Jean Delvare 783c6a0ed6 Adapt probing method to address. Should prevent any kind of
EEPROM corruption. Previous method (quick writes for every
        address) can be forced with -q. Read bytes can be forced with -r.

.TH I2CDETECT 8 "March 2004"
.SH NAME
i2cdetect \- detect I\u2\dC 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 I\u2\dC bus for devices. It
outputs a table with the list of detected devices on the specified bus.
\fIi2cbus\fR indicates the number of the I\u2\dC bus to be scanned, and
should correspond to one of the busses listed by \fIi2cdetect -l\fR.
.SH WARNING
This program can confuse your I\u2\dC 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.
