How to initiate display?

ESPHome
1

Hi community!

I have the following issue:
I bought a TFT-Panel with integrated ESP32 from viewedisplay.com,
part-number is UEDX80480070E-WB-A.
I have tried a dozen of configurations to create an output on the screen,
but still failing the gaol.
Now I need some help for an initial configuration of the display.
Is anybody out there who can give me a clue or an example of
source code?
Thx a lot!
Michael

After some testing my code is

psram:
  mode: octal
  speed: 80MHz

spi:
  - id: lcd
    clk_pin: GPIO42 #14
   # mosi_pin: GPIO13
    miso_pin: GPIO12
 

output:
  - platform: ledc
    pin: GPIO21
    id: backlight
  - platform: ledc
    id: output_red
    pin: GPIO4
    inverted: true
  - platform: ledc
    id: output_green
    pin: GPIO16
    inverted: true
  - platform: ledc
    id: output_blue
    pin: GPIO17
    inverted: true

color:
  - id: my_red
    red: 100%
    green: 0%
    blue: 0%
  - id: my_yellow
    red: 100%
    green: 100%
    blue: 0%

    red: 50%
    green: 50%
    blue: 50%
  - id: my_orange
    red: 100%
    green: 50%
    blue: 0%
  - id: my_teal
    red: 0%
    green: 100%
    blue: 100%
  - id: my_white
    red: 100%
    green: 100%
    blue: 100%
  - id: my_black
    red: 0%
    green: 0%
    blue: 0%

light:
  - platform: monochromatic
    output: backlight
    name: "Display Backlight"
    id: back_light
    restore_mode: ALWAYS_OFF
  - platform: rgb
    name: LED
    red: output_red
    id: led
    green: output_green
    blue: output_blue
    restore_mode: ALWAYS_OFF

display:
  - platform: ili9xxx
    model: ili9341
    dimensions:
      height: 480
      width: 800
    spi_id: lcd
    invert_colors: true
    dc_pin: GPIO02
    lambda: |-
      auto black = Color(0, 0, 0);
      auto red = Color(255, 0, 0);
      auto green = Color(0, 255, 0);
      auto blue = Color(0, 0, 255);
      auto white = Color(255, 255, 255);
      it.filled_circle(20, 32, 15, black);
      it.filled_circle(40, 32, 15, red);
      it.filled_circle(60, 32, 15, green);
      it.filled_circle(80, 32, 15, blue);
      it.filled_circle(100, 32, 15, white);

The backlight is working now but there are no circles displayed.

What am I doing wrong?
