Hi

I have problem to get my screen working on this. I have tried alot of diffrent configs.
Its a esp32-2432s028 with dual usb (micro/usb-c).

Anu suggestions?

Looks like a sunton-esp32-2432s028R with a resistive touch screen. Resistive touch doesn’t work that well but this file should get you going.

Or openhasp

Thanks I will try this code and check on yours

Hi everyone thanks for all help. I manage to get it working I just had to add “color_palette: 8BIT” under display section.

Interesting. I have one of these screens and I did not need to add that to get it working.

Can you post your final working configuration?

Yes I just made alot of testing diffrent examples

display:
  - platform: ili9xxx
    # model: tft 2.4
    model: ili9342
    color_palette: 8BIT
    spi_id: tft
    cs_pin: GPIO15
    dc_pin: GPIO2
    rotation: 0
    invert_colors: true
    id: cyd

Does this work? That is what works for me

display:
  - id: my_display
    platform: ili9xxx
    model: ILI9341
    spi_id: tft
    cs_pin:
      number: 15
      ignore_strapping_warning: true
    dc_pin:
      number:  2
      ignore_strapping_warning: true
    invert_colors: false
    update_interval: never
    auto_clear_enabled: false

I will try that

You’ll want to add:

lvgl:
  buffer_size: 25%

It’s not likely to work with the native display lambda functions.

Righ I have that in my config
