VEAA-X-3 sample

##########################

Overview

********

A sensor sample that demonstrates how to use a VEAA-X-3 device.

Building and Running

********************

This sample sets the valve setpoint then reads the actual pressure.

This is done continuously. When the maximum supported pressure is reached the setpoint is reset to

the valve's minimum supported pressure value.
