Blue and red inverted

[edo44]

I have the two colors inverted for some reason when using LVGL. Any help?

Hi Edo,

You can try to change the MADCTL value. This is currently defined like this (depending on the orientation)
static const uint8_t madctl[] = {MADCTL_MY | MADCTL_RGB}; // Portrait 0 Degrees

so change the color channels to BGR:
static const uint8_t madctl[] = {MADCTL_MY | MADCTL_BGR}; // Portrait 0 Degrees

Let me know if this helps. What are you using as display board?

yep, that solves the problem, thank you very much

Strange, I have also a ESP32_3248S035C and this worked with the MADCTL_RGB settings.
Maybe there are different panels? Maybe need to be configurable in the defines...

This is mine; they look identical. I suspect the LCD panel might be another type....
Maybe some other users can share if they've also this problem?

Hi edo,

Made this setting an optional define and pushed a new version (1.0.4) to PlatformIO.

Enjoy!
