3 \fBcomedi_calibrate\fR - COMEDI calibration utility
5 \fBcomedi_calibrate\fR [-f /dev/comediN]
8 \fBcomedi_calibrate\fR is used to autocalibrate \fBcomedi\fR
9 devices. Some \fBcomedi\fR devices have the ability to
10 measure internal stable voltage references and control
11 gains and offsets using programmable DACs. On these devices,
12 \fBcomedi_calibrate\fR adjusts the programmable calibration
13 DACs so that the measured value of reference voltages fall
14 within acceptable limits. The calibration settings are
15 saved to a file which can be fed to the comedi_apply_calibration()
18 \fBComedi_calibrate\fR prints a lot of debugging information
23 \fBComedi_calibrate\fR only works on boards that it understands.
24 For boards that are known to have autocalibration ability,
25 but are not currently supported, \fBcomedi_calibrate\fR will
26 output basic debugging information that is useful for
27 the author to add support for your device. Please send this
33 \fBcomedi_calibrate\fR recognizes the following options:
35 \fB--[no-]calibrate\fR Perform calibration (or not).
37 \fB-f, --file /dev/comediN\fR perform calibration on device \fB/dev/comediN\fR
39 \fB--help\fR print help for options then exit
41 \fB-q, --quiet\fR don't generate output to stdout
43 \fB--[no-]reset\fR Reset (or don't reset) calibration subdevice to
44 a reasonable starting point before
45 performing calibration. The default is \fB--reset\fR. The
46 \fB--no-reset\fR option is useful if
48 pass is not sufficient, and you wish to perform another calibration
49 pass starting from the results of the previous pass.
51 \fB-s, --save-file <file path>\fR save calibration information to specified file,
52 instead of default location
54 \fB-v, --verbose\fR generate more verbose output to stdout, can be specified multiple times
