.TH I2CDETECT 8 "July 2004"
|
|
.SH NAME
|
|
i2cdetect \- detect I2C chips
|
|
|
|
.SH SYNOPSIS
|
|
.B i2cdetect
|
|
.RI [ -f ]
|
|
.RI [ -q | -r ]
|
|
.I i2cbus
|
|
.br
|
|
.B i2cdetect
|
|
.I -l
|
|
|
|
.SH 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.
|
|
\fIi2cbus\fR indicates the number of the I2C bus to be scanned, and
|
|
should correspond to one of the busses listed by \fIi2cdetect -l\fR.
|
|
|
|
.SH WARNING
|
|
This program can confuse your I2C bus, cause data loss and worse!
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B "\-f"
|
|
Force scanning of non-regular addresses. Not recommended.
|
|
.TP
|
|
.B "\-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.
|
|
.TP
|
|
.B "\-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).
|
|
.TP
|
|
.B "\-l"
|
|
Output a list of installed busses.
