      The longest exposure time is when I use

      a) lowlight = 0x11
      b) mshutter = 0x53
      c) videoformat = PAL

      Then the exposure time should be 1/30 * 25 = 1.2 seconds.

      Is this correct?

        For VEYE series, the longest exposure time is 1 second.
        For CS-MIPI-IMX307, it is 7 seconds.

          @veye_xumm thank you for the fast reply. I have a board VEYE-IMX385 using it with RPi / Buster. The settings configured with veye_mipi_i2c.sh seem to have no effect on any preview or still image generation. It always seems to set exposure time and frame rate automatically.

            @veye_xumm in addition I now made a new installation with Bullseye and v4l2 mode. When I use VLC for preview the camera control changes with veye_mipi_i2c.sh do apply to the preview.
            I do not understand. When using Debian Buster with driver with it's standard camera driver the veye_mipi-i2c.sh control commands do not have an effect?

              @veye_xumm and one more question: the c_demo codes obviously do not work in Bullseye with V4L2 drivers. Are there any c-demo codes for using the camera without any third party application (e.g. VLC, gstreamer, etc.) ?

                Please use ./ camera_i2c_config to control the camera's reset pin first.

                    @veye_xumm thank you for your answers.
                    Is there any chance that the IMX385 sensor will be available with a CS-MIPI-IMX307-like board? I would like to have longer exposure time with sensor IMX385.
