Following the instructions in the Seagull manual for configuring ArduPilot to work with the Seagull #REC2, I was successful using the ArduPilot “camera trigger” to trigger video recording - but not for shutter release for still photos.
Of course to do survey/mapping missions, I need to be able to allow ArduPilot to trigger the still photo shutter.
The problem seems to stem from the Sony RX0ii requirement to focus before shutter release.
When I control the channel for shutter with a “slider” or a three position switch, I can activate the photo shutter - because if first goes to PWM of about 1500 which activates the camera focus - then by advancing the slider or going to the third position of an AUX switch - I can then command PWM of about 1800 - which then releases the shutter.
The Sony RX0ii has some limitations compared to more advanced cameras such as the Sony RX100 - but I believe the shutter trigger functions the same.
I’ve asked Seagull tech support for configuration advice - and if they offer a solution I’ll post it here for future reference for others.
In the meantime - if someone has some suggestions - I’d very much welcome the advice and suggestions.
Thank you!
