Labview for touch panel

Getting Started with the LabVIEW

™

Touch Panel

Module

The LabVIEW Touch Panel Module extends the LabVIEW graphical development environment to

Touch Panel devices so you can create human-machine interface (HMI) applications for Touch Panel

devices running Windows CE or Windows XP Embedded. You can create custom touch panel displays

to communicate with National Instruments embedded real-time platforms, such as Compact FieldPoint,

CompactRIO, and Compact Vision System.

Installing Additional Tools

After installing the Touch Panel Module, you might need to install additional tools on the target depending

on the functionality you need.

NI-DAQmx Base

You can download the latest version of NI-DAQmx Base for use with Touch Panel devices from the

National Instruments Web site. After you complete the NI-DAQmx Base installation, you must copy

Refer to the NI-DAQmx Base Readme and the NI-DAQmx Base 3.x Getting Started Guide for more

information about NI-DAQmx Base.

NI TPC Service Support

The NI TPC Service is an Ethernet-based service that you can use to deploy, run, and debug Touch Panel

applications. Use the NI TPC Service instead of ActiveSync if you are using Ethernet and need to deploy

a Touch Panel application to multiple Touch Panel targets. If you are using third-party devices or your

NI Touch Panel device does not have the NI TPC Service installed, you must install the NI TPC Service

on the device before you can use the NI TPC Service. Most NI Touch Panel devices include the NI TPC

Service by default.

Windows CE Targets

3. For NI TPC devices, use the default installation location. Tap the <Enter> key to accept the default

installation location. For third-party devices, install the service in a non-volatile directory on the

device.

Third-Party XP Embedded Targets

You must install the LabVIEW Run-Time Engine on the Touch Panel target before you can install the

NI TPC Service. An installer for the LabVIEW Run-Time Engine is located on the LabVIEW DVD or

CD. Refer to the National Instruments Web site to download the latest version and other versions of the

LabVIEW Run-Time Engine.

After you install the LabVIEW Run-Time Engine on the Touch Panel target, install the NI TPC Service

from NI_TP_Service\NITPCService.msi, which is located in the same directory as the setup.exe

you do not need to complete the following steps. If you have an NI TPC-2006 device and you

Using ActiveSync/FTP

Complete the following steps to install or uninstall support for shared variables on a Touch Panel target

using ActiveSync/FTP.

Using the NI TPC Service

Complete the following steps to install or uninstall support for shared variables on a Touch Panel target

using the NI TPC Service.

1. In LabVIEW, right-click the Touch Panel target in the Project Explorer window and select

Install»Support for Shared Variables (ARM) from the shortcut menu.

2. For NI TPC devices, use the default installation location. For third-party devices, install the service

in a non-volatile directory on the device.

PNG Image Support (Windows CE)

If you are using third-party devices or your NI Touch Panel device does not support PNG images, you

must install support for PNG images on the device if the VI contains PNG images in the user interface.

using ActiveSync/FTP.

1. Connect the device to the host computer using ActiveSync/FTP.

2. Navigate to and run labview\PDA\Utilities\LVPNG\ARM\Setup.exe or

labview\PDA\Utilities\LVPNG\x86\Setup.exe, depending on which type of target you are

using.

3. For NI TPC devices, use the default installation location. For third-party devices, install the service

in a non-volatile directory on the device.

Using the NI TPC Service

NI-VISA Support (Windows CE)

You must install NI-VISA on the target to use VISA in Touch Panel applications. If you did not install

NI-VISA when you installed the Touch Panel Module, select Start»All Programs»National

Instruments»VISA and select Windows CE for ARM Driver Installation or Windows CE for x86

Driver Installation, depending on which type of target you are using.

x86 Target Support for Third Parties (Windows CE)

The Touch Panel Module installs support for ARM Touch Panel targets and Windows CE 5.0 x86 Touch

Panel targets. If you need support for x86 Touch Panel targets running Windows CE 4.2, install the

Windows CE Tutorial

Use this tutorial to learn how to congure a Touch Panel Windows CE device to use the NI TPC Service;

how to use the Touch Panel Project Wizard to create a project; and how to build, deploy, run, and debug

a Touch Panel application.

The VI in this tutorial simulates setting a temperature, displaying the current temperature in a graph and

on a thermometer, and indicating if the temperature is not in range.

Configuring the Windows CE Device to Use the NI TPC Service

Note If you want to use ActiveSync instead of the NI TPC Service, you must use a USB or

serial connection to connect the Touch Panel device to the host computer. If you use a serial

cable, connection time is longer.

2. Enable FTP on the Touch Panel device. Refer to the National Instruments Web site at ni.com/info

and enter the Info Code ex6pwq for the most recent information about conguring NI TPC devices
