Due to an issue with Linux kernels, the drivers for the PS3Eye are no longer supported. If you would still like to use the PS3Eye, you can downgrade your kernel with the following command:
sudo CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt rpi-update 866751bfd023e72bd96a8225cf567e03c334ecc4. Note: You must be connected to the internet to run the command.
The logic for controlling LED mode when multiple cameras are connected is not fully fleshed out. In its current state, LED control is only enabled when a Pi Camera Module is not in driver mode—meaning a USB camera on its own is unable to control the LEDs.
For now, if you are using multiple cameras, it is recommended that teams set the value of the NetworkTables entry
photonvision/ledMode from the robot code to control LED state.
