Raspberry Pi Zero Support

[UFFR]

I noticed that the Raspberry Pi Zero W is supported, but is support for the base model planned? I will soon be working on a project that does not require wireless functionality (that and I have already purchased an RPI Zero), and I imagine there may be other people in the same boat.
I don't claim to know anything about the underlying specification differences, but I can't imagine the internal differences between the two, besides one having a built-in wireless chip, being particularly significant.

If you want to test it on the Raspberry Pi Zero, you have to remove the comment from this line: https://github.com/rsta2/libcamera/blob/main/lib/camerainfo.cpp#L19 This should be all. My RPi Zero does not have a camera connector, so I wasn't able to test it. Please report, if it works, so that I can generally enable the device in the repo.

[rsta2]

Maybe. Please also note, that only the Raspberry Pi Camera Modules 1 and 2 are supported. Later versions do not work.

The camera is a v2 (https://www.adafruit.com/product/3099, with adapter cable, of course).

OK, I'm just stupid. I inserted the ribbon cable the wrong way into the camera module. I got it to stream at ~7.5 Hz according to the hello_camera sample. So, the library does work for the base RPi Zero.

[rsta2]

No problem. I added the RPi Zero to the repo. Thanks for reporting!

Random tidbit, is the camera module output expected to look green like this? I'm not surprised the quality isn't that great since it's not attached to any kind of lens yet, but the green tint seems odd. Apologies for the awkward image.

[rsta2]

Unfortunately the Camera Module 2 does not support white balancing in hardware. You have to call pBuffer->WhiteBalance() after getting the next buffer from pCamera->WaitForNextBuffer(). This is already implemented in the sample/ capture_image and can be enabled by pressing the 'w' key.

Thanks, I don't have that much experience with bare-metal Raspberry Pi, let alone the camera module.
