Hi -

 

New Flight Pro developer. Long time Unix, ml, drone developer. No time android developer (!)

Trying to get oriented to this environment and need a few pointers.

 

Question 1: are the snapdragon flight documents on px4 accurate and up to date for snapdragon flight pro?

Question 2: where is the best point to start in building development environment for this great little beast? px4?, navigator?, ???

 

thanks,

  1. I haven't seen any documentation on https://docs.px4.io/en/flight_controller/snapdragon_flight_advanced.html specific to the Flight Pro board. Some of the documentation there (from the old Flight board) will apply.
  2. What do you want to do with the board? Navigator will work out of the box and has a large feature set (I haven't used it personally on old or new flight board), but is closed-source. When I was using the PX4 stack on the old flight board (801 / 8074) for this effort: http://www.genebm.com/#/tango-on-quadrotors/, it worked pretty well, but definitely suffered from lack of development time relative to Pixhawk hardware. Also, to get the aggressive flight performance we needed, I made significant changes to PX4. From that experience, I wrote a new autopilot stack targeted at experienced developers / robotics researchers on the old and new flight boards, using a middleware called F', with a direct connection to ROS. Cross-compile two binaries (one for Linux cores and one for DSP), load both onto the device. There's a ground control station GUI supplied by F' for integration & test, or you can run without the GUI when the vehicle is deployed.

See https://github.com/genemerewether/quest-fw (my repo with multirotor-specific code) and https://github.com/nasa/fprime (general F' framework)

Sorry for the slow reply - for some reason I just got this message.

This sounds like it is ideal for my objective - doing research on combined vslam/gesture recogntion with indoor nav. I appreciate you responding and will check it out!
