Potentiometer motion control

[men5ajh]

Hi,

I need to develop a simple program that will be able to alter the angular positions of two 2500 series potentiometers, seperately, which will in turn affect the motion of two links, by controlling the voltage. There also needs to be a 2D display of the movement of the links in an xy plane. I have only very basic knowledge of labview and I am unsure of how to start writing this program.

Thanks,

Al

Hi Al,

I would probably suggest starting by looking over some example code and tutorials.

1. This Video Tutorial is a getting started guide to analog outputs that should be able to start you off with that part of your code.

2.  There is also an example for analog output that I think is similar to what you want but only on one channel.  To launch the example finder goto help>>example finder in labview and then in the folders in the example finder go to 

hardware input and output>>DAQmx>>analog generation>> Gen Mult Volt Updates-SW Timed.vi.

3. For the xy graphs and other information you may need the LabVIEW help is very good and will also link to example code where it exists.  Particularly if you load the contents of the help and go to labview fundamentals>>graphs and charts.

I hope this gets you started.  Do ask again if you have any further questions and most of all enjoy!
