%   DatapixxToolbox
%   Version 0.9, Aug 2009
%
%   The DatapixxToolbox is a set of MATLAB/Octave functions interfacing to
%   the DATAPixx hardware toolbox from VPixx Technologies.
%
%   See http://www.vpixx.com/datasheets/ds_datapixx.pdf for more info.
%
%   DATAPixx features:
%
%       * Data acquisition and graphics system for the vision sciences
%       * Receives DVI input from laptop or PC 
%       * Transmits dual synchronized VGA outputs with 16-bit video DACs
%       * 16 channels of 16-bit analog inputs simultaneously sampled at up to
%         200 kHz per channel.
%       * 4 channels of 16-bit analog outputs simultaneously updated at up to
%         1 MHz per channel.
%       * Stereo audio inputs/outputs, sampled at up to 96 kHz.
%       * 24 TTL inputs with timetagged transitions.
%       * 24 TTL outputs
%       * All digital/analog/audio output transitions can be initiated
%         with microsecond-precision to video refresh
%       * All digital/analog/audio input acquisition can be correlated
%         with microsecond-precision to video refresh
%
%   The DatapixxToolbox implements basic functionality in a single Mex file,
%   and includes a set of demo M-Files in the DatapixxDemos folder.
%
%   For a complete list of available functions type "Datapixx" in the matlab
%   command window.
%
%   For an explanation of any particular Datapixx sub-function just add a
%   question mark after a command, eg: Datapixx SetDacSchedule?
%
%   LINUX: If you want to use these functions without the need to run
%   Matlab or Octave as root user (i.e., without need for root login or the
%   sudo command), please copy the file ...
%   Psychtoolbox/PsychHardware/DatapixxToolbox/60-vpixx-permissions.rules
%   ... into the folder /etc/udev/rules.d/ on your system. This one time copy will
%   require administrator privileges, but after that, any user should be able
%   to use the Datapixx devices or other VPixx devices without special permissions.
