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  inte-
       gers.  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 INFORMATION

       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 Comedi web site is located at http://www.comedi.org/comedi.
