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.
