Open MV Industrial Camera

Hello Team,
I want to use GPIO as trigger to capture frame and do further processing..
Can anyone share how GPIO are accessible via RJ45 port and also the which communication port is available.
It will be helpful if you can also share the simple example

So the RJ45 pinout is as below (here):
1 - 5V
2 - GND
3 - SPI2_CLK
4 - SPI2_MISO
5 - SPI2_MOSI
6 - SPI2_NSS
7 - I2C2_SCL
8 - I2C2_SDA

In terms of accessing the signals, something like this is probably the easiest, unless you'd like to make a custom harness:

And for accessing SPI, see here:
https://docs.openmv.io/library/pyb.SPI.html

And for I2C, see here:
https://docs.openmv.io/library/pyb.I2C.html

Both of those examples are by default setup for the ports mapped above (SPI2 and I2C2).

And the OpenMV IDE has examples built-in for these:

Overall though, it's likely best to move OpenMV questions to the OpenMV forum (here) as we simply re-laid-out the H7 design because Kwabena thought it would be useful to his customers. It was more-or-less a weekend project for us and we're not experts on the system (whereas we are on megaAI and DepthAI).

Anyway, happy to answer questions, but just as a heads up it will probably be out of my depth WRT the OpenMV systems quickly, as we actually haven't used SPI/I2C on OpenMV, we just implemented the hardware to be compatible w/ the existing OpenMV implementations.

Thoughts?

Thanks,
Brandon
