NAME

       comedi_config - COMEDI configuration utility

SYNOPSIS

       comedi_config [-vVq] /dev/comediN <driver> [<option1>[,<option2>...]]

DESCRIPTION

       comedi_config  is used to configure comedi drivers.  You must have comedi support compiled
       into your kernel or loaded as a separate module  in  order  to  use  this  utility.   Each
       control  and  measurement  device  is  associated  with  a  particular  comedi device file
       /dev/comediN, where N is 0,1,2,3, etc.  Comedi_config allows you to associate a particular
       driver  and device with a comedi device file, and also configure driver parameters for the
       particular device.

       Comedi_config can be used with optional parameters which are driver dependent.  Parameters
       are  specified  by  comma-delimited  list  of  integers.  The integers may be expressed as
       decimal, hexidecimal (starting with 0x)  or  octal  (stating  with  0).   In  addition,  a
       parameter  may  be  left  blank,  indicating  0.   PCI-based  devices typically require no
       parameters, although some allow you to specify the bus and slot of the card  to  configure
       as  the  first  two  parameters.   ISA-based  devices  typically  use the first and second
       parameters to indicate I/O base address and interrupt level.

       More information about the parameters required by individual drivers can be found  in  the
       comedi documentation, in the file drivers.txt.

OPTIONS

       comedi_config recognizes the following options:

       -q, --quiet    don't print output while running.

       -v, --verbose  print verbose output while running.

       -V, --version  print version number and exit.

       -r, --remove   remove previously configured driver.

       --read-buffer num
              set read buffer size to num kilobytes.  The default size is 64k.

       --write-buffer num
              set write buffer size to num kilobytes.  The default size is 64k.

       -i, --init-data, --init-data0 file
              upload initialization data (typically firmware) from file to board.

       --init-data1 file

       --init-data2 file

       --init-data3 file
              Some drivers require more than one file for initialization data.  Use these options
              to  specify  additional  initialization  data  files.   See   the   driver-specific
              documentation for further details.

CONFIGURATION FILE

       [This section has not been implemented yet.]

       A  list  of  device  configurations  can be put into the file /etc/comedi.conf.  This file
       takes the form

            <device> <driver> <param1>,<param2>,...

       These configurations will be read and performed when the  switch  -a  is  used.   This  is
       potentially useful when run from an initialization script.

EXAMPLES

       A  National Instruments PCI-MIO E series board can be configured to use /dev/comedi0 using
       the command:

            comedi_config /dev/comedi0 ni_pcimio

       A National Instruments AT-MIO E series board can be configured to use  /dev/comedi3  using
       the command:

            comedi_config /dev/comedi3 ni_atmio 0x220,3

       This tells the driver that the board is configured for I/O base 0x220 and IRQ 3.

       Additional  text  documentation can be found in /usr/share/doc/libcomedi-dev.  The current
       version of Comedi and Comedilib can be obtained from ftp://ftp.comedi.org/pub/comedi.  The
