.SH NAME
|
||||
\fBcomedi_config\fR - COMEDI configuration utility
|
||||
.SH SYNOPSIS
|
||||
\fB/usr/sbin/comedi_config\fR [-vVq] /dev/comediN <driver>
|
||||
<option1>[,<option2>...]
|
||||
.br
|
||||
.SH DESCRIPTION
|
||||
\fBcomedi_config\fR is a utility designed to configure
|
||||
control and measurement hardware associated with a particular
|
||||
\fBcomedi\fR device. You must have the \fBcomedi\fR module installed
|
||||
in the kernel to use this utility.
|
||||
|
||||
Each control and measurement card in your computer is associated
|
||||
with an individual comedi device; to a user, these appear as the
|
||||
files \fB/dev/comedi\fRN, with N being 0,1,2,3,etc. To configure
|
||||
\fBcomedi\fR to use a particular hardware driver for your card,
|
||||
you would use this utility with the device file, driver name, and
|
||||
other vital parameters (I/O base address, IRQ, etc.) on the
|
||||
command line.
|
||||
|
||||
As an example, the command line used to tell the comedi module that
|
||||
you want to access a National Instruments AT-MIO E series board as
|
||||
\fB/dev/comedi0\fR would be:
|
||||
|
||||
/usr/sbin/comedi_config /dev/comedi0 atmio-E 0x220,3
|
||||
|
||||
This tells the driver that the board is configured
|
||||
for I/O base 0x220 and IRQ 3. In general, I/O base is listed first
|
||||
and IRQ, if necessary, is listed second. Additional parameters
|
||||
vary, so see the information below for the particular driver.
|
||||
|
||||
Parameters can be expressed in either decimal or hexadecimal, with
|
||||
a 0x prefix.
|
||||
|
||||
|
||||
.SH OPTIONS
|
||||
|
||||
\fBcomedi_config\fR recognizes the following options:
|
||||
|
||||
\fB-a\fR obtain configuration information from the file
|
||||
/fB/etc/comedi.conf/fR.
|
||||
|
||||
\fB-q\fR don't print output while running.
|
||||
|
||||
\fB-v\fR print verbose output while running.
|
||||
|
||||
\fB-V\fR print version number and exit.
|
||||
|
||||
.SH HARDWARE DRIVERS
|
||||
|
||||
Additional information pertaining to each hardware driver is
|
||||
available in \fB/usr/doc/comedi-0.5.0\fR. Unless noted,
|
||||
the names below are the same as the driver names given on
|
||||
the command line.
|
||||
|
||||
\fB8255\fR Generic 8255 support
|

.br
|

<I/O base>

|

\fBdas08\fR - Keithley DAS08 and compatibles

\fBdt2811\fR - Data Translation DT2811
|

.br
|

<I/O base>
|
||||
.br
|
||||
Interrupts are not used with this board.

\fBdt2814\fR - Data Translation DT2814
|
||||
.br
|
||||
<I/O base>,<IRQ>
|
||||
.br
|

Set IRQ to -1 to probe for IRQ.

\fBdt2817\fR - Data Translation DT2817
|
||||
.br
|
||||
<I/O base>

<voltage range, analog input>,
|
||||
<voltage range, analog output 0>,
|
||||
<voltage range, analog output 1>.
|
||||
.br
|
||||
Valid values for analog reference are 0=single ended,
|
||||
1=differential.
|
||||
Valid values for encoding are
|
||||
[0=straight or offset binary, 1=two's complement].
|
||||
Valid values for voltage range are
|
||||
0=(-10,10), 1=(0,10), 2=(-5,+5), 3=(0,5),
|
||||
4=(-2.5,2.5).
|
||||
Options must agree with how your board is
|
||||
configured.
|
||||
.br
|
||||
The driver recognizes the following names:
|
||||
\fBdt2821\fR,
|
||||
\fBdt2823\fR,
|
||||
\fBdt2824-pgh\fR,
|
||||
\fBdt2824-pgl\fR,
|
||||
\fBdt2825\fR,
|
||||
\fBdt2827\fR,
|
||||
\fBdt2828\fR.
|
||||
Use the name that best represents your board.
|
||||
|
||||
\fBatmio-E\fR - National Instruments AT-MIO E series
|
||||
.br
|
||||
<I/O base>,<IRQ>
|
||||
.br
|
||||
This driver automatically detects which board is installed
|
||||
in your computer. The E-series boards are plug-and-play, so use
|
||||
\fBisapnptools\fR to tell the board which I/O port to use before
|
||||
running \fBcomedi_config\fR. In a random fit of stupidity, the
|
||||
E-series boards ignore the IRQ which PnP assigns to it.
|
||||
|
||||
\fBparport\fR - Standard PC parallel port digital I/O
|
||||
.br
|
||||
<I/O base>
|
||||
.br
|
||||
This driver does not work with the new parallel port sharing
|
||||
capabilities of Linux.

\fBpcl711\fR - PC-LabCard PCL-711, 711B, ACL-8112
|

Use the driver name \fBpcl711b\fR to configure for a 711B board.

.SH CONFIGURATION FILE
|
||||
|
||||
[This section has not been implemented yet.]
|
||||
|
||||
A list of device configurations can be put into the file
|
||||
\fB/etc/comedi.conf\fR. This file takes the form
|
||||
|
||||
<device> <driver> <param1>,<param2>,...
|
||||
|
||||
These configurations will be read and performed when the
|
||||
switch \fB-a\fR is used. This is potentially useful when
|
||||
run from an initialization script.
