      Hi, I have tested several value with the lowlight function of veye_mipi_i2c.sh, but it doesn't seem to do anything. Can you please tell me if I have to set other parameters to make this function working ?
      Thanks

        Please follow these steps to test:
        1.

        ./veye_mipi_i2c.sh -w -f lowlight -p1 0x11
        
        1. preview
        2. Completely cover the lens.

        You can see a significant reduction in the frame rate.

          You mean that this parameter cannot be setup on live during preview but must be setup before starting preview ?

            No.
            The above steps do not require a sequence of operations. It's just a piece of advice to see the effect more clearly.

              Yes it does work, thanks, however if I change shutter speed it seems to erase the framerate setting ? Do you confirm ?

                just lowlight setting will affect frame rate if your val is not 0x00 and the environment is in low illuminance.

                  @veye_xumm many thanks, in the VEYE wiki it is said : "value is exposure time(seconds)

                  If value is greater than or equal to 0x4B, it will reduce framerate"

                  So I guess that if you define low shutter speed value it also affect frame rate ?

                  Thanks

                    I think what you mentioned is mshutter. Yes, of course.
                    mshutter :
                    If you use manual mode, the exposure time will be independent of the ambient brightness.
