Hey all, I’m working on detecting Apriltags and then flashing the LED strip when one is detected. I noticed in the terminal printout that there is an error with the Apriltag module relating to something with OpenCV.

I’m not sure if it could be a major issue that could mess up what I’m trying to do, but I thought I would ask and make sure there isn’t something major messed up.

Terminal printout:

Thanks.

It turns out the ribbon cable was creased so it didn’t work. I swapped it out with a replacement and it works just fine now.
