I am developing a driver to control a len (step-step motor) using the focuser API and TX2, as you know the motor has a slow response, and the algorithm that nvcamerasrc uses, retrieve value faster than the motor ends to move. I implemented a logic to avoid some of the values from nvcamerasrc (FOCUS_ABSOLUTE control.
At this moment I am able to get the motor moving to the left and right trying to focus but it never gets focus.
My thought is that we need to get a properly configuration for the nv_focuser_config struct in the load config function for the focuser.
Do you know how we can get an slower response from nvcamerasrc through the FOCUS_ABSOLUTE V4L control? (It has been controlled automatically by nvcamerasrc)
I checked your L4T 28.2.1 documentation but I did not find anything related with that configuration. Could you provide us some documentation?
