Hey Folks:
I seem to be orbing around a solution to what I need, but always run into an error, that it seems nobody else is running into. I think I'm missing something.
Trying to do digital input with DAQ-mx on a PCIe-6535B along the following lines.
Data ----- X_BE56_X_78CD_X_FFE2_X .........
Strobe _____----_____-----_____----___ .........
I'm sending the strobe into PFI5 and the data are going into data ports 0 and 1.
I'm getting a errors along the lines of data timeouts etc along the lines of
DAQmxErrorCannotReadRelativeToRefTrigUntilDone (-200281)
I don't fully understand what DAQ-mx input modes are and I can't find a full write up that goes into depth on all the modes and how they work.
Also it seems that DAQ-mx is self contained. I can't find any write ups or examples on how to size buffers and transfter acquired data into arrays and files so I can actually do something with the data.
I'm using the canned examples, I've attached one, but there's very little explained here. Does anyone have any pointers?
Thanks
Andrew
