[AE-49] No video output for Portenta Vision Shield

[aliphys]

The data sent from CameraCaptureRawBytes.ino sketch uploaded to a Portenta H7 + Vision Shield board is not displayed in the output in Processing 4.2 by the CameraRawBytesVisualizer.pde sketch.

Testing with the OpenMV IDE results in a smooth 60 FPS video feed, suggesting that the Portenta Vision shield in question is healthy.

@aliphys I used to have those issues, until I switched from a windows machine to ubuntu linux and then things were fine.

arduino-libraries/Arduino_OV767X#5

By the way with the Portenta Waveshare grayscale 128x128 OLED is awesome with the Portenta

https://www.waveshare.com/1.5inch-oled-module.htm

I have many sketches that use both on my Portenta Pro Community Solutions Arduino Library (In the arduino library manager just type "community" it should show up)

The github link is here if you want to install it from a zipped file.

The sketches are mainly in the dot35 area but also in the machine learning dot51 area
