@Alex-Kushleyev Found the reason why it was skipping. In /px4-firmware/src/lib/parameters/CMakeLists.txt there is a line that skips all modules that match 'pwm_out'. I was able to disable that for PCA9685. Once I disabled the module.yaml file being skipped it worked. No need for the .c file (which makes sense, that is just the old way to do the .yaml)

I'm trying to do the same: create a Kicad symbol for VOXL 2 as a module (ie, no internal details, just interfaces). Have you had any luck in locating something?

Best,

@Alex-Kushleyev sure thing. As per your suggestion, I modified voxl-lepton-server by moving all the Lepton camera-specific logic into a C++ class and added locks to any I2C operations to prevent race conditions. I then just created 2 instances of the LeptonCamera class I made which parse and publish the camera feeds to their own pipes which I can view in voxl-portal.

I didn't need to disable any I2C interface for the second Lepton. I'm not too sure what you were referring to by that.

In regards to the horizontal line artifacts, those don't seems to consistently appear and I don't know what causes it. I'll investigate it further.

My next steps are to get the Leptons working with voxl-open-vins-server. One question I had was that our VOXL 2 Mini appears to be running a service called voxl-lepton-tracker however I cannot find the source code for this anywhere on the voxl public GitLab. Was it removed or hidden?

@cbay ,

As long as the Boson / Boson+ 640 (or 320) supports MIPI output, it should work. We believe that some Boson models do NOT have MIPI support (HW limitation) but all Boson+ do have MIPI support. Please check with your vendor to make sure MIPI output is supported.

Also, did you actually mean M0187, or something else? M0187 is an adapter for a Flir Lepton : https://docs.modalai.com/M0187/

@cbay ,

We support any camera that is compatible with UVC (plugged into a usb port). Please look into voxl-uvc-server. https://docs.modalai.com/voxl-uvc-server/

Regarding NIR, have you considered using a regular camera (most cameras are sensitive to NIR) and install a lens with a NIR pass filter (if you dont want to see visible light)? Then you could use one of our hi-res cameras like IMX412 or IMX664. I can get you spectral response plot of those sensors if you need.
