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 section of the Comedilib manual.

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 INFORMATION

       Additional documentation may be found in the Configuration section of the Comedilib manual.
