NAME

       iio_reg - do a low level read or write to SPI or I2C register

SYNOPSIS

       iio_reg [ options ] <device> <register> [<value>]

DESCRIPTION

       iio_reg  is  a  utility  for debugging local IIO devices.  It should not be used by normal
       users, and is normally used by driver developers  during  development,  or  by  end  users
       debugging  a  driver, or sending in a feature request.  It provides a mechanism to read or
       write SPI or I2C registers for IIO devices.  This can be useful when  troubleshooting  IIO
       devices, and understanding how the Linux IIO subsystem is managing the device.

       This IIO utility does not work across a network or USB context.

OPTIONS

       -h, --help
              Tells iio_reg to display some help, and then quit.

RETURN VALUE

       If the specified device is not found, a non-zero exit code is returned.
