Support for lightning version

[izzerialthedevil-ghf]

Hello!

Thank you for this software! Can you help me with my problem?

This errors after starting camera in InfiRay Viewer.

I'm trying to use the Lightning version of P2Pro, connected to a MacBook Pro 2019 (macOS Sequoia 15.5) with a Pergear Lightning to USB-C cable (this setup works fine, tested with an iPhone 16).

I'm using the included lighting to usb-c adapter and I see the same problem. I assume it has something to do with the lightning bridge and requires some additional code.

I'm using the lightning version as well.

Does the camera show up when you plug it in?

You should be able to open up QuickTime and see it as a camera.

Nope does not show up as a camera. Which Lightning-USB-C adapter are you using? I am using the one that came in the box. Are drivers necessary?

This is all I see when it is plugged in:

P2 Pro:

  Product ID:	0x5840
  Vendor ID:	0x0bda  (Realtek Semiconductor Corp.)
  Version:	0.02
  Serial Number:	0000000000052333
  Speed:	Up to 480 Mb/s
  Manufacturer:	infisense
  Location ID:	0x01100000 / 1
  Current Available (mA):	500
  Current Required (mA):	100
  Extra Operating Current (mA):	0

I've done some investiaging. The messages in the log are unrelated to the problem you are seeing. Apparently they are just log noise.

I've fixed the error reporting in the app - I suspect that it is not finding the infa red camera.

I'll need to check when I am back home to see if something has changed in the operating system.

But when you plug the camera in it should show up as a "UVC Camera" if it doesn't and if you can't access the camera with any other tools then we're pretty stuck.

[cgreening]

Actually - I've just remembered - I'm actually using the USB-C version. Not the lightning version.

So the initial guess was correct - it's to do with the lighting to USB-C converter.

With the device not showing up as a camera there isn't much we can do. If you open up quicktime and select

File->New Movie Recording

Does anything show up in the list of cameras?

[cgreening]

I've added some code so that it dumps out a list of cameras that it does find. You should see something like this in the logs:

Found the following cameras:
	OBS Camera Extension
	iPhone13,3

Note - it only finds "external" cameras.

[dbavatar]

No new cameras appear with the lightning adapter.

That's a shame - without some help from InfiRay we're going to struggle to make progress.

This is likely a matter of protocol differences. USB-C version recognized as a standard UVC device and Lightning version uses some Apple-specific protocol, MFi certified.

The only way of "converting" a USB-C version to Lightning would be to dump the SPI flash from a Lightning version and flash it onto a USB-C version and vice versa for converting the other way around.

In theory it could be possible to have both version on the same flash and jump to the respective one in the bootloader, based on some trigger (eg. if some pin on the SoC is tied low).

It would be interesting to have a dump of both versions to compare, so if anyone is up for it...

The SPI flash can be seen in this teardown video.

I'm assuming the only differences between the two are:

• USB-C / Lightning port (exchangeable as it's on a connector with a flex cable)
• SPI firmware
• Slight chassis difference due to Ligthing/USB-C port being difference size

Seems also that the SPI pins may be accessible from test points on the PCB, if feeling uncomfortable using hot air on it. Seems the flash chip package is USON-8 (by looking at the video).
