I have the “Inky wHAT - Large e-Ink Display - Red/Black/White” and it’s not updating any more. I had this hooked up to an RPi3 and I had a script that would draw random colored pixels on the display. I shut it off when the screen was mostly red pixels. I came back to it months later and the script that generated random pixels looks correct in the terminal, but the display doesn’t change. I’ve verified the display is hooked up correctly and firmly. Has anyone else experienced this?
