Hi there,

Two things to try
First one: update the firmware

Second one: try to increase HTS
you can try to increase HTS while the camera is running, the steps are as follows:

  1. Get the current HTS

python3 rw_sensor.py -r 0x380c 0x380d


  1. Increase HTS

python3 rw_sensor.py -r 0x380c 0x380d -v 0x03 0xD8

FuzzyBoundariesAndRubbishOnRightThat helped a bit, but the edges are still fuzzy and there is a black bar on the right. The first image is 1/4 width, but the next three at ~10% to narrow

It seems something is resetting 0x380c.

  1. If I initially read it I get 0x02.

  2. Then I set it with your command
    python3 rw_sensor.py -r 0x380c 0x380d -v 0x03 0xD8
    and it echos the correct value.

  3. If I read it again it is back to 0x02

When I connected the four cameras to a RPi they worked great, so it is something in the software or setup.


Please make sure to turn on the camera before modifying the register value.
First run python3 arducam_displayer.py
Next run python3 rw_sensor.py -r 0x380c 0x380d -v 0x03 0xD8

After you confirm the available value, we can update the firmware to avoid manually setting this value every time.
