PXI 6713 - multiple waveforms triggered

Hello overyone I have a question:

 

Is it possible using the PCI 6713 and NI-DAQmx to upload several waveforms in the memory of the PXI-card and playback them by using a digital trigger. I was just able to do this once, which is unfortunately not enough...

 

So what I want is: Upload 2 (or more) waveforms, and then:

 

RisingEdge1 -> Play waveform1

RisingEdge2 -> Play waveform2

RisingEdge3 -> Play waveform1

RisingEdge4 -> Play waveform2 

....

 

and so on. Is this possible in principle? or is this something this card cannot do?

The C-example program: "ContGen-IntClk-AnlgStart" seems like a good start, and works, I just don't know how to continue now...

 

Thanks

Hi vienna2402,

 

The DAQ card has one FIFO in order to store the data which will be output using a D/A converter ( DAC buffer ). So in order to output several waves, you have to store these waves on the host ( PC) side and call them programmatically in your C code. I would suggest to use a counter within a loop. Depending on that value, the card should output the data onto the cards FIFO and finally output the signal.
