[Alonso]

hi guys i need help for DAQmxBase Read and formula node. i need to acquire the data from the DAQmxBase Read and link them to the formula node. i cant get the formula node to accept the data and get my result.

In addition , there is a problem with a program that i have done to acquire biosignal from a Jennic Board (endpoint). This is because there is a error code 15 appearing on the PDA wants we press the stat button.

Hi Alonso,

Thank you for contacting National Instruments!  I believe that the reason that you're not getting the proper results for your Formula node is because you're actually passing out a 1D array from your DAQmx base Read vi.  If you only want to pass one value, I would recommend using the Index Array function to pull off one element at a time.

As for your error code 15 in LabVIEW PDA, since your problem is rather vague this KB might be useful:  DAQmx Base 1.0 Gives Error Code 15, What are Some Common Solutions?
