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).

## Thread-safe I2C with I2C Manager
|
||||
|
||||
LVGL can use I2C to read from a touch sensor or write to a display, possibly
|
||||
many times a second. Meanwhile, other tasks may also want to read from i2c
|
||||
devices on the same bus. I2C using the ESP-IDF is not thread-safe.
|
||||
|
||||
I2C Manager (`i2c_manager`) is a component that will let code in multiple threads
|
||||
talk to devices on the I2C ports without getting in each other's way. These drivers
|
||||
use a built-in copy of I2C Manager to talk to the I2C port, but you can also use
|
||||
the I2C Manager component itself and have others play nice with LVGL and vice-versa.
|
||||
[Click here](i2c_manager/README.md) for details.
|
||||
|
||||
|
||||
## Backlight control
|
||||
|
||||
Control of LCD's backlight is provided by separate module that is independent from the display driver.
|
||||
Configuration of the backlight controller can be found in menuconfig `LVGL ESP Drivers -> LVGL TFT Display controller`.
|
||||
|
||||
There are three modes of operation:
|
||||
1. Off - No backlight control
|
||||
2. Switch - Allows ON/OFF control
|
||||
3. PWM - Allows brightness control (by Pulse-Width-Modulated signal)
