Operating the DLP LightCrafter

This chapter describes installing the Graphical User Interface (GUI), controlling the DLP LightCrafter

Module using the GUI, and upgrading the firmware on the EVM. All instructions relating to the GUI in this

document refer to the latest DLP LightCrafter GUI v5.0.

2.1 Installing the GUI

DLP LightCrafter includes a QT-based GUI to control the module through USB. QT is a Nokia cross-

platform application and user interface framework with open source and commercial licenses. To install

the DLP LightCrafter GUI, follow these steps.

1. Download the most recent version of the DLP LightCrafter Software Bundle from

http://www.ti.com/tool/dlplightcrafter.

• Linux users will also need to install the latest QT version 5 library. Available from http://qt-

project.org/downloads. After the QT library has been installed, the user must create a file in the

"etc/ld.so.conf.d" directory so that the GUI coorrectly accesses the QT library. Create a file called

"Qt5.conf" in the "etc/ld.so.conf.d" directory and enter the location of the QT5 library directory. For

example, "<QtInstall_dir>/5.1.1/gcc/lib". Verify the actual directory path of the "lib" directory in the

installed QT5 library. After the file has been saved, run "ldconfig" in the terminal.

2. Extract the files from the downloaded zip file.

3. Run the DLP LightCrafter Software Bundle installer.

• Linux users may need to right click on the installer file and set a property to "Allow executing file as

program" so the installer executes correctly.

• Linux and Mac installers may attempt to install the software bundle to the root directoy, which for

some users may not be accessible. Choosing a different installation directory, such as the user's

home or documents folder should allow the installation to run properly.

4. From the GUI directory of the installed software, double click on the LightCrafterGUI application to run

the GUI. By default the GUI is installed in one of the following directories:

• Windows XP & 7: "C:\Texas Instruments-DLP\DLPLCRSoftwareBundle-3.0\LightCrafterGUI-v5.0-

Windows"

• Linux: ".../Texas Instruments-DLP/DLPLCRSoftwareBundle-3.0/LightCrafterGUI-v5.0-Linux"

– Linux users may need to right click on the GUI executable file and set a property to "Allow

executing file as program" so the GUI operates correctly.

• Mac: ".../Texas Instruments-DLP/DLPLCRSoftwareBundle-3.0/LightCrafterGUI-v5.0-Mac"

2.2 Connecting to a PC

The DLP LightCrafter utilizes Remote Network Drivers Interface Specification (RNDIS) to send packets

through USB. Please read Section 2.2.1 or Section 2.2.2 to install the RNDIS drivers on Windows

systems. The drivers are already installed for Linux and Mac computers. Some Linux systems need to

have USB networking enabled.

After the RNDIS driver has been installed on the PC, please follow these steps to connect the DLP

LightCrafter. By default DLP LightCrafter's default IP address is "192.168.1.100," but this can be changed

to allow for multiple DLP LightCrafter's to connect to one computer. Please read Section 2.2.6 for more

details. To connect DLP LightCrafter to a PC, follow these steps:

1. Connect the DLP LightCrafter to the PC using a mini-USB cable.
