Digital multiple input

[Ionut2008]

but not i nedd to analyze a signal from one  digital input?

think this is good? and do not know how to save data alarm

Hello lonut,

You still need to select a value for the channel input constant. Also, your split signals function only splits into one signal - you should drag it down to select two. 

I'm not sure what the audio output VI is supposed to do, given that you're just hooking up the data signal to the output of a a greater than/equal VI. 

For writing to file, see the example I linked to in my first post. 

Also, definitely check out that white paper I linked before. It should give you info on what each DAQmx VI is doing. http://www.ni.com/white-paper/5468/en

hello,do you know a relation between rotation and position of the body?and how to scale the signal read by AI?

Hello lonut,

The relationship between rotation and position is going to be dependant on how your system is setup, and is something you will need to calculate.

You can scale the signal that you're reading on the AI line using the mathematical functions within LabVIEW (such as multiple and divide). These functions can actually perform a mathematical operation on an entire array of data.
