Hi all,
I'm doing high speed DAQ with PCIe-6251 board under win XP, I created a subVI to generate the data to be written into the board. I'm doing 8 channels DO with 64 samples (or more later). The output I want to achieve is like
As you can see, the frequency of a channel is half of the previous one.
So I created the following array:
The value of data changed with the channel. I don't consider it as the best solution, for it is more complex than I expected. But after I write them into the buffer, it works. And if I use 1 instead of 2, 4, 8 and so on, I won't see the wave from the DO channels except line 0; if I create a 1D array from 0 to 63, then there is an error telling that the sourse of the data does not match with the target.
So is it the only format of the data? Is there some others? Thank you.
Best wishes,
Bo
