The documentation for this unknown device will tell you: 1. Whether this is possible; 2. If it is possible, how to do it.
So: have you studied the documentation for this device?
Have you looked at the manufacturer's website for support - examples, application notes, etc?

You obviously didn't pay attention to the clear instructions on how to post source to this forum:

You really need to pay close attention to the documentation if you want things to work properly!
