LidarLite working correctly? - SOLVED

Posted by Felix Meissner on April 28, 2015 at 3:40am

I am trying to set up a LidarLite sensor from PulsedLight.

I set it up according to the wiki (new sensor, manufactured Feb 2015, interfaced with a Pixhawk)

http://copter.ardupilot.com/wiki/common-optional-hardware/common-rangefinder-landingpage/common-rangefinder-lidarlite/

In the wiki it points to the Flight Data Screen to test the sensor,

but I only get zero as reading in this window.

But if I check in the terminal,

I can see that the sensor is working (see attached file),

so is it working ok? Is the wiki wrong?

Thanks a lot,

Felix

Hi

this is the answer from PulsedLight:

You’ve contacted PulsedLight Inc’s LIDAR-Lite help. PulsedLight was recently acquired by Garmin International and is working to transfer engineering and production to Garmin.

LIDAR-Lite will be in production again. Please check our website for updates.

I was hoping some of you might have more information about what is happening with the Lidar-Lite products?

LIDAR-Lite v2 has been marked EOL.

They were bought by Garmin recently: Garmin® Completes Acquisition of PulsedLight®

Is there any information available about the status of their current and future UAV products?

Thank you,

LIDAR-Lite v2

This is the LIDAR-Lite v2, a compact high performance optical distance measurement sensor from PulsedLight. The LIDAR-Lite "Blue Label" is ideal when…

  Robot shop was showing V2 as back ordered, still I went ahead and ordered it hoping to get it when it is back in stock. This was quiet a while back. However few days back I received a mail from robot shop stating that V2 is no more in production and garmin is working on V3 which will be available soon.

      how do you supply the 5V to the Lidar sensor?
      Can you maybe double check that the power supply is ok?

  Interesting. I am flying a LidarLite V1 on PWM with AC 3.3.2.
  Measurements are pretty exact and I don't want to miss it anymore
  I also tested a LidarLite V2 on I2C with the same Pixhawk running AC3.3.2 with similar (correct) measurements.
  I have also set
  RNGFND_SCALING = 1
  RNGFND_OFFSET = 0
  as you did.

So PWM is the way to go for now it sounds like even with the v2.

Has lidar been tested with 3.3 stable?

Is any one using lidar and optical flow- PX4flow- successfully?

  I got the lidar connected via PWM and it is giving readings on the sonar range line.
  
  Do I need to set a flight mode to use lidar or does it automatically over ride the barometer in the flight modes?

    the Lidar is used in flight modes which have height control, such as Altitude Hold, Loiter and PosHold Mode.
    
    The data from the sensor will be used until you exceed RNGFND_MAX_CM, after that it switches to the barometer.
    
    Currently Lidar is not supported in Auto Mode.

      Thank you, that info helps a lot.
      
      When I read throught the arducopter lidar set page I did not see this important piece of information. Maybe it should be there in one of the highlighted bubbles so it can not be easily missed.
