The official product documentation is located at https://docs.modalai.com/

The purpose of this forum is to supplement that documentation, and to update the official docs when we find information missing.

Little more detail, we've validated with FrSky X8R reciever and Taranis X7 transmitter with the following setup:

We have a new cable about to come out to assist with this wiring as well:

@Pey-Astig Yes it's possible. We'll have some docs up in a few days but connecting via USB to the flight controller, setting airframe to HIL, and adjusting these settings should get you going:

Hi Andrew,

We have other folks using it for controlling ESCs, let me try to see what I can find as far as examples, we don't have one in our repos.

PX4 itself has a UAVCAN implementation they've been working on that might be of help: https://dev.px4.io/master/en/uavcan/index.html

Thanks!
Travis

Hi @rapit ,

We don't have a VOXL version going yet, but this should be close: https://github.com/ATLFlight/dfs-ros-example

@Chad-Sweet ping!

The ModalAI YouTube channel can be found here: https://www.youtube.com/modalai

It has lots of good tutorials and demos.

Using this as reference: https://docs.modalai.com/voxl-cam-ros/

These scripts use some environment variables that have tripped me up before, for tracking:

https://gitlab.com/voxl-public/voxl-cam-ros/-/blob/master/launch/tracking.launch#L7

Can you run voxl-env show ?

TRACKING_CAM_IDneeds to match that of the launch file.

You can use voxl-configure-cameras to modify if needed.

Thanks for the post! You are user #1

We made a change to voxl-vision-px4 some time back and I'm wondering if you are caught in the middle.

"Older" (a few months back) version of the program expected all traffic over port 14550, since then we've split up traffic for 14550 for external clients (e.g. QGC) and 14551 for onboard traffic.

Notice here we are using 14551:
https://gitlab.com/voxl-public/mavros_test/-/blob/master/run_mavros.sh#L7

I wonder if updating this on your system to 14550 will get you going?

The other option is to update the system image and then software suite to get the latest, if this is an option let me know.
Thanks!
Travis

You can control the cooling fan following this:
https://docs.modalai.com/voxl-fan-control/

VOXL has a RGB LED, shown here, and can be set via code running on the apps processor:
VOXL Datasheet - LED

VOXL-Flight has a few RGB LEDs, 2 of them are controlled via PX4 (STM32), but the other one can be controlled via the apps_processor as well (labeled LED3 here):
VOXL-Flight Datasheet - LED3

To control this LED, you can follow instructions here:
