ESP32-2432S028 display configuration

i used this code for the same screen (usb-c) to fix the same issue:

substitutions:
  LVGL_ROTATION: "0"

display:
  - id: !extend my_display
    data_rate: 20MHz
    rotation: 0

    dimensions:
      width: 320
      height: 240
      offset_width: 0
      offset_height: 0
      pad_width: 0
      pad_height: 0

Hello, I'm still having problems with this type of display. Landscape-mode with 2x3 button-grid works perfectly, but I can't get it to work in portrait-mode 1x4 buttons. To get this display running I need to add

substitutions: LVGL_ROTATION: "0" display:

• id: !extend my_display data_rate: 20MHz color_order: rgb rotation: 0 dimensions: width: 320 height: 240 offset_width: 0 offset_height: 0 pad_width: 0 pad_height: 0

to the additional YAML-file - otherwise I only get noise and a black bar displayed. However, with this modification it's not possible to change the LVGL_ROTATION or rotation to 90°

@ComputerZOO whit my settings I'm able to rotate it 180° from the display settings, at runtime. From what I understand, only landscape is supported for now.

Portrait is actually supported, since screens-v0.2.107 (2026-09-22): a CYD can be built standing up with a 1x4 grid, no manual dimensions/rotation overrides needed.

@ComputerZOO the YAML you added is working around an older, unrelated issue and is exactly what breaks 90° rotation, since it forces a fixed landscape canvas. If you're on a current build (0.2.107 or later), remove that block entirely and instead pick the orientation when you create the screen in ESP Screens: the "New screen" dialog has a portrait/landscape choice, which sets a single LVGL_ROTATION substitution and nothing else. The add-on then knows to lay out the 1x4 grid for that orientation automatically.

If you're still seeing noise or a black bar in portrait without any manual dimension overrides, that would be a real bug, please open a fresh issue with your board revision and the add-on/firmware version so we can look at it separately from this older thread.

Now with the new integration of the ILI9342 https://github.com/MaxGramser/homeassistant_espscreen/issues/50#issuecomment-5853447158 my CYD is working fine.

Thanks @EmanueleBenedettini! This is better suited to a discussion than an issue, so I moved it here: https://github.com/MaxGramser/homeassistant_espscreen/discussions/102

Please continue the conversation there. I'm closing this issue to keep the tracker for bugs and concrete board requests.
