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

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

www.ti.com

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.

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 (1) Green LED Current (A) = 0.0181 × (LED Current Value) + 0.3587 (2) Blue LED Current (A) = 0.0160 × (LED Current Value) + 0.1529 (3)

Typical performance of the red, green, and blue LEDs are shown in Figure 2, Figure 3, and Figure 4, respectively. Manufacturing processes can lead to variations in LED brightness and current consumption. Actual LED performance might vary from those shown in the following figures.

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 LightCrafter 4500 LEDs.

Typical variations in LED manufacturing can lead to changes in the brightness and current consumption. Thus for typical white balance point, TI recommends the following percentages of colors:

• Red or green is approximately 87.5%

• Blue or green is approximately 97.6%

At the default LED current values of:

• Red = 104

• Green = 135

• Blue = 130

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 3-

1 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.

Pattern Sequence Mode

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 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 LightCrafter4500 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 LightCrafter4500 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.

Pattern Sequence Mode

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 Mode

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

To create a pattern sequence, follow these steps:

1. Choose pattern input source (Flash or Video port) from the Pattern Source section.

2. Choose Internal/External, or VSYNC trigger mode from the Trigger Mode section.

3. Set the appropriate Trigger Controls, see Section 3.3.4

4. Set the Pattern Exposure period and Pattern Period.

5. 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.

(ii) Frame Index: This value can be left alone. The patterns will be pulled from the specified bit-

plane(s) from each transmitted video frame sequentially

www.ti.com

Note: In pattern sequence mode, you are not sending a standard 24 bit RGB image, you are sending a group of images in parallel, anywhere from 3 8-bit images (grayscale) to 24 individual 1bit images. 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

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.

Make sure to click the Send button after clicking on Play Once to download the new settings.

6. Clicking the Validate Sequence button executes a data validation and updates the Data Validation

status indicators in this tab. If the data validates successfully, the pattern sequence is downloaded to the DLP LightCrafter 4500 and waits for the Play button to be pressed to start displaying the pattern sequence. If a data validation problem occurs, the appropriate status indicators are highlighted in the Data Validation section:

• Exposure/Period OOR: When highlighted red, the Pattern Exposure period or Frame period is out

of range. The pattern exposure period must be greater than the fastest period supported, as listed 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.

This subtab does an instant calculation on the time the DLPC350 takes to load a full 24-bit RGB bitmap from flash. This measurement is instantaneous and is not the average nor worst-case timing. To get an instantaneous measurement, perform the following steps:

1. Select the desired image number from Image Index.

2. Click the Get Load Image Timing button.

The DLPC350 decompresses the 24-bit RGB bitmap stored at the Image Index location and loads it to the internal buffer. The time required for this process is displayed in milliseconds. This feature overwrites the images currently in the display buffer.

Figure 3-8. Image Load Timing

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.

3.5 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.

Underneath these selections, the left-hand window shows a preview of the Input file. The right-hand window shows a preview of the 24-bit output file that has taken all the input files and bit weighted the added images according to the bit-plane position requested. Images added at bit position B0 to B7 show blue, bit position G0 to G7 show red, and bit position R0 to R7 show green. This is due to the DLPC350 display order being GRB (see table 2-69, Pattern Number Mapping, in the DLPC350 Programmer's Guide), whereas BMP images are stored as RGB. For each color, bit position 0 is the least significant bit, while bit position 7 is the most significant bit.

To download the images into flash, a series of 24-bit images must be added to the firmware file using the Firmware Build subtab with the following steps:

1. Select the Image / Firmware tab and the Firmware Build subtab.

2. Select a firmware file by clicking the Browse button next to Firmware File.

Peripheral Control

3.6 Peripheral Control

DLPC350 offers several configurable pins. The Peripheral Control tab of the GUI controls how these pins are configured. The following options are available:

• General Purpose Clock: Two DLPC350 pins can be individually configured as clocks.

• PWM Output Setup: Two DLPC350 pins, GPIO_00 (pin 18 in J6) and GPIO_02 (pin 22 in J6), can be individually set as PWM outputs.

• GPIO Configuration: Several DLPC350 pins can be individually configured as GPIO. Once configured as GPIO, the Pin Direction (Input or Output), if set to output the Pin State (High or Low) and output type (open drain output or drive high or low), can be configured. Some GPIO pins are already configured by the firmware for specific functions and these are listed with their current configuration.

• PWM Capture Setup: Two DLPC350 pins, GPIO_05 (pin 14 in J6) and GPIO_06 (pin 17 in J6), can be individually set as PWM inputs. These pins will sample at the frequency specified in PWM Sample Rate and report the duty cycle of the input signal.

• I2C0 (Master) Read/Write Control: The DLPC350 master I2C0 port can be accessed via the J16 connector on the LightCrafter4500. This section provide control over this port. The hex addresses and data should be in the format <value><space><value><space>... For example: 0x22 0x11. The number for bytes to be read is input as a decimal value.

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.

Chapter 4

DLPU011E–July 2013–Revised September 2015

Pattern Sequences

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. Bit Partition

Pattern Sequences DLPU011E–July 2013–Revised September 2015

Submit Documentation Feedback

www.ti.com

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.

Pattern Sequence Background

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.

Pattern Sequence Background

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.

www.ti.com

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.

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, you must build the .ini file 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

DLPU011E–July 2013–Revised September 2015

Saving Solutions

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.

Before saving an .ini to firmware, TI recommends first applying the solution. Wrong values or incorrect syntax can potentially damage the DLP LightCrafter

4500.

5.3 Modifying .ini Files

There are two ways to modify the .ini files. The first method is to use the Save Solution button on the GUI. The second method is to open the .ini file in a text file editor and edit it manually.

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 your .ini file.

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.
