Lilygo t-rgb esp32-s3 2.1

ESPHome
1

Hello, I’m trying to start using LilyGo T-RGB-2.1 v1.2 display with ESPHOME but with my current config is not working and I was wondering if someone else managed to make it work.
The config I got so far by searching esphome github & lilygo github related to pins is below:

esphome:
  name: office-display
  friendly_name: office-display
  on_boot:
    priority: 800
    then:
      - switch.turn_off: lcd_reset
      - delay: 
          50ms
      - switch.turn_on: lcd_reset
      - switch.turn_on: lcd_enable

esp32:
  board: esp32-s3-devkitc-1
  framework:
    type: esp-idf
  flash_size: 16MB
  cpu_frequency: 240MHz
psram:
  mode: octal
  speed: 80MHz

After digging deep I managed to work on a minimal config, I haven’t enabled touchscreen on device, because on mine it doesn’t work.

esphome:

    board_build.flash_mode: dio

      -mfix-esp32-psram-cache-issue
