I am havi9ng trouble with the wio term display. I’m on my 3rd board. Display on # 1 was bad out of the box. # 2 worked for a few hours before failing. Number three locked up after loading the display diagnostic example. They turn on/off (i.e backlight high/low) but will not display anything on the screen other than grey.
It’s possible its a hardware problem, but I’m thinking its a driver/library issue. Has anyone used a tft library beside the ESP one?
