is the code

error: 'CameraClass' does not name a type; did you mean 'CameraWire'?

There was an undocumented breaking change to the "Camera" library in the "Arduino Mbed OS Portenta Boards" platform release 2.8.0:
arduino/ArduinoCore-mbed@fb07760

The code from the tutorial is a copy of the "CameraCaptureRawBytes" example that comes with the library, so it should be possible to just grab the latest code from the example to update the tutorial.

thanks for the answer, i tried that and it's compiling. But i have another problem now: the Java Processing sketch displays a weird distorted image, like if the video was made from orizzontal stripes, not aligned, then it times out. taking out the not ( !) in this line (if(!timeoutDetected && Serial.read() != 1) return;) of the arduino code solves the timeout problem, but not the distorsion one

Hey @gargoyle777 if this issue doesn't come from our docs site, I would suggest to move this "ticket" to the Core repository.
Thanks

@marqdevx the problem is not in the Core repository.

The problem is with this tutorial:
https://docs.arduino.cc/tutorials/portenta-vision-shield/vs-ard-gs

The source of that is stored in this repository, so the fix must be done in this repository:
https://github.com/arduino/docs-content/blob/main/content/hardware/04.pro/shields/portenta-vision-shield/tutorials/vs-ard-gs/content.md

I missunderstood it, sorry!
We will make those changes, thanks. :)

I should clarify that my comment was specific to the error: 'CameraClass' does not name a type; did you mean 'CameraWire'? error in the original report. That is caused by the sketch in the tutorial being out of date (the updated sketch is here).

I don't know anything about the problem with the image distortion.

Solved at #252
Thanks for the report! 😄
