Hardware Triggering for the CS-MIPI-SC132

ess

Thanks for your reply @veye_xumm and sorry for the late answer.

So we got a fix with our first problem regarding the notifications.
But we are stuck with the Nvidia trigger issue. We are using Nvidea Jeston Nano.
We have stumped upon an example from Allied Vision, but they seem to solve the problem within theyer camera driver.
How have you attempted to fix this issue? Do you thin it is fixable for us without touching the camera firmware? Or do we need your Help with this?

Thank you many thanks in advance!

A small side Note:
Ther is a typo in the CS-MIPI-SC132 I2C.sh user guide at the Trigger denounce section. The listed code is:

./cs_mipi_i2c.sh -w -f triggeredge -p1 enable -p2 [value]
./cs_mipi_i2c.sh -r -f triggeredge

We used:

./cs_mipi_i2c.sh -w -f tgdebncr -p1 1 -p2 [value]
./cs_mipi_i2c.sh -r -f tgdebncr

We could not yet verify in hardware if this works but the readout seemed to work.

Hi, thank you, it is indeed typo.
jetson supports trigger mode, which I have done research on and it has worked. The plan is to organize it and release it along with our new machine vision product line. Estimated 15 days or so.

Our company discussed and decided to bring this forward. It is expected that the version will be available to you within 10 days.

Thank you so much @veye_xumm!
That would be a great help for us! We are kind of stuck.
Do we need to update the kernel then?
We actually have quite a view dozen of your cameras, and are really happy with them.

@ess Thank you for your trust.
Sorry to inform you that we have another recent COVID-19 outbreak on our side. There will be a delay in the timing. But I will push this as soon as possible.

Hello @veye_xumm,

I hope you are well and the COVID-19 outbreak takes a mild course. And you stay save and healthy.
I wanted to tell you that I made a fix work with the Kernel from Allied Vision. It is just hacked together when you update your kernel we will back to switch your kernel.

Greetings ees.
