NAME

comedi_config - COMEDI configuration utility

SYNOPSIS

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

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/comedi N, 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 .
