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
              command  used  is  the  one  believed  to be the safest for each
              address).  Not recommended. This  is  known  to  lock  SMBus  on
              various  write-only  chips  (most notably clock chips at address
              0x69).

       -V     Display the version and exit.

       -l     Output a list of installed busses.
