Hi all,
I am hitting a roadblock and thought I'd ask here because I must be doing something wrong. I'm setting up one of these newer waveshare RP2350-Touch-LCD-3.5 boards, and am having an odd issue with the BG color. I noticed it when trying to list the pins. The BG color of the display goes white after the initial print fills the screen, and then each new line is correct (white text on black BG) but turns white on white as soon as it scrolls up. This happens even on a fresh boot with no program loaded.
