SOLVED no read-out from i2c whitebalance

Seka

Hi,
I am having troubles with variations in supposedly whitebalance and image brightnes.

I changed to same model but different RPI 4B and still use this code:

import D_mipicamera as Dcam


camera = Dcam.mipi_camera()


camera.init_camera()

import os
status = os.system('sh ./veye_mipi_i2c.sh -w -f cameramode -p1 0x0 -b 10')
print status 

status = os.system('sh ./veye_mipi_i2c.sh -w -f daynightmode -p1 0xFC -p1 0x00 -b 10')
#print status 


##turn off automatic exposure
status = os.system('sh ./veye_mipi_i2c.sh -w -f agc -p1 0 -b 10')
print status 
##turn off white balance
status = os.system('sh ./veye_mipi_i2c.sh -w -f wbmode -p1 0x1b -b 10')
print status 



status = os.system('sh ./veye_mipi_i2c.sh -w -f lowlight -p1 0x09  -b 10')
print status 

directory="/home/pi/testmipi/"

date = datetime.datetime.now().strftime("%m_%d_%Y_%H_%M_%S")
frame = camera.capture(encoding = 'jpeg')

camera.release_buffer(frame)
del frame
time.sleep(1)

frame = camera.capture(encoding = 'jpeg')
frame.as_array.tofile((directory)+"nm590"+ date + ".jpg")
camera.release_buffer(frame)
del frame

But I still get different image brightness.
I tried to read-out the whitebalance value with

./veye_mipi_i2c.sh -r -f wbmode -b 10

But i dont get any return value.

What can be the problem?

Do I have to install the camera again if it is the same disk image but another (same model) Pi?

I can read-out the value for mshutter without problems...

Another question: Is there a limit how often I can change the camera settings

I realized that the camera settings have to be set each time that the RPI boots. Is there a way to write the camera settings permanently?

Many thanks

@seka
I can read-out mshuttr, daynightmode etc. perfectly.. only wbmode there is no return.
Just executes the command and nothing

@seka
Please check if you veye_mipi_i2c.sh is the latest version.

Is there a way to write the camera settings permanently?
I'm sorry, VEYE series can not support this.

@veye_xumm Thank you Xu, downloaded the new file and now it is working like a treat!
