SOLVED Does not working exposure time for manual mode in the CS-MIPI-SC132

duvallee

I'm testing the CS-MIPI-SC132 module for manual exposure and trigger in the Raspberry Pi 4B

As follow, does not work in manual exposure.

rebooting camera module
$ /cs_mipi_i2c.sh -w -f sysreboot -p1 2
set camera stream mode to Software Trigger
$ ./cs_mipi_i2c.sh -w -f streammode -p1 3
set exposure to manual
$ ./cs_mipi_i2c.sh -w -f expmode -p1 1
check while changing the exposure time, but does not applied exposure time.

$ ./cs_mipi_i2c.sh -w -f metime -p1 10
$ ./cs_mipi_i2c.sh -w -f striggerone

$ ./cs_mipi_i2c.sh -w -f metime -p1 100
$ ./cs_mipi_i2c.sh -w -f striggerone

$ ./cs_mipi_i2c.sh -w -f metime -p1 1000
$ ./cs_mipi_i2c.sh -w -f striggerone

$ ./cs_mipi_i2c.sh -w -f metime -p1 10000
$ ./cs_mipi_i2c.sh -w -f striggerone

Hi,

Please read [expostate], this cmd shows the real exposure states.
Please set meagain and medgain if needed.

Look forward to your reply.

I know the problem for metime. After setting the metime, it is applied after 2 frames.
ex)
./cs_mipi_i2c.sh -w -f metime -p1 100
./cs_mipi_i2c.sh -w -f striggerone // old manual exposure time
./cs_mipi_i2c.sh -w -f striggerone // old manual exposure time
./cs_mipi_i2c.sh -w -f striggerone // new manual exposure time (100)
./cs_mipi_i2c.sh -w -f metime -p1 1000
./cs_mipi_i2c.sh -w -f striggerone
./cs_mipi_i2c.sh -w -f striggerone // old manual exposure time (100)
./cs_mipi_i2c.sh -w -f striggerone // old manual exposure time (100)
./cs_mipi_i2c.sh -w -f striggerone // new manual exposure time (1000)

Please let me know how to apply from the next frame after setting the metime.
ex)
./cs_mipi_i2c.sh -w -f metime -p1 1000
./cs_mipi_i2c.sh -w -f striggerone // new manual exposure time (1000)

This feature is not supported now. Because the metime is set to isp, and the isp set to camera.
I think maybe we can set to sensor directly.

Does your application need to change the exposure time frequently and take effect immediately?

duvallee

Thanks for your quick reply.

It may be ok in the free-run mode. But in trigger mode, only received one frame and it processed.
Please tell me how to apply exposure time by directly using sensor register.

An upgrade of firmware will be needed. I will arrange the work, which is estimated to take a week to finish.

Hi, Have you test this upgrade for you?

@veye_xumm
As the time is too long and there is no further feedback from the customer, I will mark this post as resolved.
