I just finished the BlueROV2 Heavy build, with 4 Lumen lights and the Newton Gripper. I am having three separate issues.
- It appears that one of the servo leads is plugged into the Pixhawk backwards (but I want confirmation).
- The tilt for the camera does not work.
- The video on QGroundControl intermittently gets blanked out with a gray screen.
Problem 1. Attached is a picture of the Pixhawk inputs. It appears as if there is a servo lead plugged into Aux 6 upside down (the signal is connected to the ground rail, and the ground is connected to the signal input). Am I correct, or is the wire color convention ignored on this particular servo lead? I would just flip it around, but want confirmation that it is incorrect first. What is this servo lead connected to?
Problem 2. The camera gimbal is setup on channel 10 by default. But will not move when the joystick button assignments are setup per the list for the Newton Gripper (Button 9+shift=mount_tilt_down, Button 10+shift=mount_tilt_up) I have screenshots from Widgets>Mavlink Inspector that might help. (RC Channels Raw, RC Channels, Servo Output Raw 1, Servo Output Raw 2). The Servo Output Raw 1 and 2 show two different versions of the same screen. servo9_raw through servo16_raw shift back and forth between, what appear to me to be nonsensical values represented in these two images.
Problem 3. The last problem is that my video feed intermittently turns gray for a second, and then reverts to normal video, and continues this cycle as long as the ROV is plugged in. I have included a video of this behavior. I did not think to look to see if the timing of the interference coincided with the strange value shift in the widget Servo Output Raw.
Any help that you can give would be greatly appreciated.
