NAME¶
eegdev-open-options - Device configuration format specification
DESCRIPTION¶
Syntax of the configuration string¶
The device configuration string should follow the syntax:
device[[|option1|value1]...[|optionN|valueN]]
If the specified device does not support a certain pair of option|value, this
will be silently ignored by the opening function.
device should be the
name of a eegdev plugin or
any. In the later case, it will try to open
one of the devices supported by the installed plugins.
Syntax of the configuration files¶
The configuration files are made of statements (at most one per line) following
this syntax (whitespace are ignored):
option = value
Comments are preceded by the '#' character:
# comment line 1
# comment line 2
option = value #comment2
FILES¶
- /etc/eegdev/eegdev.conf
- Shared configuration file.
- /etc/eegdev/<plugin>.conf
- Configuration file loaded when the plugin <plugin> is used.
The settings specified here overrides the settings in the shared
configuration file.

notch filter at 60Hz without lowpass or highpass sampling at 512Hz (default
sampling rate):
gtec|notch|60|lowpass|none|highpass|none|deviceid|any+any
Any supported type of device but should have the serial number UB-2009.10.06 if
it is a gTec system:
any|deviceid|UB-2009.10.06
