I'm going through this tutorial :
https://pixhawk.org/dev/ros/getting_started_tutorial
There's this line early on
"We will be using mavlink for passing data between the Odroid and the FC, ..."
but when I read further, it says
"This will test your connection to the Pixhawk and USB camera."
What exactly is implied by connection between pixhawk and USB cam?
Am I using the launch file to
1) Test the connection between my computer and FC, or
2) Test the connection between FC and the camera?
Can I interface a USB camera on the pixhawk? Becuase as far as I know there's only microUSB port on pixhawk, how I would I plug in a USB camera?
