All-in-one e-paper display ``Inkplate 6``, ``Inkplate 10`` and ``Inkplate 6 Plus``.

The Inkplate 6, 10 and 6 Plus are powerful, Wi-Fi enabled ESP32 based six-inch e-paper displays -
recycled from a Kindle e-reader. Its main feature is simplicity.

.. warning::

    When using the Inkplate epaper module, the GPIO pin numbers above *cannot be changed* as they are
    hardwired within the module/PCB.

.. warning::

    Inkplate module cannot perform partial update if 3 bit mode is on.
    It just ignores the function call in that case.

Inkplate 6 Plus Touchscreen
***************************

The Inkplate 6 Plus has a built in touchscreen supported by ESPHome. Note you need to enable pin 12 on the mcp23017 to enable the touchscreen
Below is a config example with touchscreen power switch:

.. code-block:: yaml

    switch:
      - platform: gpio
        name: 'Inkplate Touchscreen Enabled'
        restore_mode: ALWAYS_ON
        pin:
          mcp23xxx: mcp23017_hub
          number: 12
          inverted: true
          
    touchscreen:
      - platform: ektf2232
        interrupt_pin: GPIO36
        rts_pin:
          mcp23xxx: mcp23017_hub
          number: 10
        on_touch:
          - logger.log:
              format: "touch x=%d, y=%d"
              args: ['touch.x', 'touch.y']

Inkplate 6 Plus Backlight
***************************

The Inkplate 6 Plus has a built in backlight supported by ESPHome.
Below is a config example:

.. code-block:: yaml

    power_supply:
      - id: backlight_power
        keep_on_time: 0.2s
        enable_time: 0s
        pin:
          mcp23xxx: mcp23017_hub
          number: 11

    output:
      - platform: mcp47a1
        id: backlight_brightness_output
        power_supply: backlight_power

    light:
      - platform: monochromatic
        output: backlight_brightness_output
        id: backlight
        default_transition_length: 0.2s
        name: '${friendly_name} Backlight'

Inkplate 6 v2
***************************

The Inkplate 6 v2 has a slightly different configuration. The main difference is that it is using pca6416a instead of the mcp23017.
Below is a config example:

.. code-block:: yaml

    # Example minimal configuration entry
    pca6416a:
      - id: pca6416a_hub
        address: 0x20

    display:
    - platform: inkplate6
      id: inkplate_display
      greyscale: true
      partial_updating: false
      update_interval: never
      model: inkplate_6_v2

      ckv_pin: 32
      sph_pin: 33
      gmod_pin:
        pca6416a: pca6416a_hub
        number: 1
      gpio0_enable_pin:
        pca6416a: pca6416a_hub
        number: 8
      oe_pin:
        pca6416a: pca6416a_hub
        number: 0
      spv_pin:
        pca6416a: pca6416a_hub
        number: 2
      powerup_pin:
        pca6416a: pca6416a_hub
        number: 4
      wakeup_pin:
        pca6416a: pca6416a_hub
        number: 3
      vcom_pin:
        pca6416a: pca6416a_hub
        number: 5
