-to-ret...

    • @Ben,  It's possible to build a Raspbian version of the HUD.  Android version is actually the most difficult, so Raspbian should be fairly easy in comparison.  Give me a few days and I'll see what I can do. 

    • let me know if i can help. I'm not experienced compiling software (you use QT?) but I can test/bug check

      Qt | Cross-platform software development for embedded & desktop
      Qt is the faster, smarter way to create innovative devices, modern UIs & applications for multiple screens. Cross-platform software development at it…
    • Yes, it's Qt.  I have Qt running on the PI already, but it will take some work to build QtGStreamer on Raspbian. 

  • I also have a hummingboard which runs android, so perhaps I could test qtgstreamerhud.apk on that connected to my goggles for HD digital video + Telemetry HUD :)

  • @benbojangles thanks for all your documentation. It has been interesting reading. I have been on a similar venture using rpi for streaming video and also telemetry back to android phone running tower. I also have a http Post server running on rpi that I can issue commands to from android app to stop/start video streaming etc. Hopefully I get some time to put detail here.
