# Display and touchpad drivers for ESP32 using LVGL

For a ready to use ESP32 project take look at the [lv_port_esp32](https://github.com/lvgl/lv_port_esp32) repository.

- [Supported indev controllers](#supported-indev-controllers)
- [Support for predefined development kits](#support-for-predefined-development-kits)

**NOTE:** You need to set the display horizontal and vertical size, color depth and
swap of RGB565 color on the LVGL configuration menuconfig (it's not handled automatically).

Please note that EPDiy supported epapers include also the Lilygo EPD47 that comes with it's own PCB and ESP32 WROVER. Is possible also to build your own EPDiy PCB, please find the [project KiCad source files, schematics, and documentation here](https://github.com/vroland/epdiy/tree/master/hardware/epaper-breakout). 
To use an EPDiy supported epaper you need to add it [as a component using git submodules](https://github.com/martinberlin/lv_port_esp32-epaper/tree/master/components) and also update the CMakeLists of lvgl component to [REQUIRE that library](https://github.com/martinberlin/lv_port_esp32-epaper/wiki).

    git submodule add https://github.com/martinberlin/epdiy-rotation.git components/epd_driver

## Supported indev controllers

- XPT2046
- FT3236
- other FT6X36 or the FT6206 controllers should work as well (not tested)
- STMPE610
- FT81x (Single, Dual, and Quad SPI)
- L58 touch component hook (Used in Lilygo EPD47 parallel with EPDiy driver)

If your display or input device (touch) controller is not supported consider contributing to this repo by
adding support to it! [Contribute controller support](CONTRIBUTE_CONTROLLER_SUPPORT.md)

## Support for predefined development kits

You can also use the predefined kits, which selects the correct display controllers on the kit,
and sets the gpio numbers for the interface.
