MCC USB-1808 Waveform Current point not updated

[sergeys21]

Waveform Generator Current point (WaveGenCurrentPoint) is not updated and stays at max when the waveform generator is in one-shot mode (WaveGenContinuous=0). It does work in the Waveform Generator continuous mode (WaveGenContinuous=1). Tested on MCC USB-1808.

I have reproduced this problem on both Windows and Linux. The value of the current point in the scan is read here in Windows:

measComp/measCompApp/src/drvMultiFunction.cpp

Line 2674 in c317107

status = cbGetIOStatus(boardNum_, &aoStatus, &aoCount, &aoIndex, AOFUNCTION);

and here in Linux:

measComp/measCompApp/src/drvMultiFunction.cpp

Line 2678 in c317107

status = ulAOutScanStatus(daqDeviceHandle_, &scanStatus, &xferStatus);

This code is independent of whether the scan is done in One-shot, or Continuous mode. So clearly the aoIndex is not being returned correctly by the underlying Measurement Computing driver, or by the device itself in One-shot mode.

I don't think there is anything we can do to fix the problem.
