\fBcomedi_config\fR - COMEDI configuration utility

\fBcomedi_config\fR [-vVq] /dev/comediN <driver>

[<option1>[,<option2>...]]
9
\fBcomedi_config\fR is used to configure \fBcomedi\fR drivers.
10
You must have \fBcomedi\fR support compiled
11
into your kernel or loaded as a separate module in order
13
Each control and measurement device is associated with a
14
particular \fBcomedi\fR device file \fB/dev/comedi\fRN, where
16
\fBComedi_config\fR allows you to associate a particular
17
driver and device with a \fBcomedi\fR device file, and also
18
configure driver parameters for the particular device.
20
\fBComedi_config\fR can be used with optional
21
parameters which are driver dependent. Parameters are
22
specified by comma-delimited list of integers. The integers
23
may be expressed as decimal, hexidecimal (starting with 0x)
24
or octal (stating with 0). In addition, a parameter may be
25
left blank, indicating 0. PCI-based devices typically
26
require no parameters, although some allow you to specify
27
the bus and slot of the card to configure
28
as the first two parameters.
29
ISA-based devices typically use
30
the first and second parameters to indicate I/O base
31
address and interrupt level.
33
More information about the parameters required by individual
34
drivers can be found in the \fBcomedi\fR documentation, in
35
the file \fBdrivers.txt\fR.
41
\fBcomedi_config\fR recognizes the following options:
43
\fB-q, --quiet\fR don't print output while running.
45
\fB-v, --verbose\fR print verbose output while running.
47
\fB-V, --version\fR print version number and exit.
49
\fB-r, --remove\fR remove previously configured driver.
52
.BI "--read-buffer " "num"
53
set read buffer size to
55
kilobytes. The default size is 16k.
58
.BI "--write-buffer " "num"
59
set write buffer size to
61
kilobytes. The default size is 16k.
64
.SH CONFIGURATION FILE
66
[This section has not been implemented yet.]
68
A list of device configurations can be put into the file
69
\fB/etc/comedi.conf\fR. This file takes the form
71
<device> <driver> <param1>,<param2>,...
73
These configurations will be read and performed when the
74
switch \fB-a\fR is used. This is potentially useful when
75
run from an initialization script.
79
A National Instruments PCI-MIO E series board can be
80
configured to use /dev/comedi0 using the command:
82
comedi_config /dev/comedi0 ni_pcimio
84
A National Instruments AT-MIO E series board can be
85
configured to use /dev/comedi3 using the command:
87
comedi_config /dev/comedi3 ni_atmio 0x220,3
89
This tells the driver that the board is configured
90
for I/O base 0x220 and IRQ 3.
92
.SH ADDITIONAL INFORMATION
94
Additional text documentation can be found in /usr/doc/comedilib-0.7.11.
95
The current version of \fBComedi\fR and \fBComedilib\fR can be
96
obtained from ftp://ftp.comedi.org/pub/comedi. The Comedi web site
97
is located at http://www.comedi.org/comedi.
