I like these little computers. Beagleboard is the brand I ended up using. Full-fledged enough to compile its own programs. If you can do that on RP, that's worth the effort and extra space IMO, much less throwing files around and version mismatch problems update problems etc etc etc.
I'm trying to record audio using Audacity 2.0.5 installed from SlackBuilds. My system is 64-bit Slackware 14.1 and a sound card is Intel HD Audio. I didn't change my sound system to OSS. (Default sound system in Slackware 14.1 is ALSA, isn't it?) First, I set Internal Microphone slider in KMix... (2 Replies)
Hi,
I'm here again for newbie questions :)
I've installed Solaris 10 but audio don't work.I've a Realtek integrated peripheral,listed in Sun Hcl.The volume control is ok also.But nothing came from speakers.
I need to install unrar also,I've download it from here Freeware for Solaris with... (1 Reply)
comedi_calibrate(8) System Manager's Manual comedi_calibrate(8)NAME
comedi_calibrate - COMEDI calibration utility
SYNOPSIS
comedi_calibrate [-f /dev/comediN]
DESCRIPTION
comedi_calibrate is used to autocalibrate comedi devices. Some comedi devices have the ability to measure internal stable voltage refer-
ences and control gains and offsets using programmable DACs. On these devices, comedi_calibrate determines the proper values to feed into
the programmable calibration DACs. These calibration settings are then saved to a file, which can be fed to comedi_apply_calibration() and
related functions.
If comedi_calibrate finds an existing calibration file, it will not perform a new calibration by default. It will simply read its calibra-
tion information from the file. This behaviour may be overridden with the --calibrate option, to force a new calibration to be performed.
After obtaining the calibration information for the board, comedi_calibrate will then apply a calibration setting appropriate for the spec-
ified subdevice, channel, and range (see the --subdevice , --channel , and --range options below). See the comedilib documentation for
comedi_apply_calibration() for more information.
comedi_calibrate prints a lot of debugging information as it runs.
LIMITATIONS
comedi_calibrate only works on boards that it understands. For boards that are known to have autocalibration ability, but are not cur-
rently supported, comedi_calibrate will output basic debugging information that is useful for the author to add support for your device.
Please send this output to him.
EXAMPLES
comedi_calibrate --file /dev/comediN
If no default calibration for /dev/comediN already exists, perform a calibration and save results to default location.
comedi_calibrate --calibrate
Perform a calibration, using existing calibration (if it exists) as starting point.
comedi_calibrate --reset --calibrate
Perform a fresh calibration and save results to default location.
comedi_calibrate --no-calibrate --subdevice subd
--range range --save-file cal_file
Apply calibration for subdevice subd, range range, using the settings in the calibration file cal_file.
OPTIONS
comedi_calibrate recognizes the following options:
-a aref, --aref aref
Along with --channel, --range and --subdevice, this specifies which calibration you want comedi_calibrate leave applied to the
board. The default is 0.
--[no-]calibrate
Force calibration to be performed (or not). By default, comedi_calibrate will only perform a new calibration if no existing cali-
bration file is found (see --save-file).
-c channel,--channel channel
Along with --subdevice, --range and --aref, this specifies which calibration you want comedi_calibrate to leave applied to the
board. The default is 0.
--[no-]dump
Perform (or not) dump of various information about state of calibration prior to performing new calibration.
-f /dev/comediN,--file /dev/comediN
Perform calibration on device /dev/comediN.
--help Print help for options then exit.
-q, --quiet
Don't generate output to stdout.
-r range, --range range
Along with --channel, --subdevice and --aref, this specifies which calibration you want comedi_calibrate to leave applied to the
board. The default is 0.
--[no-]reset
Reset (or don't reset) calibration subdevice to a reasonable starting point before performing calibration. The default is
--no-reset. If --no-reset is used, the calibration routine will try to use an existing calibration (see --save-file) as a starting
point. This is useful if a single calibration pass is not sufficient, and you wish to perform another calibration pass starting
from the results of the previous pass.
--[no-]results
Perform (or not) dump of various information about state of calibration after performing new calibration.
-S file, --save-file file
Save calibration information to specified file, instead of default location. If the file already exists, comedi_calibrate will also
use its contents as a starting point for the calibration pass (see --no-reset).
-s subdevice, --subdevice subdevice
Along with --channel, --range and --aref, this specifies which calibration you want comedi_calibrate to leave applied to the board.
The default is 0.
-v, --verbose
Generate more verbose output to stdout, can be specified multiple times
