[caballero03]

I am experiencing the same error message on the ESP32-2432S028R display. Did you find out what is wrong?

[rzeldent]

Found out a bit: See #222

Hi caballero03,

I just retested the ESP32-2432S028R that I own (with USB-C and USB-micro) and this works using the esp32-2432S028Rv3 definition.

Can you give this a try?

[caballero03]

Hello,

It does appear to work with the v3 definition, however, the screen is mirrored. The touch screen seems to be in the correct orientation but doesn't match the position of the mirrored display elements. The buttons and LDR readings do work. Only mirrored display.

See here in photos:

Okay, some progress! But also the colors are not right. These are BGR and mirrored.

Play around with the setting for CONFIG_COLOR_SPACE and mirror...

[caballero03]

I did get the mirror setting proper now with DISPLAY_MIRROR_X=true. Now the buttons activate on the same spot as the button. Looks like the TOUCH_MIRROR_X was mirrored in the original config but not the display.

Not sure what the colors are supposed to be. I tried changing the:
ST7789_DEV_CONFIG_COLOR_SPACE=ESP_LCD_COLOR_SPACE_RGB
to:
ST7789_DEV_CONFIG_COLOR_SPACE=ESP_LCD_COLOR_SPACE_BGR
but it didn't like that.

Progress indeed. Thanks for this bit of encouragement and excellent advice.
