I haven’t used my display-o-tron hat for awhile, but I wanted to use it with an enviro-phat I just picked up. It displays fine, but when I run the demo program, the backlight constantly flickers, so it’s distracting to use it. It never used to do this.
I’ve got a pi 3 b+, and downloaded the most recent version of the display-o-tron library. Any ideas why it’s flickering so badly? Everything else seems to work fine.
