Psychtoolbox>Datapixx.{mex*} subfunction

doutNumBits = Datapixx(‘GetDoutNumBits’);

Returns number of digital output bits in the Datapixx. Currently the Datapixx
has 24 digital outputs. 16 of the digital outputs can be scheduled at up to 1
MHz for generation of precision digital waveforms. Digital outputs can also be
used for precise triggering of external stimulus and data acquisition systems
such as eye trackers or EEGs.
See DatapixxDout*Demo files for examples.
