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 16k.
set write buffer size to num kilobytes. The default size is
[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.
