Multiple Lidar Lite V2

Posted by Peter Skotte on November 19, 2015 at 4:34am

Hi there.

I am in process of setting up a quad that need to fly with 3 Lidar lites in a circular array.

See example here:

I know how to wire up 1 sensor to the pixhawk, but I don't know how to add 3, and how to setup them up in mission planner.

I hope for some assistance from the community ;-)

Thanks,
peter

Hi, tell me, please, do I need to make any changes to the code of the ardupilot, and how to configure this multiplexer for pixhawk?

I want to connect 4 lidars VL53L0X to the pixhawk so that it is possible to organize a circular system of collision avoidance, tell me, please, how to do it correctly with PCA9547?

Any news about this project? It's very interesting.

No one? :-(

  I'm not sure why you're getting no support on this question. May I suggest that you PM someone like Tridge or Randy. They are very busy guys but they both have extensive experience integrating the LL into the Pixhawk.
  
  In the near future there will be UAVCAN bus LiDARs available precisely for your kind of application. This will allow for any number of units on a single bus and Pixhawk already supports UAVCAN .
  
  Good luck! :).

    Thanks, I have just reached out to Randy.

        Unfortunately not. I am kinda stuck. I have made the HW setup as show for the Arduino with multiple sensors. But I have no idea how to make the pixhawk address the 3 different sensors (I guess they have the same HW id?) because I can only get one to show up.
        
        So any help on this matter is much appreciated ;-)

        Have you tried looping through each sensor as if it is one, by taking a reading of the data from each and parse it. That way, the Pixhawk thinks it's addressing one, but the Arduino accesses each in a loop. Not sure if the Arduino and the Pixhawk can do this, but it's an idea. Good luck.
