-I2C Scanner sample
-##################
-
-Overview
-********
-This sample sends I2C messages without any data (i.e. stop condition
-after sending just the address). If there is an ACK for the
-address, it prints the address as ``FOUND``.
-
-.. warning:: As  there  is  no  standard I2C detection command, this sample
-   uses arbitrary SMBus commands (namely SMBus quick write and SMBus
-   receive byte) to probe for devices.  This sample program can confuse
-   your I2C bus, cause data loss, and is known to corrupt
-   the Atmel AT24RF08 EEPROM found on many IBM Thinkpad laptops.
-   See also the `i2cdetect man page
-   <http://manpages.ubuntu.com/manpages/bionic/man8/i2cdetect.8.html>`_
