Hi
Nice project!!!
I solved the cv2 and ALSA errors on my Pi4 (I had my sound card turned off with another project)
Now my problem is that program starts, doing 0-180 degrees rotation, turning back and around half way stops and exits the program. I see that on the scope is drawed what is sensed but program exits with this message:
dictionary changed size during iteration
Some advice please?
Thank you

Hi
Nope...did not found a solution.
I suspect that the del at the end is the problem. The variable should not be deleted.
Also the pi is busy doing other stuff this is the reason that working not smoothly. I will try to do it with an arduino soon.
Anyway if somebody solved this issue please share with us.
Thanks and good luck

Unfortunately no,
I have just abandoned pygame and I am trying to work with opencv cv2 as well. It works fine for static image generation, but it does not look like a "RADAR".

Hope you find a solution!

Hey, this error does not come if its ran using python2. If you are using python3 then changing line 78 in display.py to for angle in list(targets) fixed it.
