## 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)
