++.TH I2CGETWIDE 8 "March 2016"
++.SH "NAME"
++i2cgetwide \- read from I2C chip registers of arbitrary data/address length
++
++.SH SYNOPSIS
++.B i2cgetwide
++.RB [ -f ]
++.RB [ -y ]
++.I i2cbus
++.I chip-address
++.I data-address-length
++.I data-address
++.I data-length
++.br
++.B i2cgetwide
++.B -V
++
++.SH DESCRIPTION
++i2cgetwide is a small helper program to read registers visible through the I2C
++bus. This should be used for registers whose addresses are greater than 1 byte
++and register value is greater than 1 byte.
++
++.SH OPTIONS
++.TP
++.B -V
++Display the version and exit.
++.TP
++.B -f
++Force access to the device even if it is already busy. By default, i2cgetwide
++will refuse to access a device which is already under the control of a
++kernel driver. Using this flag is dangerous, it can seriously confuse the
++kernel driver in question. It can also cause i2cgetwide to return an invalid
++value. So use at your own risk and only if you know what you're doing.
++.TP
++.B -y
++Disable interactive mode. By default, i2cgetwide 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. Use with caution.
++.PP
++There are five required options to i2cgetwide. \fIi2cbus\fR indicates the number
++or name of the I2C bus to be scanned. This number should correspond to one of
++the busses listed by \fIi2cdetect -l\fR. \fIchip-address\fR specifies the
++address of the chip on that bus, and is an integer between 0x03 and 0x77.
++.PP
++\fIdata-address-length\fR specifies the length of the address of the register
++on that chip.
++.PP
++\fIdata-length\fR specifies the length of the value of the register
++on that chip.
++.PP
++\fIdata-address\fR specifies the address on that chip to read from, and it is a
++list of length \fIdata-address-length\fR.
++
++.SH WARNING
++i2cgetwide can be extremely dangerous if used improperly. I2C and SMBus are designed
++in such a way that an SMBus read transaction can be seen as a write transaction by
++certain chips. This is particularly true if setting \fImode\fR to \fBcp\fP (write byte/read
++byte with PEC). Be extremely careful using this program.
++
++.SH SEE ALSO
++i2cdump(8), i2cset(8) i2cget(8)
++
++.SH AUTHOR
++Renga Aravamudhan
++
++This manual page was strongly inspired from those written by Jean Delvare
++for i2cget.
