@ashald Please integrate changes.
After merge will be (hopefully) fixed error:
File "/config/esphome/.esphome/external_components/2851613f/esphome/components/lilygo_t5_47/display/__init__.py", line 45, in to_code config[CONF_LAMBDA], [(display.DisplayBufferRef, "it")], return_type=cg.void AttributeError: module 'esphome.components.display' has no attribute 'DisplayBufferRef'

Which now breaks compilations. :(

Thanks. Maybe there is a different (basic) mistake in my configuration?
So, this is my .yaml:

esphome:
  name: esphome-web-ce182c
  friendly_name: lilygo

esp32:
  board: esp32dev
  framework:
    type: arduino

api:
  encryption:
    key: "randomlyinserted"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

external_components:
  - source: github://ashald/esphome@lilygo-t5-47
    components:
      - lilygo_t5_47

time:
  - platform: homeassistant
    id: ntp

font:
  - id: large
    file: "fonts/calibri.ttf"
    size: 100

display:
  - platform: lilygo_t5_47
    id: eink
    update_interval: 10s
    full_update_every: 6
    lambda: |-
       it.printf(20, 20, id(large), id(ntp).now().strftime("%Y-%m-%dT%H:%M:%S").c_str());

Copied directly from esphome/feature-requests#1109 (comment)

My system is HA 2023.11.3 with OS 11.1 (generic-x86-64 on an SSD in an old Dell Wyse Thin Client)
ESPHome is 2023.11.4

No idea what's going wrong here.

Hi @idefxH

Using your updated component, do you have any idea why I would get the following issue when trying to use the touchscreen platform "lilygo_t5_47"?

touchscreen:

• platform: lilygo_t5_47
  id: lilygo_touchscreen
  interrupt_pin: GPIO13
  display: t5_display
  on_touch:
  • logger.log:
    format: Touch at (%d, %d)
    args: ["touch.x", "touch.y"]

ID 't5_display' of type lilygo_t5_47::LilygoT547Display doesn't inherit from display::Display. Please double check your ID is pointing to the correct value.

Many thanks in advance for the help! :)
