Hello Sharanu,
I was able to find an old example written in Visual C++ 6.0 that performed double buffered waveform generation on multiple channels with the 6711. The main purpose of this example is to give users an idea about programming the waveform generation on multiple channels using NI-DAQ C function calls and interleaving the data before performing the waveform generation. I hope that you are able to find this example useful.
Best of luck.
