:description: Instructions for setting up Inkplate E-Paper displays in ESPHome.
:image: inkplate6.jpg
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.
Configuration variables:
************************
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
- **model** (*Optional*, enum): Specify the model. Defaults to ``inkplate_6``.
- ``inkplate_6``
- ``inkplate_10``
- ``inkplate_6_plus``
- **greyscale** (*Optional*, boolean): Makes the screen display 3 bit colors. Defaults to ``false``
- **partial_updating** (*Optional*, boolean): Makes the screen update partially, which is faster, but leaves burnin. Defaults to ``false``
- **full_update_every** (*Optional*, int): When partial updating is enabled, forces a full screen update after chosen number of updates. Defaults to ``10``
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for rendering the content on the display.
See :ref:`display-engine` for more information.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to re-draw the screen. Defaults to ``5s``.

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 swtich:
.. code-block:: yaml
switch:
- platform: gpio
name: 'Inkplate Touchscreen Enabled'

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
