## 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.
