Hello everyone,
I have accidentally turned my camera 180 degrees. Turning it round does not work because it is firmly attached to a bracket.
How can I rotate the video stream 180 degrees again? Where can I configure this?

Best regards,
Tom

@TomP Wonderful! So glad to hear. And I would really love to hear how the flight testing goes. We've never tried a VOXL 2 (or VOXL 2 mini) on a fixed wing (with ArduPilot) so be careful and triple check to make sure everything looks setup correctly before launching.

It is an honor for me to report. We will be careful. Of course, a crash can also occur independently of the VOXL2. This is a new drone that we are building.

What might be relevant for you is that we have found a gimbal that will fit one of your cameras with a bit of hardware hacking. The gimbal can also be controlled via serial interface using Ardupilot. We have already successfully tested this with the VOXL2-Mini.

voxl-2-io

It works! Many thanks for the great support!
The firmware upgrade was the solution.

@Eric-Katzfey said in ArduPilot on Voxl2:

@TomP A new voxl-ardupilot package with debug information added. But we may not need that. Try voxl-2-io detect and then if that is successful then try voxl-2-io scan

@Eric-Katzfey said in ArduPilot on Voxl2:

Yep, that all looks fine. Shoot. I may need to send you a new package with extra debug information to help debug this since by default there really isn't much we can see.

What do you mean by that?
"a new package with extra debug information"

@Eric-Katzfey Here is the pin configuration (J19 on VOXL2-Mini to J4 on IO Board):

VOXL2-Mini-----IO Board
9-----------------1
8-----------------3
7-----------------2
6-----------------4

(I mistyped the table at the beginning. I have corrected the typo.)

@Eric-Katzfey I can rule out connection problems. I checked the contacts on the VOXL2-Mini and the IO board with a continuity tester. Everything is well connected.

I know that with ardupilot you can at least control the servos without arming. Is this perhaps implemented differently here? Then I would have to calibrate the sensors etc. to test this.

@Eric-Katzfey Here are my settings (no PWM output):

SERVO1_FUNCTION,4
SERVO1_MAX,1900
SERVO1_MIN,1100
SERVO1_REVERSED,0
SERVO1_TRIM,1500

@Eric-Katzfey The battery monitor works. Thank you very much! I'm sure the PWM will also work and then it's off to the test flight.

Hi,

There is another problem. The PWM board does not output PWMs. I have also measured this with an oscilloscope. According to SERVO_OUTPUT_RAW, however, the FC should output PWM values.

Do I have to set another parameter in Arduplane so that the VOXL 2 I/O Expander Board is controlled correctly?

I use the VOXL2-Mini J19 connector: GND, pin 7, pin 8 and VREG_3P3V_RC for the power supply.

Here is my setup:
