Inverted colors in LVGL?

[kchudoba]

I just set up the CYD with LVGL and in the demos/examples all works but with inverted colors. Any ideas what settings need to be adjusted here?

Did you find solution?

On the User_Setup.h file uncomment one of these lines below:

// #define TFT_INVERSION_ON
// #define TFT_INVERSION_OFF

It works for me and I hope this solution works for you too.

I don't know what LVGL is but I had the same issue with the TFT-eSPI examples. I then noticed that in the main demo examples I tried (the ones in this folder), the colors in the code were also the opposite of what was being displayed. It's a quick hack but adding tft.invertDisplay(1); after tft.init(); fixed it for me. Not sure if that applies to LVGL though.

try this: tft.invertDisplay(1); just behind tft.ini() it will invert coloe order

You probably have the version with the USB-C connector (CYD2USB), so you need to use this config: https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display/tree/main/DisplayConfig/CYD2USB
