The MSP430 monitors the light engine's thermistor to shutdown the EVM if excessive heat is measured on
the green LED. Passively cooled systems (no extra heat sinks or fans) have a thermal limit resulting in
LED currents under 633 mA. Actively cooled systems (extra heat sink and fan) have a thermal limit
resulting in LED currents under 1.5 A. See Table 2-1 for the corresponding LED current software settings.

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 pretested 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 uses 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.

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 4 × 24 = 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)

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.
Table 1-2. DLP LightCrafter Protection Shutdown Modes
Shutdown Mode Description
System voltage less than 3.8 V or greater than 5.2 V

Chapter 2
DLPU006E – January 2012 – Revised November 2014
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 crossplatform 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
www.ti.com/tool/dlplightcrafter.
• Linux users also need to install the latest QT version 5 library. Available from http://qtproject.org/downloads. After the QT library is 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, "/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 directory, 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 and Windows 7: "C:\Texas Instruments-DLP\DLPLCRSoftwareBundle3.0\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 uses remote network drivers interface specification (RNDIS) to send packets
through USB. 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, 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. 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.

Setting the LED Current
The DLP LightCrafter uses current drivers to individually control the current through each LED using an
integer current value. The LED current is computed as follows:
LED Current (mA) = 1.8 × (LED Current Value) + 140
(1)
When at room temperature, the maximum value allowed is dependent on the cooling system of the DLP
LightCrafter. The passively cooled systems of the DLP LightCrafter (no extra heat sinks or fans) have a
thermal limit resulting in LED currents under 633 mA. DLP LightCrafter actively-cooled systems (extra heat
sink and fan) have a thermal limit resulting in LED currents under 1.5 A. Table 2-1 summarizes these
constraints. Figure 2-26 shows the "LED Current" settings in the GUI.

Creating Pattern Sequences
The DLP LightCrafter can perform external and internal pattern sequences. External sequences use
streaming patterns from the mini-HDMI port. Internal sequences use preloaded patterns and can be stored
on the LightCrafter with solutions for reuse. The following sections describe how to set up pattern
sequences on DLP LightCrafter.
2.8.1 Internal Stored Pattern Sequences
To create an internal pattern sequence follow these steps:
1. Set the display mode as "Stored Pattern Sequence".
2. Select the "Stored Pattern Sequence", then the "Sequence Settings" tab as shown in Figure 2-36.
Figure 2-36. DLP LightCrafter GUI Sequence Settings Tab in Stored Pattern Sequence Tab
3. Set Pattern settings by updating the following parameters inside the Pattern Setting box:
• Bit depth: bit depth of the image. Allowed values are from 1 to 8.
• Pattern count: amount of patterns to display in sequence. Allowed values 1 to 96 divided by the bit
depth. For example, if the bit depth is 8, the maximum amount of patterns is 96 / 8 = 12. If the bit
depth is 1, the maximum amount of patterns is 96/1 = 96.
• Pattern type
– Normal: display the pattern sequence. Available for all bit depths.
– Inverted: display the pattern sequence with each pattern followed by its inverted pattern.
Available for pattern sequences with bit depth equal to 1.
– HW pattern: display a pattern sequence created from hardwired (HW) patterns. See
Section 2.8.1.1 for more details.
• Trigger type: selects how the patterns are triggered.
– Auto: patterns displayed after end of trigger period.
– Command: patterns displayed when the Next button is pressed.
– External (positive): patterns displayed after an external active-high trigger signal.
– External (negative): patterns display after an external active-low trigger signal.

LED select: selects which color LED is active (red, green, or blue). See Section 2.8.1.2 for details
about using the Multiple setting.
Trigger delay: number of microseconds delay after trigger is received and pattern is displayed. See
Figure 2-37.
Exposure time: number of microseconds the pattern is displayed. Input 0 to display the pattern
through the whole trigger period. See Figure 2-37.
Trigger period: number of microseconds delay between two consecutive patterns. See Figure 2-37.

4. Click the Set button as shown in Figure 2-38.
• If the exposure or trigger period values are less than the minimum allowed, DLP LightCrafter
automatically sets the minimum values.
Figure 2-38. DLP LightCrafter GUI Pattern Sequence Settings Set Button
NOTE:
Changing the bit-depth, exposure, or pattern count requires that all the images need to be
uploaded again. Uploading all images is necessary since the pattern arrangement in the
frame memory buffer depends on these settings.
5. Click the Browse button to select the number of bitmap patterns matching the bit depth and number
previously set. See Figure 2-39 and Figure 2-40.
• The pattern number should be set to 0.
• The patterns must be a BMP file with a resolution of 608 × 684.
• The pattern file names should have their corresponding pattern numbers within the name (that is
00_PAT, 01_PAT, 02_PAT, and so forth)
– Each file should have the same number of digits for the pattern number
• Correct: 00_PAT, 01_PAT, 02_PAT, ... , 10_PAT, and so forth
• Wrong: 0_PAT, 1_PAT, 2_PAT, ... , 10_PAT, and so forth
• Click the pattern number drop down list to view the pattern in the GUI. This selected pattern can
then be displayed on the EVM by clicking Display This button.

Hardwired Pattern Sequences
The DLPC300 can generate a set of 15 vertical 1-bit monochrome patterns with its internal pattern
generator. These patterns are called hardwired patterns in the DLP LightCrafter GUI. Up to 32 of these
vertical patterns can be arranged in any order with or without inversion. The inversion of a pattern
converts the black regions to white and the white regions to black. For a description of the available
patterns, see Table 2-64 from the DLPC300 Programmer’s Guide, DLPU004. Pattern numbers 0 through
10 form a set of gray-coded patterns. Pattern numbers 11 through 14 can be used for auto-focus.
The extended pattern sequence mode follows the same steps as those listed in Section 2.8.1 for regular
internal stored pattern sequences except for selecting the images. Rather than clicking the Browse button,
select the desired HW Pattern from the dropdown list. See Figure 2-43.

2.8.1.2
Multiple Bit-Depth and Multiple Color Pattern Sequences
With the latest FPGA Firmware (version 2.6.43) and DM365 software (version 4 or above), the DLP
LightCrafter can run internal pattern sequences that use multiple bit depths and multiple colors (MBMC).
To create an MBMC pattern sequence, follow these steps:
1. Submit MBMC pattern sequence requests on TI's E2E forum in the DLP LightCrafter Development
Platform subsection (http://e2e.ti.com/) by creating a post titled "MBMC Request" and provide the
following information:
• Pattern exposure time (250 µs < PExT ≤ 20000 µs).
– This parameter influences the maximum bit-depth possible in the sequence for each pattern.
For example, if the exposure time is 1000 µs then it is only possible to have 1-bit or 2-bit depth
patterns. On the other hand, an exposure time ≥ 8333 µs supports patterns of all bit-depths
from 1 to 8. See Table 4-3 to find the minimum exposure time for each pattern’s bit-depth.
• Patterns Sequence Information as shown in Table 2-3.
– Patterns must be listed in the order to be displayed.
– Depending on the order of patterns with different bit-depths it is possible that there will be
unused bit-planes that still count towards the maximum 96 bit-planes. The system does not
allow split multiple bit-depth patterns across the 24-bit frame buffer boundaries. For example, in
the first row of Table 2-3, there are five, 5bpp patterns. This would translate to 5 × 5 = 25
individual bit planes, but each frame buffer can only accommodate 24 individual binary frames.
Therefore, in a pattern sequence of five 5-bit patterns, 20 reside in the first frame buffer, while
the last 5-bit plans reside in the next frame buffer. The 5bpp × 5 pattern set actually consumes
29 individual bit planes of the frame buffer:
• 5bpp × 4 patterns + 4 unused patterns = 24 patterns (from the first frame buffer)
• 5bpp × 1 pattern = 5 patterns (from the second frame buffer)
• Results in 24 + 5 = 29 individual binary patterns.

2.8.3 Extended Pattern Sequences
In addition to the high-speed internal stored pattern sequences, DLP LightCrafter can run extended
pattern sequences that allows more than 96 patterns and exposure times up to 5 s. (1) There are some
constraints to the extended pattern sequence mode:
• Sequences with more than 96 patterns are stored in the DDR DRAM 128MB memory connected to the
DM365 chip. So the maximum number of patterns allowed in this mode depend on free RAM space
after loading DM365 Linux Kernel and Root file system in the DDR memory. With the official
unmodified DM365 firmware build, the maximum number of patterns allowed in extended pattern
sequence mode is:
– Approximately 1000 1-bit per pixel patterns
– Approximately 125 8-bit per pixel patterns
• Longer exposures than 20 ms:
– Maximum exposure of 5 s for 8-bit per pixel patterns
– Maximum exposure of 2 s for 1-bit per pixel patterns
• Exposure times longer than 20 ms have to be multiples of 20 ms (for example, 20 ms, 40 ms, 60 ms,
and so forth).

Multiple bit and multiple color pattern sequences are not enabled in extended pattern sequence mode.

Pattern Sequences
This chapter describes the pattern sequences supported by the DLP LightCrafter Module
4.1
Pattern Sequence Background
The DLPC300 device takes as input 16-, 18-, or 24-bit RGB data at up to 60-Hz frame rate. This frame
rate is composed of three colors (red, green, and blue) with each color equally divided in the 60-Hz frame
rate. Thus, each color has a 5.55-ms time slot allocated. Because each color has 5-, 6-, or 8-bit depth,
each color time slot is further divided into bit-planes. A bit-plane is just one-bit representation of all the
pixels in the image. A 24-bit image is decomposed into its bit planes in Figure 4-1.
Figure 4-1. Relationship Between Bit Planes and 24-Bit RGB Images
The length of each bit-plane in the time slot is weighted by the corresponding power of 2 of its binary
representation. This provides a binary pulse-width modulation of the image. For example, a 24-bit RGB
input has three colors with 8-bit depth each. Each color time slot is divided into eight bit-planes, with the
sum of all bit planes in the time slot equal to 256. Figure 4-2 shows this partition of bits in a frame.
Figure 4-2. Relationship Between Bit Partition and Time
Therefore, a single video frame is composed of a series of bit planes. Because the DMD mirrors can be
either on or off, an image is created by turning on the mirrors corresponding to the bit set in a bit plane.
With the binary pulse-width modulation, the intensity level of the color is reproduced by controlling the
amount of time the mirror is on. For a 24-bit RGB frame image inputted to the DLPC300, the DLPC300
creates 24 bit planes, stores them on the mDDR, and sends them to the DLP3000 DMD, one bit plane at
a time. Depending on the bit weight of the bit plane, the DLPC300 device controls the time this bit plane is
exposed to light, controlling the intensity of the bit plane. To improve image quality in video frames, the bit
planes, time slots, and color frames are intertwined and interleaved with spatial-temporal algorithms by the
DLPC300 device.

External Patterns
www.ti.com
For other applications where this image enhancement is not desired, the video processing algorithms can
be bypassed and replaced with a specific set of bit planes. The bit depth of the pattern is then allocated
into the corresponding time slots. Furthermore, an output trigger signal is also synchronized with these
time slots to indicate when the image is displayed. For structured light applications, this mechanism
provides the capability to display a set of patterns and signal a camera to capture these patterns overlaid
on an object.
4.2
External Patterns
Using the mechanism described in the previous section, an external device can feed patterns to the
DLPC300 for display. Figure 4-3 shows the bit planes and corresponding output triggers for 3-bit, 6-bit,
and 12-bit RGB.
Figure 4-3. Bit Planes and Triggers
While an external device is writing a frame to the DLPC300, the previous frame is displayed. Therefore,
there is a lag of one video frame in relation to the output trigger signal.
Table 4-1 shows the allowed pattern combinations in relation to the bit depth of the external pattern.

Internal Patterns
In addition to the externally-provided sequences through the 24-bit RGB interface of the DLPC300, the
DLP LightCrafter offers the ability to preload patterns into the DLPC300’s memory (mDDR) to achieve
faster frame rates. After the patterns are preloaded, the FPGA manages the bit planes stored in the
mDDR. The mDDR accommodates four 608 × 684 images of 24-bit RGB data or 96 bit-planes (24 bitplanes × 4 images). The bit planes' arrangement and loading procedure is discussed in section 3.2 of
DLP® LightCrafter™ FPGA Overview, DLPA042
With the FPGA, the pattern frame rate can be calculated with the following equation:
Case 1: If the bit planes can be accommodated in single 24-bit buffer that is number of bit planes ≤ 24
Pattern Rate = 1 / (Pattern Exposure Period) Hz
(2)
Case 2: If the bit planes take more than 24-bit buffer that is number of bit planes > 24
Pattern Rate = (1 / Pattern Exposure Period) + (Bit Plane Load Time) + (Buffer Rotate Overhead)
where
•
•
Typical bit plane load time = 230 µs
Typical buffer rotate overhead = 135 µs
(3)
Table 4-2 shows the maximum pattern rate that can be achieved by using a single FPGA’s internal buffer
in continuous mode.

These locally stored patterns have a pre-defined exposure time that is detailed in Table 4-3. Note that the
exposure time decrements by 500 µs from the maximum exposure time. Thus, the minimum might not be
a step size decrease from the second to last minimum exposure time.

NOTE: The minimum exposure times hold good if the patterns fit into 1-frame buffer 24 bit plane
memory else the pattern minimum exposure time is increased by 135 µs.
For example: A pattern sequence consisting of 11 2-bit patterns can be fitted into 1-frame
buffer 24-bit plane area and so the minimum exposure time is 666 µs. However, a pattern
sequence consisting of 14 2-bit patterns extends into the second buffer, so the user needs to
add additional 135 µs as minimum pattern exposure time and it becomes 666 + 135 µs.
