www.ti.com DLP LightCrafter Embedded Software Overview
1.3 DLP LightCrafter Embedded Software Overview
1.3.1 DM365 Software
The DLP LightCrafter module software is based on TI’s DVSDK platform running on the Digital Media
System-on-Chip DM365. The DVSDK platform is a collection of royalty-free software components built
upon Linux operating system and pre-tested by TI. The software components include Linux kernel, Linux
filesystem, Linux product support package (PSP), application framework (APIs), codec libraries (MPEG4,
H.264, MPEG2, G.711, JPEG), example programs, DSP Codegen, and CodeSourcery tool chain with IDE
for cross-compiling and debugging target systems.
Figure 1-5. DM365 DVSDK Software Platform
Out of the box, the DLP LightCrafter boots from the on-board NAND FLASH. The DM365 acts as the main
processor of the system and boots as an embedded Linux device. The Linux file system resides on the
NAND or micro-SD card. Thus, the DLP LightCrafter does not require an NFS mount nor a TFTP server to
run. The embedded Linux system utilizes Remote Network Drivers Interface Specification (RNDIS) to send
packets through USB. DLP LightCrafter has a default IP address of 192.168.1.100.
1.3.1.1 Serial Communication
DLP LightCrafter’s UART port serves as a console output of the embedded Linux device. The DM365
sends error messages through the UART and accepts root level commands. A 2.5-mm stereo plug to
female DB9 connector is needed to connect the DLP LightCrafter’s UART port to a PC. For PCs with only
USB ports, use a USB-to-serial RS232 adapter.
To view UART console messages, configure a terminal emulator with the following parameters:
• Baud: 115200
• Data Bits: 8
• Stop Bits: 1
• Parity: None
• Flow Control: None
1.3.2 FPGA Overview
The FPGA expands the functionality of the DLP 0.3-inch WVGA chipset to enable the features of DLP
LightCrafter. An important feature of DLP LightCrafter is the ability to display stored patterns at high frame
rates. The FPGA provides the timing and signal management to implement a four buffer rotation scheme,
which enables a stored pattern capability of 4x24=96 binary patterns. Additional capabilities include:
• An external trigger input, which allows an external device to trigger stored patterns; configurable for
polarity (positive or negative), delay, and duration (pulse width).
• An external trigger output, which provides the ability to synchronize an external camera with the
display of patterns; configurable for polarity (positive or negative), delay, and duration (pulse width).

DLP LightCrafter Embedded Software Overview www.ti.com
• A timing generator, which implements the internal auto trigger for continuously repeated pattern
display.
• Control for the illumination LEDs; generates LED strobe signals with configurable delay and duration to
set exposure; synchronized with the trigger.
• A video data source input selector (MUX); sends the video data to the DLPC300 parallel input. Inputs
are:
– Video from the TFP401A DVI receiver
– DM365 24-bit RGB (not bit identical with stored patterns)
– DM365 YUV4:2:2 video converted to RGB888 (bit identical with stored patterns).
• Timing and signal management for a "circular" frame buffer.
Please read the DLP LightCrafter FPGA Overview application note for more details. TI literature number
DLPA042 .Figure 1-6 shows the block diagram of the FPGA hardware.
Figure 1-6. DLP LightCrafter FPGA Block Diagram
1.3.3 MSP430 Overview and Shutdown Protection Modes
The MSP430 controls the power sequencing, initializes the DLPC300, and provides safety shutdown
protection modes for DLP LightCrafter. The MSP430 has three shutdown protection modes. The shutdown
modes require that both the system power and USB cable be disconnected before a reboot is allowed.
Each mode is displayed by blinking the Red LED (D3) on the driver board at different rates. Table 1-2
describes the protection modes.

DLPU006C–January 2012–Revised December 2013
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.

2. Turn on DLP LightCrafter using the On-Off switch. A new network using the RNDIS driver should
initialize.
• The network interface on Windows systems may take a couple minutes to initialize. Please read
Section 2.2.4 to speed up the initialization.
to speed up the initialization.
3. Open the DLP LightCrafter GUI.
4. Click the "Connect" button. See Figure 2-1.
• The GUI connects to the IP address in the "Current IP Address" textbox from the "Connections"
tab. Please read Section 2.2.5 steps 7 and 8 for more details.
• After connecting, the GUI displays DLP LightCrafter's firmware versions. Select the correct tab,
according to the Display Mode, to update the GUI's tab settings to match the EVM's settings.

2.2.1 Installing the RNDIS Driver on Windows XP
The first time DLP LightCrafter connects to Windows XP, a system pop-up window shows the new
"RNDIS/Ethernet Gadget" hardware device. Windows XP Service Pack 2 or greater includes the RNDIS
drivers, so these drivers should be found by the OS. Follow these steps to install the "RNDIS/Ethernet
Gadget" driver to enable USB communication with the EVM:
1. When the "Found New Hardware" dialog appears, as shown in Figure 2-3 and Figure 2-4, allow
Windows Update to search for the software.
2. Select “Install the software automatically (Recommended)” and click "Next." See Figure 2-4.
• The computer must have an active internet connection to download the driver.

2.2.2 Installing the RNDIS Driver on Windows 7
The first time DLP LightCrafter is connected on Windows 7 systems a pop-up window appears stating that
a new hardware device called a "RNDIS/Ethernet Gadget" was found. Follow these steps to install the
"RNDIS/Ethernet Gadget" driver to enable USB communication with the EVM:
1. The "Driver Software Installation" dialog should appear. Windows 7 will try to automatically download
the driver and fail. A message indicating that the “device driver software was not successfully installed"
