I have a RaspberryPi 4B with OV9281 camera module installed.
OS is bullseye (11). I’m using libcamera.
The OV9281 has a synchronisation input pin. I would like to use it to synchronize it to an external source (an arduino that also flashes IR leds).
How can I do that?
I searched for functions in the lbcamera-dev SDK to be able to do that. But can not find any.
Do I have to change a camera configuration file? I can also not find information about that.
I think I did not explain very well. In my situation I have an external piece of hardware that generates the flashes plus a sync signal. So I want to connect this sync signal to the sync input of the OV9281.
I will not connect the flash signal itself. I will make sure the signal level and timing is as needed for the OV9281. 3V3 level high for 1ms? No problem.
But how to configure the OV9281 so that it synchronizes on this input pulse?
When we succeed with this project we will need more OV9281 modules. If there are more types, how do we buy the correct one? And is there an other one better suited for this synchronisation?
I’m here looking for the same thing. The board has the FSTROBE pin broken out which I think it all that’s strictly necessary from a hardware standpoint, no?
Sorry, currently this camera does not work with external triggers, you need to purchase the OV9281 + Pivariety version. If you want to purchase a supported one, you’d better contact [email protected]
