-I2C Addresses
----------------
-I2C addresses are 7-bit values. However, most vendors who make LEGO compatible
-sensors provide an 8-bit address in their documentation.
-To use those addresses, you must shift them by 1 bit.
-For example, if the documented address is ``0xD2``, you can do
-``address = 0xD2 >> 1``.
-
-Advanced I2C Commands
----------------------
-Some rudimentary I2C devices do not require a register argument or even any
-data. You can achieve this behavior as shown in the examples below.

-The ``I2CDevice`` class methods call functions from the Linux SMBus driver.
-To find out which commands are called under the hood, check the
-`Pybricks source code`_.
-More details about using I2C without MicroPython can be found on
