Re: CPB and GIZMO black screen
The code is completing and exiting. When that happens, things reset and the display can be lost. One way to prevent that is to add an infinite loop at the very end of your code so it won't exit:When run displays.
Code done running,,no errors.
Code: Select all
while True:
pass

It uses the gizmo library (same repo).
