6 comedi_config - COMEDI configuration utility

9 comedi_config [-vVq] /dev/comediN <driver> [<option1>[,<option2>...]]
10
12 comedi_config is used to configure comedi drivers. You must have
13 comedi support compiled into your kernel or loaded as a separate module
14 in order to use this utility. Each control and measurement device is
15 associated with a particular comedi device file /dev/comediN, where N
16 is 0,1,2,3, etc. Comedi_config allows you to associate a particular
17 driver and device with a comedi device file, and also configure driver
18 parameters for the particular device.
19 Comedi_config can be used with optional parameters which are driver
21 dependent. Parameters are specified by comma-delimited list of inte‐
22 gers. The integers may be expressed as decimal, hexidecimal (starting
23 with 0x) or octal (stating with 0). In addition, a parameter may be
24 left blank, indicating 0. PCI-based devices typically require no
25 parameters, although some allow you to specify the bus and slot of the
26 card to configure as the first two parameters. ISA-based devices typi‐
27 cally use the first and second parameters to indicate I/O base address
28 and interrupt level.
29 More information about the parameters required by individual drivers
31 can be found in the comedi documentation, in the file drivers.txt.

37 comedi_config recognizes the following options:
38 -q, --quiet don't print output while running.
40 -v, --verbose print verbose output while running.
42 -V, --version print version number and exit.
44 -r, --remove remove previously configured driver.
46 --read-buffer num
49 set read buffer size to num kilobytes. The default size is 64k.
50 --write-buffer num
53 set write buffer size to num kilobytes. The default size is
54 64k.
55 -i, --init-data, --init-data0 file
58 upload initialization data (typically firmware) from file to
59 board.
60 --init-data1 file
63 --init-data2 file
65 --init-data3 file
67 Some drivers require more than one file for initialization data.
68 Use these options to specify additional initialization data
69 files. See the driver-specific documentation for further
70 details.

76 A list of device configurations can be put into the file
78 /etc/comedi.conf. This file takes the form
79 <device> <driver> <param1>,<param2>,...
81 These configurations will be read and performed when the switch -a is
83 used. This is potentially useful when run from an initialization
84 script.

88 A National Instruments PCI-MIO E series board can be configured to use
89 /dev/comedi0 using the command:
90 comedi_config /dev/comedi0 ni_pcimio
92 A National Instruments AT-MIO E series board can be configured to use
94 /dev/comedi3 using the command:
95 comedi_config /dev/comedi3 ni_atmio 0x220,3
97 This tells the driver that the board is configured for I/O base 0x220
99 and IRQ 3.
