Returns a struct containing the following digital output status information:
-“buttonSchedules” is 1 if DIN button presses cause automatic DOUT schedules.
-“backlightPulse” is 1 if LCD backlight LED enables are gated by DOUT15.
-“scheduleRunning” is 1 if digital output waveform playback schedule is
currently running, or 0 if stopped.
-“scheduleOnset” is the programmed delay in seconds between StartDoutSchedule
execution, and the first TTL output update.
-“scheduleRate” is the rate at which the generated waveform is sampled.
-“scheduleRateUnits” is the programmed units of scheduleRate:
1: samples per second
2: samples per video frame
3: seconds per sample
-“bufferBaseAddress” is the waveform data buffer base address within the
-“bufferSize” is the number of bytes in the waveform data buffer.
-“numBufferFrames” is the total number of samples which fit in the waveform data
buffer specified in SetDoutSchedule.
-“currentWriteFrame” is the buffer frame which will be written by the next
streaming call to WriteDoutBuffer.
-“currentReadFrame” is the current buffer frame being sent to the digital
-“freeBufferFrames” = numBufferFrames - (currentWriteFrame - currentReadFrame).
This is the maximum number of frames which can be written by the next call to
WriteDoutBuffer in streaming mode, without causing a streaming overflow.
-“maxScheduleFrames”, if non-0, is the value of currentReadFrame which will
automatically stop the schedule.
-“numStreamUnderflows” is the number of WriteDoutBuffer streaming underflows
which have occurred since SetDoutSchedule. See WriteDoutBuffer for details.
-“numStreamOverflows” is the number of WriteDoutBuffer streaming overflows which
have occurred since SetDoutSchedule. See WriteDoutBuffer for details.
