      Dear ModalAi Team,

      We would like to know what all other peripherals shall be required with the VOXL2 board to get the flight control setup ready, pls mention all the components related to electronics, add on cards, cables etc. that shall be required to make a table top setup for the same.

    • RE: Dual IMX412 connected to VOXL 2

      @modaltb meanwhile the update becomes available, is there any other method to get a video streamed at FHD@60fps from the voxl2 module over the ethernet interface?

      Hi @modaltb by doing so the voxl-camera-serve and the voxl-portal pumps data over ethernet but on the web portal we are not able to see any vide0 from the IMX412 camera, pls note we are using the same voxl-camera-server.conf file which @Alex-Gardner have suggested to use.

    • RE: Dual IMX412 connected to VOXL 2

      @Hector-Nevarez @Chad-Sweet @Alex-Gardner by editing the voxl-camera-server.conf file we were able to get a video stream from 640X480 @ 30fps up to (1920X1080) FHD @ 30 fps resolution for both the IMX412 camera, as seen from the datasheet the IMX412 sensor is a 12.3 Megapixel sensor and we would like to acquire highest possible resolution video stream from the sensor at 30fps as well as 60fps. Can you please let us know how this can be achieved.

      P.S. In the above mentioned conf file if we provide any resolution over and above 1920X1080 the video pile line crashes.

    • RE: Dual IMX412 connected to VOXL 2

      Hi @Alex-Gardner I guess the voxl-configure-camera was overwriting the voxl-camera-server file, bypassing that allowed us to get streams from both the IMX412 camera via the voxl-portal command.

      Refer Following image:

      0a9b0915-8b9e-4c82-bc13-377c048102a9-image.png ![alt text](image url)

      The required part of getting two parallel streams from 2 IMX412 camera onthe VOXL2 board seem to be achieved. I case of any further doubts on this activity will open a new thread. Thanks for your support.

      To add to the above point the voxl-camera-server.conf file goes back to the default setting once the module is power cycled, refer following snapshot of the same file post power cycling.

    • RE: Dual IMX412 connected to VOXL 2

      @Alex-Gardner Thank you for the clarification, pls refer following screenshot of the updated voxl-camera-serve.conf file from the VOXL2 module.

      {
              "version":      0.1,
              "cameras":      [{
                              "name": "hires1",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    0,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       640,
                              "snapshot_height":      480
                      }, {
                              "name": "hires2",
                              "enabled":      true,
                              "frame_rate":   30,
                              "type": "imx214",
                              "camera_id":    1,
                              "preview_width":        640,
                              "preview_height":       480,
                              "snapshot_width":       640,
                              "snapshot_height":      480
                      }]
      }
      

      Once the above file as updated we carried out the suggested steps by providing the command
      voxl-configure-cameras, as stated in my earlier post there are variety of options which pop-up once the command is executed, can you please let us know which is the appropriate configuration id to be selected from the following drop down:

      available camera configurations are as follows:
      
      0  None
      1  Tracking + Stereo(OV7251)
      2  Tracking Only
      3  Hires + Stereo(OV7251) + Tracking
      4  Hires + Tracking
      5  TOF + Tracking
      6  Hires + TOF + Tracking
      7  TOF + Stereo(OV7251) + Tracking
      8  Hires Only
      9  TOF Only
      10 Stereo(OV7251) only
      11 Tracking + Hires + Dual Stereo(OV7251) Pairs
      12 Stereo(OV9782) only
      13 Hires + Stereo(OV7251)
      

      We have already tried out the following all camera configurations option so far and only in camera configuration id 8 we are able to get video but the video is only from 1 IMX412 sensor.
