Camera Error in Driver Station
So for the past year, during Stronghold, our driver station was plagued with constant errors coming from the camera that look identical to this:
Code:
ERROR 1 Error when getting image from the camera: invalid image at pos 80871 (0) java.lang.Thread.run(Thread.java:745)
Our robot's code is below:
Code:
