I tried slowrunner’s script on a PI4 with Bullseye 64- bit. Everything is working fine so far. I had read that the 64-bit OS would speed up the Pi4. It did. I am getting 20 fps with cv2. I was getting 13 with the 32-bit os. It seems much more responsive. So far, my bme_280, ps4 controller, pi camera, cv2 and all the GoPiGo parts are working fine.
Much nicer experience on 64-bit.
I think this is the build I am going to use for our NASA fellowships. My final thing to try is the Pi5 and see how that works before I make my final decision.
Thanks slowrunner!
