SOLVED VEYE -MIPI-IMX462 - how to configure manual shutter&gain

milank

Hi,

I tried to follow the instructions for setting the manual gain and shutter by using the new manual exposure mode. Camera confirms that automatic exposure is not used, both new_mgain and new_mshutter are set.
However, I can see that some autoexposure algorithm is still in effect, is there detailed guidance how the command sequence should look like?

Currently, I am using the script like:

./veye_mipi_i2c.sh -w -f videoformat -p1 PAL
sleep 1
./veye_mipi_i2c.sh -w -f new_expmode -p1 1
sleep 1
./veye_mipi_i2c.sh -w -f new_mshutter -p1 40000 # fixed 40 ms
sleep 1
./veye_mipi_i2c.sh -w -f new_mgain -p1 10
sleep 1
./veye_mipi_i2c.sh -w -f brightness -p1 0x07
sleep 1
./veye_mipi_i2c.sh -w -f contrast -p1 0xa0
sleep 1
./veye_mipi_i2c.sh -w -f paramsave

Please check hdver first.
http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/#new_expmode

The following new features are only supported in versions with release time later than 2022-11-22.

Do not set 'brightness ' if you want to use manual mode.
Pls read those params and check it.

I understood that this is i2c.sh release version, not the HW version.

This maybe needs to be mentioned more explicitelly, to be clear.
This explains the camera behaviour.
Maybe that the script could find out the hw version itself and report if not as expected?
Thank you, anyway.

@milank Sorry this place is not expressed very clearly. This refers to the firmware version of the camera.

Yes, I got it now, no problem. Just ordered the correct one.
I assume FW cannot be upgraded by the user, right?
