Inkplate 6 ========== .. seo:: :description: Instructions for setting up Inkplate E-Paper displays in ESPHome. :image: Inkplate.jpg 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.

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 `): 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.
