All-in-one e-paper display ``Inkplate 6``
Inkplate 6 is a powerful, Wi-Fi enabled ESP32 based six-inch e-paper display 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.
- **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``.
- **pages** (*Optional*, list): Show pages instead of a single lambda. See :ref:`display-pages`.
- **ckv_pin** (**Required**, :ref:`config-pin`): The CKV pin for the Inkplate display.
- **gmod_pin** (**Required**, :ref:`config-pin`): The GMOD pin for the Inkplate display.
- **gpio0_enable_pin** (**Required**, :ref:`config-pin`): The GPIO0 Enable pin for the Inkplate display.
- **oe_pin** (**Required**, :ref:`config-pin`): The OE pin for the Inkplate display.
- **powerup_pin** (**Required**, :ref:`config-pin`): The Powerup pin for the Inkplate display.
- **sph_pin** (**Required**, :ref:`config-pin`): The SPH pin for the Inkplate display.
- **spv_pin** (**Required**, :ref:`config-pin`): The SPV pin for the Inkplate display.
- **vcom_pin** (**Required**, :ref:`config-pin`): The VCOM pin for the Inkplate display.
- **cl_pin** (*Optional*, :ref:`config-pin`): The CL pin for the Inkplate display.
Defaults to GPIO0.
- **le_pin** (*Optional*, :ref:`config-pin`): The LE pin for the Inkplate display.
Defaults to GPIO2.
- **display_data_0_pin** (*Optional*, :ref:`config-pin`): The Data 0 pin for the Inkplate display.
Defaults to GPIO4.
- **display_data_1_pin** (*Optional*, :ref:`config-pin`): The Data 1 pin for the Inkplate display.
Defaults to GPIO5.
- **display_data_2_pin** (*Optional*, :ref:`config-pin`): The Data 2 pin for the Inkplate display.
Defaults to GPIO18.
- **display_data_3_pin** (*Optional*, :ref:`config-pin`): The Data 3 pin for the Inkplate display.
Defaults to GPIO19.
- **display_data_4_pin** (*Optional*, :ref:`config-pin`): The Data 4 pin for the Inkplate display.
Defaults to GPIO23.
- **display_data_5_pin** (*Optional*, :ref:`config-pin`): The Data 5 pin for the Inkplate display.
Defaults to GPIO25.
- **display_data_6_pin** (*Optional*, :ref:`config-pin`): The Data 6 pin for the Inkplate display.
Defaults to GPIO26.
- **display_data_7_pin** (*Optional*, :ref:`config-pin`): The Data 7 pin for the Inkplate display.
Defaults to GPIO27.
