Zephyr example/test sketches or projects?

[KurtE]

Sorry, not sure if this is off topic or not.

Wondering if any of you has a repository or the like of example zephyr projects, that you are using
that might help some of us who are starting out on the Arduino side, to better understand how zephyr works?

For example, when you were starting to add Giga Shield support to zephyr, did you have an example sketch to test it
out? Was it LVGL based? Did you test the touch screen... We have some Arduino sketches where, we have some of
the display working with the display using an Adafruit GFX subclassing. But so far I don't think we have a working
touchscreen... (Details about this are in the issue #92)

Examples for your Wi-Fi or BT support?

I am also curious, as to again get a better handle on the usage of Zephyr. I am currently trying Zephyr on some Teensy boards
just to understand the state of it. (Also doing a PR to add Teensy Micromod support to the current support for T4 and T4.1),
but that is a side story...

Thanks

Quick note: as I mentioned in new discussion about building on Windows. We have been playing some using Zephyr directly and
I pushed up a github project with some really rough semi working sketches (applications).

But it would still be great if there are others that are more applicable to the ArduinoCores-zephyr project. Again things like using the GIGA display shield, or using Bluetooth or USB ... And if you are using samples under the zephyr project, which ones? Any special changes needed...

Thanks

@facchinm @pillo79 @iabdalkader @josuah and everyone else:

Sorry, I keep wondering what some of you do when you are making changes to the underlying zephyr system, Such that
it allows others to test those changes out and also make it easier for yourself to test the next changes to that system?

For example, I have a draft pr: zephyrproject-rtos/zephyr#93797
That soon I will probably mark as no longer draft. In this PR, I have updated GC2145 camera library as well as the video_stm32_dcmi code
to allow you to, setup different sizes of output and the ability to use a "SNAPHOT" mode instead of continuous updates.
More details are up on the actual PR.

But the actual question here, is how would you actually test changes such as this? In particular testing it within Zephyr for
Arduino hardware like the GIGA or Portenta H7?

Currently I do not believe there are any of the samples under (zephyr\samples) that are setup for the
GIGA or any Portenta.

Under the samples/drivers/video example I the only sketch that was setup for any Arduino board
was Nicla Vision under capture. And it really did not do anything with the image...

I ended up purchasing one of these and have my own example that then sends the image over USB (Arducam format) to
display it... Which was fun as with the snaphot mode I was able to set the image to 480x320 which is not possible with
released code due to memory constraints. i.e. you are limited to 320x240 (.0768 mega pixel).

Whereas if you had examples setup for Portenta or GIGA outputting to SDRam you can test larger sizes. Also you can test
the stability of the code when you are reading in image onto SDRAM and also processing them at the same time.

Currently I have my own test setup where on Portenta H7, I can output the images to an ST7796 or ILI9341 display.
Which helps test the code as well as demonstrates the issues.

But I keep wondering what others are doing. For example would you test out the impacts of different Pull requests such as this?

Thanks
