how to enable 2 or more analog input pin in arduino uno labview simultaneously for voltage analysis?

Hi Sammy_K,

I have tried your suggestions using the ReadPort vi but i'm still getting mixed voltage readings from 2 sensors in my circuit. For simplicity I have used a code similar to what mknix has posted above. Thanks!

If by "mixed voltage" you mean crosstalk (the signal from one line showing up on another), then you probably need to do some sort of sheilding for each of the sensor lines.  At least this is the suggestion that I got when I had this issue with an sbRIO.

I agree with Nathan_B. I would suggest you to double check your electronics and common ground connection. Try using a multi-meter to check input voltages. Good luck.

what does this error mean?

Hey mortenx,

You should create a new thread if your question is not related to the topic being discussed in this thread.

Thanks!
