I want to working Camera Trigger & Capture
but does not woring…
FC : CUAV V5+
TRIG_MODE 4 (distance - survey mode)
TRIG_INTERFACE 4 (IR PWM)
TRIG_PINS: 6
I think that AUX6 pin output pwm 1500
1500 is default setting value
and if i want shutter with GCS(Qgroundcontrol), AUX 6 pin output 1900(default)
but AUX 6 don’t output anything value
I try to any another FC
example : CUAV V5 Nano, Orange Cube
Evrything does not working
Are there any other parameters that need to be modified?
if not
Are there any other parameters to activate?

@GriTRini I think there are two things here - Is the camera trigger not working or the camera capture?
How are you testing the interface?
Can you share the log of it not working?
I does not working camera trigger
I setting TRIG_PINS: 6
and I connected the AUX6 and the oscilloscope to see how the signal came from the AUX6.
I test Camera shutter response with pwm.
Pwm is setting RC AUX2.
Camera’s response is normal.
but if i change camera trigger, did not working and didn’t output pwm.
What’s the problem??
I know problem
Problem is airframe.
I select standard vtol. but this is not working
Hi @GriTRini @Jaeyoung-Lim , have you solved this issue yet? I faced a problem with the camera trigger too. Firmware v1.13.1, Airframe standard vtol, FC: pixhawk 4 and cube orange. Trigger did not work for both GPIO and Seagull PWM. I have experience setting up these before using firmware 1.12.3 However, everything works fine, so I think this is firmware/software bug
@saengphet Please provide either a log or more information what you have tried, how it is failing.
Just stating that it is not working is not enough information to diagnose what the problem is
In the Linux program (git clone GitHub - PX4/PX4-Autopilot: PX4 Autopilot Software --recursive), type the command into the terminal and download it (bash./PX4-Autopilot/Tools/setup/ubuntu).sh) Type this command and then make build according to your FC. For example, type (make px4_fmu-v5_default) if pixhawk 4 or (make px4_fmu-v3_default) if pixhawk 2 orange
If you don’t succeed, tell me and I’ll share the file.
@GriTRini Have you tried configuring the camera trigger?
Yes, I have but not working so i changed firmware and solved

@GriTRini So it is working now? How did you configure your camera trigger? This information is not included in the instructions you have provided

it is setting AUX 1~5 with pictch, roll, throttle, rudder and it don’t active AUX 6
so it is not working pwm and i don’t change AUX 1~5
I think, it is working only commander
but px4 github master active allocation. so i can use cameratrigger
I can reproduce and confirm that the current master (22-nov-2022) seems to fix this issue. I wonder what the PR relates to this issue, I will try to merge it into v1.13.1. Because the UAV has already passed the flight test in MISSION mode. I don’t want to use the current master to avoid software bugs or unknown cases. @Jaeyoung-Lim @GriTRini
