The light engine includes the DLP4500 0.45-inch DMD with 1039680 mirrors, each 7.6 µm, arranged in
912 columns by 1140 rows with the diamond pixel array geometry and configuration (see Figure 1-3 and
Figure 1-4). Due to the diamond pixel configuration, the array produces smooth diagonal lines, with jagged
vertical and horizontal lines, as shown in Figure 1-5. Two options exist to produce the vertical and
horizontal lines: use every row or column, or use every other row or column. When every row or column is
used, a more thick line is projected. When every other row or column is used, a more faint line is
projected.

DLPU011F – July 2013 – Revised July 2017
Quick Start
This chapter details the steps to power up the DLP LightCrafter 4500 and connect to a PC.
2.1
Power-up the DLP LightCrafter 4500
The DLP LightCrafter 4500 is ready to use, out of the box. Steps 1 through 5 show how to power, display
an image, and connect the device to a PC.
1. Connect a 12-V DC power supply to the power supply connector (connector 2 in Figure 1-8).
2. An LED on the bottom of the DLP LightCrafter 4500 board, next to the flex cable lights up green. The
fan starts, stops, and then restarts while the DLPC350 is booting. After 5 to 10 seconds, the DLPC350
bootloads and displays a screen with the DLP logo and DLP LightCrafter 4500 logo. The D4 LED on
top of the DLP LightCrafter 4500 board flashes on and off green. If the board shuts down after briefly
turning on the display, the power supply current rating might be too low.
3. To display video, connect a DVI source to the mini-HDMI connector (connector 20 in Figure 1-8).
4. Control the DLP LightCrafter 4500 with the free GUI software (available to download from
http://www.ti.com/tool/dlplcr4500evm).
5. After installing the software on the computer, connect the PC to the DLP LightCrafter 4500 using a
USB to mini-USB cable (connector 4 in Figure 1-8). The first time the cable is connected on a PC, the
DLP LightCrafter 4500 emulates a USB composite device with human-interface device (HID) class. No
drivers are required because these drivers are natively handled by all operating systems.

Operating the DLP LightCrafter 4500
This chapter introduces the PC software provided with the DLP LightCrafter 4500.
3.1
DLP LightCrafter 4500 Software
The DLP LightCrafter 4500 includes a QT-based GUI application to control the module through the USB
interface. QT is a Nokia cross-platform application and user-interface framework with open source and
commercial licenses. To install the QT GUI, just expand the LightCrafter4500_GUI.zip file into a directory
and double-click on the executable file.
The DLP LightCrafter 4500 supports three main modes of operation:
• Video mode displays images from:
– DVI input through the mini-HDMI connector
– 24-bit RGB bitmaps stored in flash memory
– 24, 20, 16, 10, and 8-bit RGB input through the system board connectors (J1, J3, J4, and J6)
– Internal test patterns
– 30-bit RGB through flat panel display (FPD) link
• Pattern Sequence mode displays images from:
– 1-, 2-, 3-, 4-, 5-, 6-,7-, and 8-bit bitmap images stored in flash memory
– 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit bitmap images streamed through the DLPC350 24-bit RGB
interface (mini-HDMI, FPD-link, or system board connectors)
– The chosen pattern exposure and pattern period times apply to all patterns in the pattern sequence
• Pattern Sequence [Variable Exposure] mode displays images from the same sources as Pattern
Sequence mode:
– 1-, 2-, 3-, 4-, 5-, 6-,7-, and 8-bit bitmap images stored in flash memory
– 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit bitmap images streamed through the DLPC350 24-bit RGB
interface (mini-HDMI, FPD-link, or system board connectors)
– This mode allows for the pattern exposure time and pattern period to be set per pattern in the
pattern sequence
3.2
PC Software
Upon execution of the LightCrafter4500.exe file, the window shown in Figure 3-1 displays. The GUI
window contains the following two sections:
• The top portion of the GUI window displays the System Control and controls the Operating Mode,
Image Orientation, LED Driver Control settings, and LED Selection. There are also controls for saving
and applying solutions.
• The bottom portion of the GUI window offers a set of tabs to further control the selected Operating
Mode.
In any of the GUI sections, clicking a Get button reads the current settings of that particular subsection.
Clicking the Set button programs the settings in the respective subsection. Some commands may require
additional steps before the GUI display is updated.

Figure 3-1. DLP LightCrafter 4500 GUI – Video Mode
The DLP LightCrafter 4500 GUI communicates with the DLPC350 using USB 1.1. The DLPC350 emulates
as a USB device with HID support. The PC polls all the HID peripherals and once the PC detects the
DLPC350, the Connected button changes to green. If the USB cable is disconnected, the color of the
Connected button changes to red and the Connected text is grayed-out. Once the System Status shows
Connected, the firmware version, firmware tag, hardware, and System Status indicators are displayed.
There is no need to press the Connected button, because the HID peripheral is detected by the operating
system after USB enumeration.
3.2.1 System Status
At the top-left portion of the GUI window, the hardware and System Status indicators report the following:
• Init Done: When highlighted green, it indicates the successful completion of the DLPC350 initialization.
When highlighted grey, it indicates the DLPC350 had an error during initialization.
• Sequencer Running: When highlighted green, the DLPC350 sequencer is running as usual. When
highlighted gray, the DLPC350 sequencer is stopped.
• DRC Error: DMD Reset Controller Error indicator. When highlighted grey, the DMD Reset Controller
has not detected an error. When highlighted red, the DMD Reset Controller has found multiple
overlapping bias or reset operations accessing the same DMD block of micromirrors.

Forced Swap: When highlighted red, the DLPC350 sequencer detected a forced buffer swap error
indicating that image data has been displayed from the wrong internal display buffer. When highlighted
gray, no buffer swap error has occurred. This error can occur if the DLP LightCrafter 4500 is set to
Video Mode and the vertical backporch timing is too small. The error can also occur if the DLP
LightCrafter 4500 is set to Pattern Sequence mode with patterns input from the video port and pattern
sequence timings do not match the video port VSYNC.
Sequencer Error: When highlighted red, the DLPC350 sequencer has detected an error. When
highlighted gray, the DLPC350 sequencer detected that no error occurred.
DMD Parked: When highlighted yellow, the DMD micromirrors are parked in the position normal to the
DMD plane. When highlighted gray, the DMD micromirrors are not parked.
Buffer Freeze: When highlighted yellow, the frame buffer is frozen. When highlighted gray, the frame
buffer is not frozen. This is cleared on the next buffer swap.
Sequencer Abort: When highlighted red, the DLPC350 sequencer has detected an error condition that
caused an abort. When highlighted gray, the DLPC350 sequencer detected that no error occurred.
These indicators are updated every 2 seconds, or when a command is issued to the DLPC350.
•
Auto Update Status. When checked, all indicators will continue to update every two seconds. When
unchecked, the indicators will stop updating and turn gray. While running in Pattern Sequence Mode,
keeping the option unchecked prevents the GUI from interrupting the DLPC350 controller which will be
processing critical functions related to pattern display.
3.2.2 Operating Mode
To the right of the System Status, the Operating Mode sets how the DLP LightCrafter 4500 operates:
• Pattern Sequence mode: The DLPC350 takes 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit data from one of the
following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Flash memory
•
•
•
The DLPC350 does not apply any video processing functions and provides a pixel accurate mode
where every pixel maps to the native DMD resolution of 912 × 1140.
Pattern Sequence [Variable Exposure] mode: The DLPC350 takes 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 8-bit
data from one of the following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Flash memory
This mode differs from Pattern Sequence mode in that the pattern exposure time and pattern period
can be varied per pattern in the pattern sequence.
The DLPC350 does not apply any video processing functions and provides a pixel accurate mode
where every pixel maps to the native DMD resolution of 912 × 1140.
Video Mode: The DLPC350 takes 24, 20, 16, 10, and 8-bit data from one of the following interfaces:
– 24-bit RGB interface
– FPD-link interface
– Internal test pattern generator
– Flash memory
The DLPC350 then applies video processing functions, such as scaling, gamma correction, and color
coordinate adjustments, and sends the processed image to the DMD.
Power Standby: Places the DLPC350 in low-power state and powers down the DMD interface.

NOTE: If the DLP LightCrafter 4500 is disconnected from the USB and reconnected, the operating
mode may not reflect the mode it was just working in. This can occur in pattern sequence
modes when a pattern was not fully validated before being sent to the DLP LightCrafter
4500.
3.2.3 Image Orientation
Beneath Operating Mode, the Image Orientation controls the long and short axis flips to support front,
rear, table, and ceiling mounted projection. The Image Orientation occurs on the next image or frame load
in Video mode, and on the next download to the DLP LightCrafter 4500 in Pattern Sequence mode.
• East/West Flip: If checked, the image is flipped along the east and west axis of the projected image.
Usual table front projection has this setting unchecked. Otherwise, the image is flipped horizontally.
• North/South Flip: If checked, the image is flipped along the north and south axis of the projected
image. Usual table front projection has this setting unchecked. Otherwise, the image is flipped
vertically.

3.2.4 LED Current Settings
On the top-right of the GUI window, the LED Current settings control the individual currents of the red,
green, and blue LEDs. A setting of 255 corresponds to the maximum LED current. A setting of 0
corresponds to minimum LED current. The LED current is computed as follows:
Red LED Current (A) = 0.0175 × (LED Current Value) + 0.4495
Green LED Current (A) = 0.0181 × (LED Current Value) + 0.3587
Blue LED Current (A) = 0.0160 × (LED Current Value) + 0.1529

CAUTION
The DLP LightCrafter 4500 is an actively cooled system that has a thermal limit
resulting in total simultaneous red, green, and blue LED currents less than
4.3 A for continuous LED operation. Do not overheat the system by turning all
LEDs at maximum power during prolonged and simultaneous LED use.
Exceeding more than 4.3 A for continuous or simultaneous LED operation can
damage the DLP LightCrafter 4500 LEDs.

The LED Selection box determines the control of the LED enables signals. Two options are allowed:
• Automatic: LED enables are controlled by the DLPC350 sequencer. In Video Mode, the LED enables
are set in color sequential order. In Pattern Sequence mode, the LED enables are controlled by the
downloaded Pattern Sequence settings.
• Manual: LED enables are controlled by the check boxes. Checking a color, continuously enables the
LED of that color at the given LED current setting.
3.2.5 Video Mode
When the DLP LightCrafter 4500 is configured in Video Mode, the Input Source Select section in Figure 31 in the top-left part of the Video Mode tab selects the input source to be displayed by the DLPC350. The
DLPC350 treats these as video inputs and applies image processing functions, like scaling, gamma
correction, color coordinate adjustments, and so forth. The following lists the allowable input sources:
• Parallel RGB interface: Supports 24-, 20-, 16-, 10-, and 8-bit data inputs. This interface is connected to
the TFP401 for DVI input from the mini-HDMI connector or to the system board connectors. The Pixel
Data Format section is below the Source Select interface selects the allowable pixel data formats for
the Parallel RGB interface:
– RGB 4:4:4
– YCrCb 4:4:4
– YCrCb 4:2:2
• Internal Test Pattern: 24-bit internal pattern generator with RGB 4:4:4 pixel data format. The internal
test patterns offer color control of the foreground and background color of the pattern through the
Internal Test Pattern Color section. The available internal test patterns and their respective foreground
and background color control are:
– Solid field: Foreground color control only
– Horizontal ramp: Foreground color control only
– Vertical ramp: Foreground color control only
– Horizontal lines: Foreground and Background color control
– Diagonal lines: Foreground and Background color control
– Vertical lines: Foreground and Background color control
– Grid: Foreground and Background color control
– Checkerboard: Foreground and Background color control
– Red, green, and blue ramps: Foreground color control only
– Color bar: Foreground color control only
– Step bar: Foreground color control only
• Flash images: single-frame, 24-bit Still images stored in external flash memory. The flash memory
supports up to 32MB of storage with up to 64 images. The images stored in flash memory support
RGB 4:4:4 and YCrCb 4:2:2 pixel data formats.
• FPD-link: Flat Panel Display Link connector. The FPD-link interface supports 30-, 24-, 20-, 16-, 10-,
and 8-bit data inputs with RGB 4:4:4 pixel data format. The FPD Mode and Field Select configures the
mapping of the pixel mode, polarity, and CONT1 and CONT2 field signals.

For the Parallel RGB and FPD-link video input modes, the DLPC350 interprets channel A as green,
channel B as red, and channel C as blue. However, the Parallel RGB or FPD-link source can have
different mapping of channels to colors. The Input Source Port Data Swap section sets the mapping of
channels to colors. Port1 refers to Parallel RGB interface while Port2 refers to the FPD-link interface. The
mapping options are:
• ABC → ABC, no swapping of data subchannels
• ABC → CAB, data subchannels are right-shifted and circularly rotated
• ABC → BCA, data subchannels are left-shifted and circularly rotated
• ABC → ACB, data subchannels B and C are swapped
• ABC → BAC, data subchannels A and B are swapped
• ABC → CBA, data subchannels A and C are swapped
For all video input modes, the Display Dimensions section defines the active displayed resolution. The
maximum supported input and output resolutions for the DLP4500 0.45 WXGA DMD are 1280 pixels
(columns) by 800 lines (rows). The display area settings set the first pixel column (Start Pixel) and the first
line (Start Line) as well as, the numbers of pixels per line (total columns) and the number of lines per
frame (total rows). This setting also provides the option to define a subset of active input frame data using
pixel (column) and line (row) counts. In other words, this feature allows cropping of the source image as
the first step in the processing chain.
For the Parallel RGB and FPD-link video input modes, the Video Signal Information section provides
details about the video source connected to the DLP LightCrafter4500. These signal parameters can only
be read from the device, they cannot be set in the section.
The Signal Status parameter has the following states:
• Processing: The video source VSYNC signal has not yet locked when the Get Video Info button was
pressed
• Detected: The video source VSYNC signal has been locked
• Stopped: The DLP LightCrafter 4500 is no longer locking to the video source. This occurs in the
Pattern Sequence modes when video port input pattern streaming is selected. This prevents a delay in
pattern display if synchronization is temporarily lost with the video source.
• Lock Failed: The DLP LightCrafter 4500 was not able to lock to the incoming video source. Please see
sections 6.7 and 6.8 in the DLPC350 datasheet on Input Pixel Interface Timing Requirements to verify
the video input is meeting specifications.
3.3
Pattern Sequence Mode
When the DLP LightCrafter 4500 is configured in Pattern Sequence mode, the DLPC350 supports 1-, 2-,
3-, 4-, 5-, 6-, 7-, and 8-bit images with a 912 columns × 1140 rows resolution. These images are pixel
accurate, meaning that each pixel corresponds to a micromirror on the DMD and is not processed by any
of the video processing functions. Three subtabs control the Pattern Sequence settings: Sequence
Settings, Pattern Sequence Start/Stop/Pause, Trigger Controls, and LED Delay Control.
3.3.1 Sequence Settings
A pattern sequence is composed of several patterns loaded from flash memory or streamed through the
24-bit RGB video port. Each individual pattern can have a specific set of LEDs illuminating it, a particular
bit-depth, and an internal or external trigger. The Sequence Settings subtab lets the user define and set all
the Individual Pattern Settings. The Trigger Controls subtab and the LED Delay Control subtab set the
trigger and LED enable edge timings, respectively. The Pattern Sequence Start/Stop/Pause tab shows the
pattern sequence validation status indicators and allows the user to play, pause and stop the sequence.
Figure 3-5 shows the DLP LightCrafter 4500 GUI with the Pattern Sequence tab selected.

www.ti.com
Figure 3-5. DLP LightCrafter 4500 GUI – Pattern Sequence Mode
The Pattern Sequence displays images from one of the following two input sources:
• Flash: Images stored in flash memory. The flash memory can store up to sixty-four 24-bit compressed
images.
• Video port: Streamed through the Parallel RGB or FPD-link interface. Only one of these interfaces can
be connected to the DLP LightCrafter 4500 during Pattern Sequence mode.
To synchronize a camera or external system with the displayed patterns, the DLP LightCrafter 4500
supports a set of trigger inputs and outputs. These inputs and outputs are configured through the Trigger
Mode section and Trigger Controls subtab. The Trigger Mode selects the trigger input:
• Internal/External: Uses an internal trigger period to start the pattern sequence or uses the DLP
LightCrafter 4500 TRIG_IN2 signal to start and pause the pattern sequence. Each pattern in the
pattern sequence can be configured with either an internal or external trigger. With the Internal Trigger
setting, the Internal Trigger Period displays the next pattern. With External Trigger Period, the DLP
Light Crafter 4500 TRIG_IN_1 signal displays the next pattern.
• Vsync: Uses the VSYNC signal from the Parallel RGB or FPD-link interface to trigger the start of the
pattern sequence. After VSYNC, the patterns are displayed in the sequence shown on the Pattern
Sequence section. Each pattern length is determined by the Pattern Exposure time. Thus, the total
number of patterns multiplied by the pattern exposure must be less than or equal to the VSYNC period.

Pattern sequence timing is controlled by the Pattern Period and Pattern Exposure time.
• Pattern Exposure (us): Defines the amount of time a single pattern is displayed in microseconds.
• Pattern Period (us): Defines the amount of time between patterns (in microseconds) in a pattern
sequence.
A pattern sequence can be any combination of bit depth patterns with any combination of LED sources.
The pattern sequence can be played once or continuously repeated. The allowed LED sources are:
• White: Red, green, and blue LEDs on
• Cyan: Green and blue LEDs on
• Magenta: Red and blue LEDs on
• Yellow: Red and green LEDs on
• Red: Only red LED on
• Green: Only green LED on
• Blue: Only blue LED on

create a pattern sequence, follow these steps:
Choose pattern input source (Flash or Video port) from the Pattern Source section.
Choose Internal/External, or VSYNC trigger mode from the Trigger Mode section.
Set the appropriate Trigger Controls, see Section 3.3.4
Set the Pattern Exposure period and Pattern Period.
Create the pattern sequence in the Individual Pattern Settings section:
(a) Choose the LED(s) to illuminate this pattern in the pattern sequence
(b) Select the trigger for the pattern: no trigger, external positive, external negative, or internal trigger.
Internal trigger has an internal hardware signal that is input to the pattern display state machine
(meaning the controller starts displaying after receiving the signal), whereas the no internal trigger
option will display a pattern without waiting for a trigger; each pattern will display in continuation
with the previous pattern. Creating an internally triggered pattern sequence with an external trigger
input may cause unexpected behavior.
(c) Choose the Flash Index (for Flash Pattern Source) or the Frame Index (for Video port Pattern
Source) and set the bit depth for the pattern.
(i) Flash Index: This is the image's index in flash as bundled with the firmware loaded on the DLP
LightCrafter 4500. These images can be viewed in Video mode by changing the Input
Configuration > Source Select to Images from Flash
(ii) Frame Index: This value can be left alone. The patterns will be pulled from the specified bitplane(s) from each transmitted video frame sequentially
Note: In pattern sequence mode, a group of images are sent in parallel rather than a single
standard 24 bit RGB image, and anywhere from 3 8-bit images (grayscale) to 24 individual 1-bit
images are sent. The color for each pattern in the sequence is determined by the LEDs selected
when that pattern was added to the sequence.
(d) Select the desired pattern bit-depth to be displayed. The bit-planes are labeled G0 - G7, R0 - R7,
and B0 - B7. Clicking on a rectangle will select this bit-plane. The grouping of bit-planes is
determined by the bit-depth selected. The groupings cannot be changed. When the source is the
video port, the trigger will always be VSYNC and the VSYNC period will be the total available time
for displaying patterns (i.e. the video frame will be updated on each VSYNC). The number of
patterns that can be displayed in this time is set by the pattern exposure and pattern period times
selected.
Note that if using the video port, the incoming image resolution must be 912x1140
(e) If a black image is desired between patterns, check the Clear DMD after exposure.
(f) Click the Add Pattern to Sequence button.
(g) Repeat Steps through for each pattern in the sequence.

in Table 4-1.
• Pattern Number OOR: When highlighted red, the Pattern Number is out of range. The maximum
allowed patterns depend on the bit width and are listed in Table 4-1.
• Cont trig out overlaps black: When highlighted red, the continuous pattern exposure has a trigger
Out1 request or overlapping black sectors.
• Black vector missing: When highlighted red, the black vector is missing (this may also be referred
to as the post vector).
• Period, Exposure diff < 230: When highlighted red, the difference between the frame period or
internal trigger period and the exposure period of a pattern is less than 230 µs. The DMD needs
230 µs for load a pattern, so the trigger or frame period must be 230 µs greater than the pattern
exposure time.
8. Pause or restart the pattern sequence through the Pause and Play buttons, respectively. If a pattern
sequence was previously loaded, the user can click the Read button to load the sequence into the GUI
window.
The Pattern Sequence section in the Sequence Settings tab shows the pattern sequence as a set of
colored rectangles. The color corresponds to the LEDs used. The entries on the rectangles represent the
image source, the bit-plane, and the bit-depth as follows: S0::G0 (1) indicates flash location 0, bit-plane =
G0, bit-depth = 1. F2::G5 (3) indicates Frame 2, bit-plane = G5, bit-depth = 3. For example, in Figure 3-5,
a pattern sequence of three patterns is displayed. Each pattern is triggered every 500 ms and exposed for
500 ms. The first pattern is a 1-bit red pattern using bit-plane G0 from flash location 0. The second pattern
is a 1-bit green pattern using bit-plane G1 from flash location 0. The third pattern is a 1-bit yellow pattern
using bit-plane G2 from flash location 0.
A pulse icon in between the patterns indicates that a trigger is needed between the patterns. Right-clicking
on this icon allows the removal of the trigger, so two or more patterns can share the same trigger and are
exposed in sequence for the total exposure time. Right-clicking on a pattern allows the option of inverting
the pattern, removing the pattern, or inserting a black image by clearing the DMD after exposure time.

A typical time is 200 ms. Once an image is loaded from flash, 24 bit-fields reside in the frame buffer and
can be sequenced at higher speeds. Two 24-bit field display buffers are available in the DLPC350. If the
pattern sequence uses more than two images (48-bit fields), then approximately 200 ms is required to
load the new image into the DLPC350 internal display buffer.

Storing Images in Flash Memory
LightCrafter 4500 allows images to be compressed and stored into the 32-MB flash memory. For most
efficient storage and compression of images, stored images are packed into groups of 24-bit RGB bitmap
images and decompressed on the fly while loaded from flash memory. To ease the packing of any bit
width images, the LightCrafter 4500 GUI offers the Create Images subtab, see Figure 3-14. To create a
24-bit image from different multiple bit depth images, perform the following steps:
1. Select the Image / Firmware tab and the Create Images subtab.
2. Select a bitmap file with 912 columns by 1140 rows by clicking the ... button next to Input bmp file
3. Select Output bitmap file by clicking the ... button next to Output bmp file
4. For an input file, add the individual bit-planes by repeating the following process:
(a) Set the bit depth and the bit field position with the Bit depth and the At bit position pulldown
selectors, respectively.
(b) Click the Add to Output File button. The current image is bit weighted and saved into the 24-bit
image of the output file.

DLPU011F – July 2013 – Revised July 2017
Pattern Sequences
This chapter describes the pattern sequences supported by the DLP LightCrafter 4500 module.
4.1
Pattern Sequence Background
The DLPC350 takes as input 24-, 27-, or 30-bit RGB data at a frame rate of up to 120-Hz. This frame rate
is composed of three colors (red, green, and blue) with each color equally divided in the 120-Hz frame
rate. Thus, a 2.78-ms time slot is allocated to each color. Because each color has 8-, 9-, or 10-bit depth,
each color time slot is further divided into bit-planes. A bit-plane is just a 1-bit representation of all the
pixels in the image. For example, 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.

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 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 loaded to the DLPC350, the DLPC350 creates 24
bit-planes, stores them in its internal display buffer, and sends the bit-planes to the DLP4500 DMD, one
bit-plane at a time. Depending on the bit weight of the bit-plane, the DLPC350 controls the time this bitplane 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 DLPC350.
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 signals for the camera to capture these patterns
overlaid on an object.
As shown in Figure 4-3, the DLPC350 stores two 24-bit frames in its internal memory buffer. This 48 bitplane display buffer allows the DLPC350 to send one 24-bit buffer to the DMD array while the second
buffer is filled from flash or streamed in through the 24-bit parallel RGB or FPD-link interface. In streaming
mode, the DMD array displays the previous 24-bit frame while the current frame fills the second 24-bit
frame of the display buffer. Once a 24-bit frame is displayed, the buffer rotates providing the next 24-bit
frame to the DMD. Thus, the displayed image is a 24-bit frame behind the data streamed through the 24bit RGB parallel or FPD-link interface.
Figure 4-3. DLPC350 Internal Memory Buffer
When the DLP LightCrafter 4500 is set to Video Mode, the displayed image is a frame delayed in relation
to the data streamed through the RGB parallel interface or FPD-link, as shown in Figure 4-4.

Figure 4-4. Frame Delay Between Parallel Interface Input and Projection Output
When the DLP LightCrafter 4500 is set to Pattern Sequence mode with pattern source from flash, the
pattern sequence must be loaded from flash memory. The DLPC350 takes at-worst-case 200 ms to load
one buffer (24 bit-planes). The actual time to load the buffer depends on the complexity of the image. The
actual time is provided in the Image / Firmware tab under Image Load Time. If the pattern sequence is
less than 24 bit fields, the patterns are displayed from a preloaded buffer. Once the patterns are loaded,
the pattern sequence repeats from the internal display memory with no buffer load penalty. If the pattern
sequence is greater than 24 bit-fields, the 24 bit-field pattern sequence display time must be longer than
the full buffer load time. This provides enough time to load the next buffer while the current buffer is
displayed. See Figure 4-5 for a diagram of Image Load Time, Pattern Exposure Trigger period, and
Internal Trigger period.
Figure 4-5. Image Load Time and Pattern Sequence Timing
In pattern sequence mode, the 48 bit-planes can be preloaded from flash memory and then sequenced
with a combination of patterns with different bit depths. To synchronize a camera to the displayed
patterns, the DLPC350 supports two trigger inputs and two trigger outputs. TRIG_IN_1 pulse indicates to
the DLPC350 to advance to the next pattern, while TRIG_IN_2 starts and stops the pattern sequence.
TRIG_OUT_1 frames the exposure time of the pattern, while TRIG_OUT_2 indicates the start of the
pattern sequence or internal buffer boundary of 24 bit-planes. For example, in Figure 3-10, the VSYNC
starts the pattern sequence display. The pattern sequence consists of a series of three consecutive
patterns. The first pattern sequence consists of P1, P2, and P3. P3 is an RGB pattern, it is shown with its
time-sequential representation of P3.1, P3.2, and P3.3. The second pattern sequence consists of three
patterns: P4, P5, and P6. The third sequence consists of P7, P8, and P9. TRIG_OUT_1 frames each
pattern exposed, while TRIG_OUT_2 indicates the start of each of the three pattern sequences. In
Figure 3-11, a pattern sequence of a group of four patterns are displayed. TRIG_OUT_1 frames each
pattern exposed, while TRIG_OUT_2 indicates the start of each four-pattern sequence. TRIG_IN_1 pulses
advance the pattern.

Saving Solutions
On GUI software version 1.2 or later, any of the parameters set on the GUI can be stored as a solution.
This solution can later be recalled with a single button or set to run as default on powerup. Temporary
solutions are essentially .ini files that contain all the current parameter settings on the GUI. The .ini file is
stored on the PC. To create a new default solution, the .ini file must be built into a new firmware image.
This chapter describes the processes for creating, loading, and storing solutions.
5.1
Applying Solutions
This feature refers to the temporary solutions saved as .ini files on the PC. Three buttons in the static
panel of the GUI control the application and creation of these solutions: Apply Solution, Save Solution,
and Apply Default Solution.
• Apply Solution: Click this button to browse for .ini solutions that are already saved. Upon selecting an
.ini file, the corresponding parameters update in the GUI. Parameters the user cannot change in the
GUI (version number and splash time-out) do not take effect.
• Apply Default Solution: This button restores the settings to match those of the original DLPC350
firmware. Clicking this button is effectively the same as saving a solution and only selecting the values
in the first column of radio buttons.
• Save Solution: Click this button to make a new window with a list of several parameters (described in
Section 5.3.1) appear. One column of radio buttons contains the values set in the original DLPC350
firmware. The second column of radio buttons contains the values currently set in the GUI. The user
can select either the original or current values to store in the .ini file
5.2
Changing Default Solutions
This feature refers to the process of taking an .ini file and building it into a new firmware image. The
following procedure should be followed:
1. Select the Image / Firmware tab and the Add Images to Firmware subtab.
2. Choose a base firmware file. The Select .ini File button becomes active and lets the user browse for
an .ini file.
3. Once the .ini file is selected, click the Save Updates button to save a new firmware image file.
4. Upload this new .bin or .img file to the LightCrafter 4500. The LightCrafter 4500 boots with the settings
specified in the .ini file, and returns to these settings if reset.
NOTE: There are a few limitations to the use of .ini files and saved solutions. The first is that any
saved solution using video streaming mode or video source input will not work on startup due
to the Lightcrafter 4500 needing time to lock onto a video source. All other settings will be
configured as desired.
Second, connecting the Lightcrafter 4500 to the GUI pauses any running system activity.
This means any saved solutions utilizing repeated pattern sequences on start up will be
stopped once connected to the GUI.

5.3.2 Save Solution Button
When this button is clicked in the GUI, a new window with a subset of parameters from Table 5-1 appear.
One column of radio buttons contains the original values of the DLPC350 firmware. The second column of
radio buttons contains the values currently set in the GUI. Select which value or values are needed in the
.ini file. This method is the preferred way of previewing syntax errors or invalid entries.
5.3.3 Manual Editing
The .ini files can be edited as text files. This method does not check syntax or validate commands. TI
recommends this method only for editing those commands not available through the GUI
(APPCONFIG.VERSION.SUBMINOR, DEFAULT.AUTOSTART, PERIPHERALS.I2CADDRESS,
DATAPATH.SPLASHSTARTUPTIMEOUT, and DATAPATH.SPLASHSTARTUPENABLE). This method
can be used with the LUT Helper Tool provided in the software bundle for DEFAULT.SPLASHLUT and
DEFAULT.SEQPATLUT. For more information about the tool, Section 5.3.4.
5.3.4 LUT Entry Helper Tool
The LUT Entry Helper Tool has four tabs. The first two tabs can be used to calculate the values for
DEFAULT.SEQPATLUT and DEFAULT.SPLASHLUT. The second two tabs are for reference.
5.3.4.1
Pattern LUT Entries
This tab is used to calculate the values for DEFAULT.SEQPATLUT. The table with 128 possible entries
can be modified with the desired parameters for each pattern in the pattern sequence. It is possible to
customize various parameters for each pattern. Valid entries for each category below are found in the
Data tab.
• BIT-DEPTH: Select between 1 and 8.
• PATTERN: Select the desired pattern number. Each bit-depth of n corresponds to a pattern number
equal to 24 / n. See the Pattern Bit-Planes tab to understand the mapping of bit-planes to pattern
number.
• LED: Select which LEDs are on.
• TRIG IN: Select the type of trigger input that will trigger the current pattern. If streaming through the
video port, the VSYNC acts as the External Positive trigger, and any subsequent patterns in the frame
(between VSYNC pulses) have no trigger. These patterns are labeled with Continue in the Pattern
Sequence window.
• PAT INVERT: Select whether or not to invert the pattern.
• INSERT BLK: Select whether to clear the DMD after each pattern or not. TI recommends clearing the
DMD at least after the last pattern in the LUT.
• BUFF SWAP: This parameter indicates whether or not to move to the next flash image in the
SPLASHLUT. Each time this is a yes, the SPLASHLUT index increments. The index returns to 0 if
there are no more indexes.
• TRIG OUT: Either a new Trigger Out1 is generated (NEW) or the pattern shares exposure time with
the previous pattern (PREV) and no output trigger is generated.
As the user changes the values in the LUT, the values in the LUT DATA column change. After entering
the parameters for as many patterns as needed, scroll to the bottom of the sheet. Enter the total number
of patterns next to N = (in cell C138). Then, row 139 generates the necessary values the user must copy
into the .ini file.
Lastly, there is a Debug Helper tool at the bottom of this sheet. Enter a hex code where it says LUT DATA
to find out what the corresponding parameters are.
5.3.4.2
Image LUT Entries
This tab is used to calculate the values for DEFAULT.SPLASHLUT. This tab converts the desired image
indexes into hexadecimal values. Row 6 contains the calculated string of values for the .ini file. If the user
repeats indexes, enter them separately. See this example in Table 5-2; the order is 0, 13, 12, 1, 13, 12, 0,
13, 12, 1, 13, 12, and so on.

PandaBoard Interface
This chapter describes the interface between the DLP LightCrafter 4500 and the PandaBoard ES.
6.1
PandaBoard 4500
PandaBoard ES is a low-cost, open-development platform based on the TI OMAP4 application processor.
The PandaBoard ES is supported by a dedicated community at PandaBoard.org. The DLP LightCrafter
4500 combined with a PandaBoard ES provides users with an embedded platform that eliminates the
need for a dedicated laptop or PC. The PandaBoard ES includes an OMAP4 1.2-GHz, dual-core
processor, 1GB of onboard RAM, SD card slot, and a suite of connectivity options, including:
• Ethernet, Bluetooth®
• Wi-Fi
• USB 2.0
• HDMI output and a camera input connector.
The combination of PandaBoard ES with DLP LightCrafter 4500 allows for the creation of self-contained,
high-precision mobile tools to meet a growing number of applications, such as inline machine vision
systems, portable, high-accuracy 3D scanners, and field spectrometers.
To
•
•
•
•
•
•
interface a PandaBoard ES with the DLP LightCrafter 4500, the following modifications are needed:
Populate J1 with Samtec FW-10-04-F-D-570-140
Populate J3 with Samtec ZW-14-10-F-D-415-200
Populate J4 with Samtec FW-10-04-F-D-570-140
Populate J6 with Samtec ZW-14-10-F-D-415-200
Remove resistor R152 on the PandaBoard ES. The DLP LightCrafter 4500 powers the PandaBoard.
Removing the resistor prevents the PandaBoard from being powered by the USB and conflicting with
the DLP LightCrafter 4500 power.
Add four metric male-female threaded hex standoffs with a length of 19 mm and a M3 screw size
Due to the tight tolerances in the J1, J3, J4, and J6 connectors alignment, TI recommends inserting these
headers on the corresponding DLP LightCrafter 4500 connector before soldering. For ease of use,
SVTronics® has created a custom-build option of the PandaBoard ES that includes the connectors and
standoffs, and removes the R152 resistor, called PandaBoard 4500. Figure 6-1 shows a DLP LightCrafter
4500 with a PandaBoard 4500.

Figure 6-1. DLP LightCrafter 4500 With PandaBoard 4500
6.1.1 DLP LightCrafter 4500 to PandaBoard Interface
As shown in Figure 6-2, the DLP LightCrafter 4500 supplies 5-V power to the PandaBoard. The
PandaBoard provides 1.8 V to the DLP LightCrafter 4500 to level-shift all the signals interfacing the two
boards together. The following OMAP4 GPIOs control the routing of OMAP4 peripherals to the
corresponding DLPC350 peripherals:
• To power down the output of TFP401 and enable the level shifters in the 24-bit RGB interface, the
OMAP4 processor must drive GPIO_140 (SYS_MSTR_MUX_SEL) high.
• To connect the OMAP4 USB3 bus to the DLC350, OMAP4 must drive GPIO_39 (SYS_USB_SEL)
high.
• To connect the OMAP4 I2C2 bus to the DLPC350 I2C1 bus, OMAP4 must drive GPIO_51
(SYS_I2C_OE) high.
• To disconnect UART output of DLPC350 from J20 and route it to OMAP4 UART4, OMAP4 must drive
GPIO_33 high.
• To connect the triggers from DLPC350 to OMAP4 GPIOs, OMAP4 must drive GPIO_61
(SYS_TRIGGER_SEL) high.
Table 6-1, Table 6-2, Table 6-3, and Table 6-4 list the signals interfacing the OMAP4 processor in the
PandaBoard 4500 with the DLPC350 in the DLP LightCrafter 4500.

6.1.2 PandaBoard Software
Note: Only up to revision B2 of the PandaBoard are officially supported
The HDMI connector is the default display output of PandaBoard. To reroute the display video output to
the RGB interface of the DLP LightCrafter 4500, the kenrel config file must be modified with the following
changes:
• Disable DRM
• Enable DVI output
• Enable frame buffer support
To perform these changes, obtain the Ubuntu® kernel from the repository:
• git clone git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git
• git checkout -b working origin/ti-omap4
Install ARM compilers on Linux® machine:
• sudo apt-get install gcc-arm-linux-gnueabihf cpp-arm-linux-gnueabihf
• sudo apt-get install gcc-arm-linux-gnueabi cpp-arm-linux-gnueabi
To run the menuconfig, install ncurses package:
• sudo apt-get install build-essential ncurses-dev
Before compiling the Ubuntu kernel, the DVI port must be enabled. Run menuconfig:
• cp debian.ti-omap4/config/config.common.ubuntu.config
• sudo make ARCH=arm menuconfig
Select the following:
• Disable DRM under: Device Drivers → Graphics Support → Direct Rendering Manager
• Enable DVI under: Device Drivers → Graphic Support → OMAP2+ Display Subsystem support →
OMAP2/3 Display Device Drivers → DVI Output
• Enable frame buffer support: Device Drivers → Graphic Support → OMAP2+ Display Subsystem
support → OMAP2+ frame buffer support
Build the kernel:
• ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make
Generate the uImage:
• ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make uImage
The generated uImage will be located at ubuntu-precise/arch/arm/boot/uImage.

To configure the OMAP4 LCD peripheral drive for the DLP LightCrafter 4500 24-bit RGB input, perform
the following changes to the boot script. The boot script, boot.scr, is used by U-Boot.
• Set the DVI as the default output by adding the following entry to boot.scr:
– omapfb.mode=dvi omapdss.def_disp=dvi
• Set the desired resolution fro the DLP LightCrafter 4500 output by adding one of the following entries
to boot.scr:
– omapfb.mode=dvi:912x1140MR-24@60
– omapfb.mode=dvi:1280x800MR-24@60
• Generate the boot.scr:
– mkimage -A arm -T script -C none -n "Boot Image" -d boot.script boot.scr
• Copy the generated uImage and boot.scr in the boot partition of the SD card.
Make the modules:
• Make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm INSTALL_MOD_PATH=
modules_install
Copy the ‘modules’ folder from the path given in the previous command to the \lib folder on secondary
partition.
