NAME
       i2cdetect - detect I2C chips

SYNOPSIS
       i2cdetect [-y] [-a] [-q|-r] i2cbus
       i2cdetect -V
       i2cdetect -l


DESCRIPTION
       i2cdetect  is  a	 userspace  program to scan an I2C bus for devices. It
       outputs a table with the list of detected devices on the specified bus.
       i2cbus  indicates  the  number of the I2C bus to be scanned, and should
       correspond to one of the busses listed by i2cdetect -l.


WARNING
       This program can confuse your I2C bus, cause data loss and worse!

OPTIONS
       -y     Disable interactive mode. By default, i2cdetect will wait for  a
	      confirmation from the user before messing with the I2C bus. When
	      this flag is used, it will perform the operation directly.  This
	      is mainly meant to be used in scripts.

       -a     Force scanning of non-regular addresses. Not recommended.

       -q     Use  SMBus  "quick  write" commands for probing (by default, the
	      command used is the one believed	to  be	the  safest  for  each
	      address).	  Not  recommended. This is known to corrupt the Atmel
	      AT24RF08 EEPROM found on many IBM Thinkpad laptops.

       -r     Use SMBus "read byte" commands for probing (by default, the com‐
	      mand  used  is  the  one	believed  to  be  the  safest for each
	      address).	 Not recommended. This is known to lock SMBus on vari‐
	      ous write-only chips (most notably clock chips at address 0x69).

       -V     Display the version and exit.

       -l     Output a list of installed busses.
