1.5.1 DLP LightCrafter Dual DLPC900 LED Enable and PWM Outputs
The LED enables on J26 are low-current 3.3-V outputs and are not to be used to drive LEDs directly. The
enables are to be used as a control to enable a regulator that provides the necessary current to the LEDs.
The PWM outputs are also 3.3-V outputs and used for controlling the current to the LEDs, which controls the
brightness.
Note
The 12-V DC output on J26 are not to be used to power the LED drive circuitry since it does not
provide the necessary current when all three LED enables are simultaneous turned on. Doing so can
cause a drop in the 12-V supply to the EVM regulator circuitry and reset the controller.

DLP LightCrafter Dual DLPC900 EVM Overview
1.5.2 DLP LightCrafter Dual DLPC900 Trigger Input and Output Voltage Selectors
The trigger inputs on J23 are inputs from external devices to control the pattern sequence. While trigger input 2
is high, trigger input 1 advances the pattern sequence to the next pattern in the sequence on every pulse.
The trigger outputs on J27 are outputs to control external devices. While trigger output 1 frames the exposure
time of the pattern, trigger output 2 pulses to mark the beginning of each pattern.
Both input and output triggers have voltage level selectors. Use J22, J24, J25, and J28 to select the voltage
as shown in Figure 1-4. If no voltage is selected, then the onboard logic is not functional and any outgoing or
incoming signals are not available.

1.6 DLP LightCrafter Dual DLPC900 EVM Flex Cable
Electrical malfunctions can occur by stressing the flex cable(s) connecting the DMD circuit board to the
DLPC900 controller circuit board. Stressing the flex cable can be caused by:
• Bending the cable outside the area identified in Figure 1-5 (within 20.3 mm of connector plate centers).
• Repeatedly bending the flex cable(s) where the bend radius is less than 25.4 mm.
• A single bending of the flex cable(s) where the bend radius is less than 6.35 mm.

The minimum bend radius for forming flex cable (flexible) circuit is 6.35 mm
Use caution when bending the flex cable to not exceed bending guidelines explained above.
1.7 DLP LightCrafter Dual DLPC900 EVM and DMD EVM Assembly
The DLP Dual DLPC900 EVM requires a suitable DMD EVM listed in DLP LightCrafter Dual DLPC900
Evaluation Module (EVM) Hardware.
• The flex cables provided with the DMD EVM have one end marked "DMD End" with key pins arranged
diagonally that only fit one way onto the DMD board preventing attachment to the wrong side of the
board. Place the insulated backer plate on the other side of the DMD board from the flex side with
connection pins and carefully tighten the screws. Alternate tightening the screws from side to side until
the screws are firm, but not overtightened (SCREW TORQUE REQUIREMENT: 6-8 IN*LB [0.7-0.9 N*m]).
Assembled DLPLCRC900DEVM with DLPLCR90EVMshows the flex cable DMD ends correctly assembled to
an example DMD EVM board.
• The other end of the flex cables attach to the dual DLPC900 controller board. The key pins are arranged
laterally symmetric and can be inserted from either side of the controller board. To ensure the cables are
connected to the correct side of the dual DLPC900 controller board, check that the connection flex pins
are facing the pads as shown in DLPLCRC900DEVM Flex Cable Pads. Place the insulated backer plate
on the other side of the controller board from the flex with pins and carefully tighten the screws. Alternate
tightening the screws from side to side until the screws are firm, but not overtightened (SCREW TORQUE
REQUIREMENT: 6-8 IN*LB [0.7-0.9 N*m]). Assembled DLPLCRC900DEVM with DLPLCR90EVM shows the
flex cable ends correctly assembled to the dual DLPC900 controller board.

supported DMD EVMs. Steps 1 through 6 show how to power, display an image, and connect the EVM to a PC.
1.
2.
3.
4.
Connect a 12-V DC power supply to the power supply connector J20 in Figure 1-3.
LEDs — D5, D11, and D12 light up green to indicate configuration and power is normal.
LEDs — D7 and D9 toggle on and off, indicating the DLPC900 controllers are operating normally.
After 5 seconds, the two DLPC900 devices start sending a built-in rotating pattern sequence of images to the
DMD for display on the DMD.
5. Connect a USB cable from a PC to connector J8 on the DLP LightCrafter Dual DLPC900 EVM, as seen
in Figure 1-3. The first time the cable is connected on a PC, the DLP LightCrafter Dual DLPC900 EVM
enumerates as a USB composite device with human-interface device (HID) class. No drivers are required
since these are natively handled by all operating systems.
6. The DLP LightCrafter Dual DLPC900 EVM can be controlled with the free GUI software and firmware
versions available for download from DLPLCRC900DEVM.
Note
Be sure to install DLP LightCrafter GUI software version 5.0 and firmware 6.0 or newer. Operating
the DLP LightCrafter Single DLPC900 EVM with prior revisions of the GUI may render the EVM
inoperable.
Note
The DLPC900 does not have a dedicated INIT_DONE signal output to indicate that it has
completed its power-up initialization and is ready to accept commands. The user may configure
one of the nine GPIOs available as an INIT_DONE signal output simply by adding the GPIO
configuration into a default batch file that is executed at power-up. A 10-kΩ pull-down resistor
must be connected to the GPIO to be used.
The following is an example of adding the configuration for GPIO_08 to a batch file, where
GPIO_08 is configured as an output and the signal is set high. When this command is added
to the top of the batch file, the GPIO output goes high in approximately 800 ms from the time
POSENSE goes high.
GPIO_CONFIG: 0x8 0x3

2.2 Creating A Simple Pattern Sequence
Before creating a pattern sequence, make sure to follow the steps in Section 2.1. Download and execute the
latest DLPC900REF-SW Windows-Installer, and then start the DLP LightCrafter DLPC900 GUI application. The
GUI detects the attached EVM, and the Connected radio-button lights up Green indicating the connection was
successful. The GUI software includes sample images for the DLP LightCrafter Dual DLPC900 EVM that are
used in the examples in this guide. If the sample image files have not been unzipped during the installation
process, then within the GUI install directory, unzip the image files to gain access to all the sample images. All
images are 1-bit binary patterns and have the native resolutions of 2048x1200, 2560x1600, and 2716x1600 to
accommodate the different resolutions of the Dual DLPC900 EVM compatible DMD EVMs.
Follow these steps to create a pattern sequence. See Figure 3-7 to identify the buttons on the Menu bar.
1. Select Pattern On-The-Fly Mode from the Operating Mode group box, and click the Pattern Design button so
that the panel is displayed as shown in Figure 2-1.
2. Click the Add Pattern button (with the plus sign) in the Menu bar and browse for any three bitmap images
from the sample of images. The default directory location is C:\Texas Instruments-DLP\DLPC900REFSW-5.x\DLPC900REF-GUI\Images and Batch files\[DMD]_Images. Be sure to select them from the correct
image sub-folder for the EVM that is being used. All three images can be selected at the same time within
the open file dialog window, but may not appear in the same order in the GUI as in the dialog window.
Note
For the next three steps a selected pattern is indicated by a lighter gray selection area. See Figure
2-2 which shows the third pattern (pattern 2) selected.
3. Select the first pattern within the Pattern Design panel and choose a bit depth of 1. Set exposure to 100000
µs, dark time to 50000 µs, and select Red for the color.
4. Select the second pattern and choose a bit depth of 1. Set exposure to 150000 µs, dark time to 75000 µs,
and select Green for the color.
5. Select the third pattern and choose a bit depth of 1. Set exposure to 200000 µs, dark time to 100000 µs, and
select Blue for the color. Figure 2-2 shows the pattern sequence.
6. Select the Repeat radio-button to continuously repeat the pattern sequence.
7. Click the Update LUT button to upload the pattern sequence definition including the three pattern images to
the EVM.
8. Click the Start button to run the pattern sequence. The three selected patterns show for the timings entered
in steps 3, 4, and 5 and repeat until Step 9 is completed.
9. Click the Stop button to stop the pattern sequence.

3.3 System Common Controls
The DLP LightCrafter DLPC900 GUI communicates with the DLPC900 using USB 1.1. The DLPC900
enumerates as a USB device with HID Support. The PC polls all the HID peripherals and once the PC detects
the DLPC900, the Connected radio-button changes to green. If the USB cable is disconnected, the Connected
radio-button changes to red. Once the Connected radio-button shows green, the firmware Version and the Tag
name are displayed.
The Virtual Connection option is useful when there is no connection to the EVM. When the Virtual Connection is
checked, all commands continue to operate as if there was a connection to the EVM except for firmware uploads
and updating the Look Up Table (LUT).
3.3.1 Operating Mode
Within the System Controls group box, the GUI updates the state of the EVM to indicate it is in Normal Operation
or Standby Mode. The user may command the EVM into Standby Mode if the EVM is not being used or the
Normal Operation can be selected to command the EVM to wake up. The user may click the Reset button to
command the EVM to perform a software reset.

Operating the DLP LightCrafter Dual DLPC900 EVM
www.ti.com
Note
When in Standby Mode the GUI suspends status updates until a return to operation or SW reset is
issued. If a HW reset is asserted the GUI must be restarted to recognize return to operation.
Standby mode requires a wait period of two minutes to run 50/50 and park the DMD. Three additional
seconds are needed to complete all operations before issuing a Return to Normal command.
Once Standby has been issued the only command accepted by the DLPC900 controller board is
Return to Normal (0). Any other command can result in unexpected behavior. Particularly a Park/
Unpark is not accepted until Normal mode is resumed.
The EVM can be commanded to enter one of the four operating modes. Within the Operating Mode group box
there are four choices:
1. Video Mode – This mode is primarily used for display applications, and is not recommended for applications
which require pixel and timing accuracy. In this mode, the user can choose from the four following video
modes:
• Parallel RGB interface
• Internal test pattern generator with ten test pattern options
• Pattern image display from flash memory
• Solid Curtain with choice of color
2. Pre-stored Pattern Mode – In this mode, the user can create a pattern sequence using images stored in
flash.
3. Video Pattern Mode – In this mode, the user can define a pattern sequence using pattern data or video
which is streamed using a parallel RGB interface.
4. Pattern On-The-Fly Mode – In this mode, the user can create a pattern sequence using bitmap images
which are loaded into the internal memory of the DLPC900 via the USB or I2C interfaces. This mode can be
helpful to view a pattern sequence before storing the images in flash memory, as updating the flash to use
Pattern Mode can be a timely process.
3.3.2 Connected DMD Type
The GUI queries the DLP LightCrafter Dual DLPC900 EVM to determine the DMD type that the firmware is
programed for and is expecting to be connected to the DLP LightCrafter Dual DLPC900 EVM. The indicators in
the Chipset Type group box are updated to show which DLPC900 compatible DMDs is expected.
Note
The user must ensure that the firmware programmed into the Dual DLPC900 EVM matches the DMD
EVM attached.
3.3.3 EVM Information
The Introduction Main Page shows an image of the EVM currently connected and helpful links to online
resources.
3.3.4 Status
The Status panel indicators show the current state of the DLPC900. When any of the boxes are checked, this
indicates the stated text has occurred. Any boxes that state an error and remain checked must be corrected
before continuing to operate the EVM.
The following is a description of each status indicator:
•
•
24
Internal Memory Test Passed – The DLPC900 performs an internal system memory test at power-up. The
box is checked if the test passed.
Controller/DMD Incompatible – The box is checked if either the controller or DMD are incompatible with the
firmware including loading incorrect firmware or an issue with communication between the controller and
DMD. Check for possible damage to the SCP lines, or damage to the flex cables. Also ensure that the DMD
is sitting properly in the socket, and is not missing or damaged.

Operating the DLP LightCrafter Dual DLPC900 EVM
Secondary Present and Ready – The box is checked when the GUI is connected to a DLP LightCrafter
Dual DLPC900 EVM. If the GUI is connected to a DLP LightCrafter Dual DLPC900 EVM and the box is
not checked, then one or both of the DLPC900s are potentially malfunctioning or the EVM was incorrectly
programmed with a Single DLPC900 firmware file.
Internal Initialization Complete – The box is checked when all power-up initialization routines have completed
and passed.
DMD Reset Waveform Controller Error – The box is checked whenever the DMD Reset Controller has found
multiple overlapping Vbias or reset operations accessing the same DMD block of micromirrors.
Forced Buffer Swap – The box is checked whenever a forced buffer swap occurs. This error can occur if the
DLP LightCrafter Dual DLPC900 EVM is set to Video Mode and the vertical back-porch timing is too small.
The error can also occur if the DLP LightCrafter Dual DLPC900 EVM is set to Video Pattern Mode where
the patterns are from the video port and the pattern sequence timings do not match the video port VSYNC
- specifically the cumulative exposure times are greater than the frame time. Forced buffer swaps may also
occur during any of the pattern modes in preparing a pattern sequence and the timing of a status read. The
user may need to perform additional reads of the status to get a correct state of this indicator. If the box
continues to be checked, check for an error condition in the pattern sequence.
Sequence Abort Status Flag – The box is checked whenever a sequence abort has occurred. Sequence
abort may occur during any pattern mode in preparing a pattern sequence and the timing of reading the
status. Additional status reads may be needed to get a correct state of this indicator. If the box continues to
be checked, check for an error condition in the pattern sequence. Also check that the cumulative exposure
time is not greater that the frame time.
Sequence Error – The box is checked whenever a sequence error has occurred. Sequence errors may occur
during any of the pattern modes in preparing a pattern sequence and the timing of reading the status. The
user may need to perform additional reads of the status to get a correct state of this indicator. If the box
continues to be checked, check for an error condition in the pattern sequence.
DMD Micromirrors Parked – The box is checked whenever the DMD micromirrors are parked.
Sequencer Running – The box is checked whenever the sequencer is running.
Video Running – The box is checked whenever video is running normally.
Locked to External Source – The box is checked to indicate that the EVM has locked to an external parallel
RGB video source. If the EVM loses the locked signal at any time, the box becomes unchecked. A locked
source must be present to switch to Video Pattern Mode.

Operating the DLP LightCrafter Dual DLPC900 EVM
Within the System Settings panel, the user can control the orientation of the image, the LEDs, and the optical
inversion.
•
•
Image Orientation – Depending on the orientation of the projected image, the image may require to be flipped
on its short or long axis.
– The East/West setting causes the image to be flipped on its long axis.
Note
The Dual Controller EVM East/West flip is permanently set to on due to the dual controller
implementation. Reverse pattern data in the images prior to loading or in the video data prior to
loading or streaming video.
– The North/South setting causes the image to be flipped on its short axis. This setting must be set before
any Pattern LUT updates are sent to the DLPC900 and the pattern sequence must be in the stopped
state.
LED Controls – The LED controls allow the user to manually control the state of the LEDs or allow the
internal DLPC900 sequencer to control them.
Note
If the LEDs are disabled in manual control, they must be enabled before switching to automatic
control (internal DLPC900 sequencer).
The LED current regulates the brightness of the LEDs. Setting the Invert PWM causes the LED currents
to have an opposite effect on the LEDs as the current is changed. When manipulating the LED frequency
and current, it is best to think of the led current value from 0-255 (0.39% per step) as the duty cycle where
255 equals ~100% (99.61%) Internally the software then calculates the PWM value depending on the set
frequency and duty cycle. Setting the Invert PWM changes the polarity of the PWM signal which causes the
LED currents to have an opposite effect on the LEDs as the current is changed.
•
•
Note
DLP LightCrafter Dual DLPC900 EVMs do not come with LEDs or optical engines of any kind.
Pattern Display Invert Data – This setting allows the user to invert the data to the DMD. The setting must
be set before any Pattern LUT updates are sent to the DLPC900 and the pattern sequence must be in the
stopped state. This setting is not applicable to Video Mode.
DMD Park – This setting allows the user to park and un-park the DMD. Using the isolated Park/Unpark
command is no longer recommended except for debugging purposes. If the Display Mode is set to Pre-stored
pattern mode, Video pattern mode or Pattern On-The-Fly mode, the pattern sequence must be stopped prior
to execution of this command.

The Pattern Mode panel allows the user to create a pattern sequence. First the user must choose the operating
mode by selecting which of the three pattern modes to use. The three pattern modes are:
1. Pre-Stored Pattern Mode. In this mode the patterns are pre-stored in flash memory and loaded into the
internal memory of the DLPC900 by the firmware. The pattern sequences and images must first be defined
before starting the pattern sequence.
2. Video Pattern Mode. In this mode, the images are streamed from the incoming video source. The pattern
sequences must be defined first before starting the pattern sequence.
3. Pattern On-The-Fly Mode. In this mode the patterns are uploaded to the internal memory of the DLPC900
via the USB or the I2C interface. The pattern sequences must be defined first before starting the pattern
sequence. Using USB is preferred for its higher upload speed.

3.6.2 Creating a Pattern Sequence in Pattern On-The-Fly Mode
Pattern On-The-Fly Mode is the easiest and quickest way to create a pattern sequence. Follow these steps to
create a simple pattern sequence using three images
1. Make sure the EVM is powered up and operating correctly, and the Connected radio-button is lit green.
2. Select Pattern On-The-Fly Mode from the Operating Mode group box, and then click the Pattern Design
button so that the large black panel is displayed as shown in Figure 3-6.
3. Click the Add Pattern button in the Menu bar and browse for any three bitmap images from the sample of
images directory. Be sure to select them from the correct image folder for the EVM that is being used. All
three images can be selected at the same time within the open file dialog window. When selecting multiple
files at once, the operating system may not load the images in the same order as they were selected. To add
images in a predefined order, use the Load button. This option loads the images from a text file that contains
the file names of each bitmap in the desired order. Alternatively, you can add the images one at a time using
the Add Pattern button to ensure order. Figure 3-8 shows an example of loading images from a file. The
bitmap images must be located in the same directory as the text file. See Figure 3-9 after the images have
been added.

3.6.3 Creating a Pattern Sequence in Pre-Stored Pattern Mode
Creating a Pre-Stored Pattern sequence is very similar to Pattern On-The-Fly Mode. The difference is that the
patterns are pre-stored in flash memory.
If images are not present in the flash memory, proceed to Section 3.9.1 section to add the images to the
firmware and upload them to the EVM, then return here for steps on creating the pattern sequence.
To start creating a Pre-Stored Pattern sequence, follow the steps in Section 3.6.2 with the only change in step 2.
In step 2, select the Pre-Stored Patten radio-button and then proceed with step 3.

The LUT Editor panel is shown in Figure 3-12 where the column labeled “SNO” (i.e. Sequence Number)
represents the pattern display slot numbers according to the order set (after clicking Update LUT) in the Pattern
Design tab as shown in Figure 3-11. The user can then reorder those patterns by either manually entering the
pattern number of their choice into a row in the “LUT entry” column or loading a text file beginning with the word
“Reorder” followed by the desired numerical pattern slots as shown in Figure 3-13.
Figure 3-12. LUT Editor Panel
The following steps detail an example using the Edit LUT feature with five patterns in Pattern On-The-Fly-Mode:
1. By following the steps similar to Section 3.6.2, load five patterns in Pattern On-The-Fly-Mode as shown in
Figure 3-11.
2. Set the exposure time to 1000000 us for ease of viewing.
3. Set an input trigger on Pattern 3 by checking the Trigger Input box.
4. Set all other user desired pattern property settings.
5. Click the Update LUT button and wait for all patterns to be uploaded to the EVM.
6. Click the Start button to view the pattern display order.
7. Click the Edit LUT button to open the LUT Editor panel as shown in Figure 3-12. This panel initially opens
with an empty "LUT Entry" column.
8. To reorder the patterns, enter a "2" in "LUT Entry" row 1, and subsequently a "1", "3", "4", "0", and "1" as
shown in Figure 3-12 .
9. Click the Stop button to stop the pattern sequence even if it is not currently running.
10. Check the Repeat box for display repetition of the new pattern sequence and then click the Reorder button.

13. Browse to wherever the text file was saved, and open the file in a text editor program as shown in Figure
3-13.
14. Notice at the top of the text file is the word "Reorder" which is required to successfully load a reorder file in
the GUI. If desired, swap any of the pattern numbers to create a new pattern sequence and save the file.
15. Click the Load button and browse for Reorderexample.txt.
16. Click the Start button to view the new pattern display order.
17. Click the Stop button to stop the pattern sequence.
18. Click the Back button to return to the Pattern Mode tab.
Note
When using the GUI interface, each pattern carries several items of information corresponding to the
slot that it was inserted in the original LUT order. Therefore, when reordering a pattern to a different
slot in the LUT, it retains its original assigned bit information, timing (exposure and dark time), LED
color, and trigger information and NOT the information that is located in its reassigned slot in the LUT.
For example, if pattern 3 contains a trigger input to begin the user’s execution in Figure 3-11 and is
reordered to slot 2 as shown in Figure 3-12, the trigger input is now located at slot 3 in the LUT rather
than slot 0.
In Pre-Stored Pattern Mode, reordering the LUT does not change the pattern locations as it does in
Pattern On-The-Fly Mode. Only the requested bit information, timing, color, and trigger information
are reordered based on the user’s updated LUT. However, it is possible to manipulate the pattern
information after reordering the sequence by manually editing the batch file commands uploaded to
the EVM rather than using the GUI.
Figure 3-13. Reorder Example
It may be helpful to understand the Edit LUT feature by giving names to the patterns, as shown above the
patterns in Figure 3-11, and treating them as the batting order in a baseball game. This way, it is easier to picture
the distinction between the slot order numbers in the "SNO" column (the new batting order) and the patterns
that are inserted into the "LUT Entry" column (the batters). For example, Bob retains his batting statistics
independent of his batting position (i.e. bit information, timing, color, trigger), so if he originally bats first (slot 0
in Figure 3-11) but is moved to fifth in the new batting order (reorder LUT entry 4 in Figure 3-12) he retains all
of his properties. The only difference is that now he does not bat (i.e. is not displayed) until after the four batters
(patterns) preceding him (Sue, Joe, Matt, and Sam). Notice also that in our example Joe bats twice in the new
batting order (SNO 2 and 5). There is only one Joe, who bats twice in the new batting order. In the same way, a
pattern in the original pattern list can be displayed in many positions in the reordered display LUT, without adding
or removing any patterns in DLPC900 memory. Therefore in terms of the system memory, it is only changed
when using the Update LUT feature but never when using the Edit LUT (Reorder) feature in the Figure 3-11.
3.6.4.1 Special Considerations for Input Triggers when using the Edit LUT Feature
Input triggers have some special considerations when using the new Edit LUT Feature. As previously noted,
Pattern 3 (“Matt”) has an input trigger associated with it. When a trigger is added to a pattern, the pattern

Operating the DLP LightCrafter Dual DLPC900 EVM
www.ti.com
preceding it, Pattern 2 (“Sue”) in this case, has an all-black pattern loaded at the very end of it so that while the
sequence is waiting for the trigger it does not have a pattern displaying during the wait. This attribute follows
Pattern 2 during a reorder. In our example the first entry (Pattern 2) in the new display order has a 105 µs dark
pattern at the end of it. If Pattern 0 ("Bob") is placed in front of Pattern 3 ("Matt" - the triggered pattern) then the
last bit-pattern of Pattern 0 (“Bob”) continues to display in our new display order while waiting for the trigger in
Pattern 3 (“Matt”).
The unwanted trigger behavior can be compensated for by one the following methods:
•
•
Method 1: Consider Pattern 2 and 3 ("Sue" and "Matt") as a set that must always be moved together in your
new display order.
- Method 1 is the simplest, but the tradeoff is that these two patterns are not separable without the
undesired trigger behavior described above.
Method 2: Add a 1-bit all-black pattern with the shortest duration allowed (105 µs) preceding the trigger
pattern. Now consider this pattern and the triggered pattern following it as a set that must always be moved
together.
- Method 2 is more versatile, but the pattern set must always contain a triggered pattern.
•
Method 3: Add a 1-bit all-black pattern with the shortest duration allowed (105 µs) followed by a triggered
1-bit all-black pattern (also with 105 µs duration), and remove the trigger from the actual pattern of
interest. These two patterns are now a versatile trigger set that can be used repeatedly wherever a trigger
is desired. Note that since the triggered pattern is black, even if your exposure integration begins with the
triggered black pattern there is no light contributing to your exposure.
- Method 3 is the most versatile since this standalone trigger set only has to be placed in the Pattern Index
set (on the Pattern Mode page) once but can be used in many positions when defining a new display
order.
3.6.5 Creating a Pattern Sequence in Video Pattern Mode
Creating a Video Pattern Mode sequence is also similar to Pattern On-The-Fly Mode. The difference is that the
patterns are streamed from the input video source. The user must create the video images and then input them
through the RGB parallel interface. The input video source vertical sync is used as the triggering mechanism.
The input video source must be stable and locked and continuously being applied, otherwise the firmware
detects that the source was lost and a solid curtain is displayed. While the video source is stable and locked, the
status box for Locked to External Source remains checked.
Follow these steps to create a Video Pattern Mode sequence.
1. Make sure the EVM is powered up and operating correctly, and the Connected radio-button is lit green.
2. Select Video Mode from the Operating Mode group box, and then select the HDMI radio-button from the
IT6535 Receiver group box and finally click the Set button. (Select the DisplayPort radio-button if using this
input connector). The Locked to External Source status box is checked after a few seconds.
3. Verify the video source is displayed. If no video source is displayed, then make sure the PC or host is
supplying the correct resolution and frame rate. See Section 3.5.1 for video support.
4. Select Video Pattern Mode from the Operating Mode group box, and then click the Pattern Design button so
that the large black panel is displayed as shown in Figure 3-6.
5. Click the Add Pattern button on the Menu bar and add 3 patterns. [Hover over buttons in the Menu bar to
see their tool tip]
6. Click the Select All Patterns button to select all images.
7. Set exposure time to 1215 µs and dark time to 0 µs.
8. Select the first image and select a bit depth of 2, start bit G0, and color Green.
9. Select the second image and select a bit depth of 4, start bit R0, and color Red.
10. Select the third image and select a bit depth of 3, start bit B0, and color Blue
11. Click the Select All Patterns button.
12. Remove the check from the Frame Change box.

3.6.6 Creating a Pattern Sequence With DMD Block Load
Creating a pattern sequences with DMD Block Load achieves higher pattern rates by using a subset of the
DMD blocks. See DMD Block Load command in the DLPC900 Software Programmer’s Guide (DLPU018) for a
description of this command.
Follow these steps to create a Pattern On-The-Fly pattern sequence with only three DMD active blocks.
1. Make sure the EVM is powered up and operating correctly, and the Connected radio-button is lit green.
2. Select Pattern On-The-Fly Mode from the Operating Mode group box, and then select the Pattern Design
button so that the large black panel is displayed as shown in Figure 3-6.
3. Select the Load button from the menu bar and select the Block_Load.txt file located in the sample images
directory. Be sure to select the correct file for the EVM being used.
4. The pattern design looks similar to Figure 3-15.
5. Select the Pattern Settings button.
6. Within the DMD Active Blocks, select 6 for the Start Block and select 8 for the End Block, and then Select
Set.
7. Select the Pattern Design button.
8. Select the Update LUT button.
9. Select the Start button to run the sequence. The system only loads data in blocks 6, 7, and 8 regardless of
the thumbnail image shown in the Pattern Design window and displays each pattern for 180,000 μs.
10. Select the Stop button to end this example.
Notice that pattern 0 is displayed the same way as pattern 2 even though pattern 0 contains image data for all
blocks showing that only blocks 6, 7, and 8 are active while all other blocks are in the off state.
Note
The performance of the mirrors in the blocks that are not active are affected by prolonged use of
being in the off state. Enable DMD Idle Mode as often as possible to optimize the mirrors. This mode
provides a 50/50 duty cycle across the entire DMD mirror array, where the mirrors are continuously
flipped between the on and off states. See DMD Idle Mode command in the DLPC900 Software
Programmer’s Guide (DLPU018) for a description of this command. The DMD Idle Mode command is
located in Section 3.6.7 within the Pattern Mode panel.

3.6.7 Pattern Settings
To configure the output or input triggers click the Pattern Settings button as shown in Figure 3-16. Within this
panel, the user can select the output delays of Trigger 1 and 2 and the input delay for Trigger In 1 and 2. The
output delays are from the start of the pattern on the DMD.
Trigger In 1 and 2 can be delayed to have a later affect from when the external device performed the trigger. All
signals can be inverted.
The LED controls can also be delayed. These delays are from the start of the pattern on the DMD.
Minimum LED Pulse Width control allows the system to have much higher pattern speeds. Input the minimum
LED Pulse Width specific to your illumination system to achieve higher pattern speeds through illumination
modulation. Illumination modulation occurs with 8-bit patterns at rates faster than 1031 Hz, by modulating the
light source to shorten the shortest bits, therefore increasing the maximum pattern speed. The LED enable
signals from the DLPC900 can be used to control the illumination modulation of the LEDs.
The DMD Active Blocks allows a subset of DMD blocks to be activated, while the mirrors in the non-selected
blocks are set to the off state. See Section 3.6.6 for an example of using this mode. When operating with a
subset of DMD blocks, enable the DMD Idle Mode as often as possible. For example, whenever the system
is idle, between exposures if the application allows for it, or when the exposure pattern sequence is stopped. To
enable the DMD Idle Mode, the pattern sequence must be stopped. To restart the pattern sequence, the DMD
Idle Mode must be disabled.
Note
To resume operation after disabling DMD Idle Mode issue an Update LUT command.
The DMD Idle Mode provides a 50/50 duty cycle across the entire DMD mirror array, where the mirrors are
flipped between the on and off states to optimize the performance of the mirrors.
The Image Compression option allows for control of the compression type that occurs to the pattern images.
• The Uncompressed option does not attempt to compress the images.
• The Run Length Encoding (RLE) option is a lossless compression method that compresses the pattern data
using horizontal pixel similarities.
• The Enhanced RLE option is a lossless compression method that compresses the pattern data using vertical
and horizontal pixel similarities.
• The Auto option is capable of doing all three compression types and selects the method that takes up the
smallest amount of data
More information on these compression types can be found in the DLPC900 Programmer's Guide.

3.7 Batch Files
Click the Batch Files button at the top of the GUI to display the Batch Command Sequence panel as shown
in Figure 3-17. If the Enable Command Logging box is checked, the panel displays all the commands the user
clicks on the GUI. When clicking the Save Batch File button, the content that is in the panel is saved to a text
file containing the command descriptor followed by the command data. This batch file can then be re-loaded at a
later time using the Load Batch File button and executed or it can be added to the firmware to be executed using
the Batch files Stored in the EVM group box. This group box lists all the batch files currently in the firmware.
Figure 3-17. Batch Files Panel
3.7.1 Execute Batch File
The DLPC900 firmware has the option to store batch files within the firmware. These batch files contain
commands that are executed to perform some sequence of settings without the user or host performing these
commands. If the firmware contains batch files, the GUI queries the batch file names and list them in the Batch
Command Sequence panel within the Batch Files Stored in the EVM group box. The user can then choose a
batch file from the list to execute it.
The user can also designate a default batch file to be executed during the DLPC900 power-up sequence when
the power is applied. For example, if the LEDs are to remain off after power has been applied to the EVM, a
batch file can be created with the commands to turn the LEDs off, and then update the firmware with this batch
file as the default. The updated firmware can then be uploaded to the EVM. The next time the power is applied
to the EVM, the LEDs are disabled from turning on. See the DLPC900 Programmer's Guide for the batch file
commands in Appendix B for a complete list of commands that can be used within a batch file.

3.9 Firmware
Click the Firmware button to display the Firmware panel as shown in Figure 3-20. In this panel a user can update
the firmware with patterns, batch files, and set start-up conditions.
Before uploading firmware, verify the EVM is powered-up, operating normally and connection has been
established with the GUI. To update the firmware on the EVM click the Browse button and locate the firmware file
for the EVM type. Then click the Upload button.
Within the Power up Defaults group box, a user can select the default power-up state by checking the Startup
State checkbox and then selecting the state from the drop-down list box.
If the IT6535 digital receiver is present on the hardware, then the user may enable the use of this receiver by
checking the HDMI/DP Receiver checkbox.
If a default batch file is needed, then see the Batch File section in this guide.
The DLPC900 can also be controlled over the I2C interface on I2C port 0. The default DLPC900 secondary
address is 0x34. This address is programmable using the I2C secondary address within the Power up Defaults
group box.
The GUI permits the user to perform a bus swap on the DMD by checking the DMD Bus Swap box and selecting
between Channels A and B. This feature is a firmware configuration option that only takes effect after uploading
the firmware onto the EVM. However, when using the DLP LightCrafter Dual DLPC900 EVM the user may
perform a bus swap on both the primary and the secondary by selecting each checkbox per desired channel.
The GUI also permits the user to enable Spread Spectrum Clock Generator Support. The user can select
from .5%, .75%, or 1% in the drop down menu. This option uses internally controlled clock spreading to help
minimize EMI due to high-speed signals. More information on the spread spectrum feature and DMD bus
swapping can be found in the DLPC900 datasheet.

Figure 3-20. Firmware Panel
3.9.1 Adding or Removing Patterns from the Firmware
For most efficient storage and compression of images, the GUI packs the images into groups of 24-bit RGB
bitmap images. If there are 1-bit black and white images, 8-bit gray scale images, or any other image bit-depth
(up to 24-bit images), they are combined to create a composite image. For example, a composite image
composed of 24 1-bit images, 3 8-bit images, or a combination of images of various bit-depths which add up to a
24-bit composite image.
Note
An image cannot span two 24-bit composite images. For example three 7-bit images can fit in a
composite 24-bit image, but a fourth 7-bit image must go into a separate 24-bit image. Only a 3-bit or
smaller image can be put into the remaining bits of the first composite 24-bit image.
The GUI then compresses each 24-bit image using the Enhanced Run-Length Encoding described in the
DLPC900 Programmer's Guide. These compressed images are then decompressed as they are loaded into the
DLPC900 internal memory when operating in Pre-Stored Pattern Mode or Pattern On-The-Fly Mode.
The EVM is capable of holding up 400 1-bit binary or 50 8-bit binary compressed patterns in flash memory.
Depending on the compression ratio, more than 400 patterns can be stored to have multiple pattern sets for
multiple pattern sequences. These patterns are then loaded when the operating mode is set to Pre-Stored
Pattern Mode. The remainder of this topic applies only to Pre-Stored Pattern Mode.

Operating the DLP LightCrafter Dual DLPC900 EVM
www.ti.com
The DLP LightCrafter Dual EVM can be loaded with a pattern sequence that is displayed when power is applied
to the EVMs. Since the GUI does not know the images that are stored in flash memory, it is advisable to delete
all images from flash before storing new ones.
When adding images to the Pattern Design panel, the GUI always begins with image index Zero. However, the
GUI saves the images to the firmware by appending them to the end of the last image that is in the firmware if
any.
For example, if there are two 24-bit images stored in the firmware. These two images have index values of 0
and 1. Then if a pattern sequence is created in the Pattern Design panel, where the GUI packs all the images
into four 24-bit images, and then saved to the firmware, the four images are appended to the firmware and have
index values of 2, 3, 4, and 5. When the firmware is uploaded to the EVM and the pattern sequence is started,
the sequence of images is 0, 1, 2, 3 rather than 2, 3, 4, 5.
First begin by examining the images that are currently in the firmware.

Click the Source Select drop-down list box, and select Images From Flash.
Below the Source Select drop-down list box, select 0.
Click the Set button.
Continue to index through all the values until a new image is not displayed. This means you have reached
the end of the stored images.
The index value reached (plus one) represents the number of images that are stored in flash.
Return to the video source by selecting the Parallel RGB interface from the Source Select drop-down list box
and click the Set button. If there is a video source connected to the EVM, the source is displayed, otherwise a
solid curtain is displayed.
3.9.1.1 Deleting Images
When deleting images from flash, the flash device is erased and then updated with the firmware that contains
the new images. In the event the flash is accidentally corrupted, follow the instructions under JTAG Flash
Programming (see Section 3.11) to reload the original firmware. To remove accidental erasing or corruption of
the flash device, it is recommended to operate in Pattern On-The-Fly Mode.
CAUTION
The user must exercise caution when selecting the correct firmware file. Ensure that firmware file is
version 3.0 or later. (Using version 2.0 or earlier renders the EVM inoperable).

Note
When a firmware file is uploaded, a cached version of that file is created on the PC in its original
folder location. Each time a new firmware is uploaded the GUI compares it to the cache file on
the PC and only reprogram the new sectors. The cache file is then updated to represent the latest
firmware image. This can lead to significant download speed improvements if the new firmware
and the previous firmware are similar.
Note
If a full reprogramming of the flash is desired, the user can delete the cache folder or
select a firmware image from a different file location.

3.10 Flash Device Parameters
For EVM use with several different flash memory parts, the user can edit the FlashDeviceParameters.txt file
to match the flash memory part that has been installed with the EVM. This file is located in the DLPC900REFSW-x.x.x\DLPC900REF-GUI\Flash directory of the DLPC900REF-SW bundle. An example with the Infineon
S70GL02GS2 part is shown in Figure 3-23 where the user comments out all lines EXCEPT for the top line which
includes the chosen Infineon flash part. More detailed information can be found in the comments at the top of the
text file.
Figure 3-23. Flash Device Parameters Text File
3.11 JTAG Flash Programming
The DLPC900 JTAG Programmer Tool is included in the DLPC900REF-SW bundle allowing a user to program
the bootloader image into the flash using the JTAG boundary scan connector if, for example, the bootloader
becomes corrupted and the board is rendered inoperable. The tool can also be used for updating the entire
firmware image. Programming the entire firmware image using this method may take a long time. It is suggested
to program only the bootloader using this method, and then use the DLPC900 LightCrafter GUI with a USB
connection to upload the entire firmware image. The following steps are for programming only the bootloader
image.
Before using JTAG to reload the bootloader, first install the BOOTHold jumper (J12) and turn the
system on. The system shows connected, but does not recognize the attached DMD. Manually select
the radio button that matches your DMD and go to the firmware tab and select the FW image and
reprogram. Then power down, remove the BOOTHold jumper and restart the system. Reprogramming
in this manner often recovers a system without requiring reloading the bootloader through JTAG.
The DLPC900 JTAG Programmer Tool requires the UM232H module with modifications, which is manufactured
by Future Technology Devices International Ltd (FTDI Chip), . The UM232H module can be purchased from
Digi-key with the following part number: 768-1103-ND. The driver can be downloaded from the FTDI website
(www.ftdichip.com). Select the VCP CDM WHQL Certified driver for Windows.
Make the following modifications to the UM232H and use Figure 3-24 and Figure 3-25 as a guide.
