NAME

       comedi_config - COMEDI configuration utility

SYNOPSIS

       comedi_config [OPTION]... /dev/comediN driver [param1[,param2]...]
       comedi_config [OPTION]... -r /dev/comediN

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, hexadecimal (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,   and   in   the  Kernel  drivers
       ⟨http://www.comedi.org/doc/lowleveldrivers.html⟩   section   of   the   Comedilib   manual
       ⟨http://www.comedi.org/doc/index.html⟩.

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 (unconfigure) previously configured device.

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

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

       --subdevice-buffer num,size[,num,size]...
              Set  subdevice  num buffer size to size kilobytes.  More than one num,size pair may
              be specified, and the option may be used several times.

       -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    documentation    may    be    found    in    the    Configuration    section
