comedi_config - COMEDI configuration utility
comedi_config [-vVq] /dev/comediN <driver> [<option1>[,<option2>...]]
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.
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.
set read buffer size to num kilobytes. The default size is 64k.
set write buffer size to num kilobytes. The default size is
-i, --init-data, --init-data0 file
upload initialization data (typically firmware) from file to
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
[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
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.
