The National Instruments Getting Started with NI-DAQmx Series is aimed at helping you learn NI-DAQmx programming fundamentals. Through video

and text tutorials, this series will take you from verifying your device's operation in Measurement & Automation Explorer (MAX) to programming data

acquisition applications using LabVIEW. It is intended for both the beginner who wants to learn how to use the DAQ Assistant, as well as the

experienced user who wishes to take advantage of advanced NI-DAQmx functionality.

Overview

This tutorial explains how to use the DAQ Assistant to quickly develop and deploy a Visual Studio application that uses data acquisition and Measurement Studio. The DAQ Assistant is an

easy-to-use graphical interface for configuring measurement tasks and channels and for customizing timing, triggering, and scales without programming. Using the DAQ Assistant, you can

configure a measurement task for all of your data acquisition applications and then generate code to configure and use the task in your application program.

Before You Begin

To use this tutorial, you must have the following software and hardware installed on your system:

Visual Studio 2005/2008

Measurement Studio 8.0.1 or later (Professional or Enterprise package)

NI-DAQmx 8.1 or later 

 A DAQ device that is supported by NI-DAQmx. Refer to the file for a list of devices supported by NI-DAQmx. You may also create a simulated device in Measurement &NI-DAQ Readme

 Automation Explorer (MAX) in place of an actual data acquisition device.

Refer to the and the device documentation for information about installing and configuring the software and hardware.DAQ Quick Start Guide
