Psychtoolbox>Datapixx.{mex*} subfunction

status = Datapixx(‘GetDinStatus’);

Returns a struct containing the following digital input status information:
-“doutDinLoopback” is 1 if digital inputs are driven internally by digital
outputs, or 0 if digital inputs report real inputs from db-25 connector.
-“dataDirection” is a mask showing which of the 24 bits are driving their
outputs.
-“dataOutStrength” is the drive strength for the ports whose outputs have been
enabled by SetDinDataDirection.
-“debounce” is 1 if digital inputs are debounced for 30 milliseconds.
-“logRunning” is 1 if transition logging is currently active, or 0 if stopped.
-“bufferBaseAddress” is the acquisition data buffer base address within the
Datapixx.
-“bufferSize” is the number of bytes in the acquisition data buffer.
-“numBufferFrames” is the total number of samples which fit in the acquisition
data buffer.
-“currentWriteFrame” is the buffer frame which will be written by the next
acquired sample.
-“currentReadFrame” is the buffer frame which will be read by the next call to
ReadDinLog.
-“newLogFrames” = currentWriteFrame - currentReadFrame. This is the maximum
number of frames which can be read by the next call to ReadDinLog, without
causing an underflow.
-“numLogUnderflows” is the number of ReadDinLog underflows which have occurred
since SetDinLog. See ReadDinLog for details.
See DatapixxSimonGame, DatapixxDin*Demo files for examples.
