In labview, i'll need a simple program that allows you to control a digital pressure regulator and pump. I have a diaphragm pump which is controlled by it's DC motor. The input voltage controls the flow rate. I also have a digital pressure regulator which can read and interact with Labview to output the pressure waveforms. I need to setup a user interface and be able to control the pump input voltage(1-12V) and also see the pressure waveform change when the pump voltage/flowrate changes through the manual control. The pump controls would be setup through a DAQ or arduino and connect to the computer thru a USB-Servo controller(mini maestro 18-channel). The servo controller can amplify the pump above the 5V DAQ limit. The pressure regulator has a serial cable output that can connect to the USB with an adapter. You would just be setting up the servo controller to adjust the voltage on the pump and write a simple VI to show the pressure waveform when the voltage is adjusted.
