I cannot show the waveform n error message pop up saying tat:
Possible reason(s):
Attempted to read a sample beyond the final sample acquired. The acquisition has stopped, therefore the sample specified by the combination of position and offset will never be available.
Specify a position and offset which selects a sample up to, but not beyond, the final sample acquired. The final sample acquired can be determined by querying the total samples acquired after an acquisition has stopped.
Attempted to Read Sample: 1000
Property: RelativeTo Corresponding Value: Current Read Position
The reason you are getting that error is that you have a finite acquisition set up and you are reading more samples than the task thinks it is supposed to read. There are two inputs to the DAQmx Timing VI that determine 1) If the task is finite or continuous and 2) How many samples to read. Left unwired, this will result in a finite acquisition, reading 1000 samples. It looks like you want a continuous analog acquisition. There a bunch of great examples of this that install right into LabVIEW when NI-DAQmx is installed. They can be found in LabVIEW by going to Help>>Find Examples. Then navigate to Hardware Input and Output>>DAQmx>>Analog Measurement>>Voltage. I suggest looking at "Cont Acq&Graph Voltage-Int Clk.vi" That example should be what you are looking for. Hope this helps!
