1.3 DLP LightCrafter Embedded Software Overview

1.3.1 DM365 Software

The DLP LightCrafter module software is based on TI’s DVSDK platform running on the Digital Media System-on-Chip DM365. The DVSDK platform is a collection of royalty-free software components built upon Linux operating system and pre-tested by TI. The software components include Linux kernel, Linux filesystem, Linux product support package (PSP), application framework (APIs), codec libraries (MPEG4, H.264, MPEG2, G.711, JPEG), example programs, DSP Codegen, and CodeSourcery tool chain with IDE for cross-compiling and debugging target systems.

DLP LightCrafter Embedded Software Overview

Out of the box, the DLP LightCrafter boots from the on-board NAND FLASH. The DM365 acts as the main processor of the system and boots as an embedded Linux device. The Linux file system resides on the NAND or micro-SD card. Thus, the DLP LightCrafter does not require an NFS mount nor a TFTP server to run. The embedded Linux system utilizes Remote Network Drivers Interface Specification (RNDIS) to send packets through USB. DLP LightCrafter has a default IP address of 192.168.1.100.

1.3.1.1 Serial Communication

DLP LightCrafter’s UART port serves as a console output of the embedded Linux device. The DM365 sends error messages through the UART and accepts root level commands. A 2.5-mm stereo plug to female DB9 connector is needed to connect the DLP LightCrafter’s UART port to a PC. For PCs with only USB ports, use a USB-to-serial RS232 adapter.

To view UART console messages, configure a terminal emulator with the following parameters:

• Baud: 115200

• Data Bits: 8

• Stop Bits: 1

• Parity: None

• Flow Control: None

1.3.2 FPGA Overview

The FPGA expands the functionality of the DLP 0.3-inch WVGA chipset to enable the features of DLP LightCrafter. An important feature of DLP LightCrafter is the ability to display stored patterns at high frame rates. The FPGA provides the timing and signal management to implement a four buffer rotation scheme, which enables a stored pattern capability of 4x24=96 binary patterns. Additional capabilities include:

• An external trigger input, which allows an external device to trigger stored patterns; configurable for polarity (positive or negative), delay, and duration (pulse width).

• An external trigger output, which provides the ability to synchronize an external camera with the display of patterns; configurable for polarity (positive or negative), delay, and duration (pulse width).

Figure 1-5. DM365 DVSDK Software Platform

DLPU006C–January 2012–Revised December 2013 DLP®LightCrafter™ Module Overview

DLP LightCrafter Embedded Software Overview

• A timing generator, which implements the internal auto trigger for continuously repeated pattern display.

• Control for the illumination LEDs; generates LED strobe signals with configurable delay and duration to set exposure; synchronized with the trigger.

• A video data source input selector (MUX); sends the video data to the DLPC300 parallel input. Inputs are:

– Video from the TFP401A DVI receiver – DM365 24-bit RGB (not bit identical with stored patterns) – DM365 YUV4:2:2 video converted to RGB888 (bit identical with stored patterns).

• Timing and signal management for a "circular" frame buffer.

1.3.3 MSP430 Overview and Shutdown Protection Modes

The MSP430 controls the power sequencing, initializes the DLPC300, and provides safety shutdown protection modes for DLP LightCrafter. The MSP430 has three shutdown protection modes. The shutdown modes require that both the system power and USB cable be disconnected before a reboot is allowed. Each mode is displayed by blinking the Red LED (D3) on the driver board at different rates. Table 1-2 describes the protection modes.

This chapter describes installing the Graphical User Interface (GUI), controlling the DLP LightCrafter Module using the GUI, and upgrading the firmware on the EVM. All instructions relating to the GUI in this document refer to the latest DLP LightCrafter GUI v5.0.

2.1 Installing the GUI

DLP LightCrafter includes a QT-based GUI to control the module through USB. QT is a Nokia crossplatform application and user interface framework with open source and commercial licenses. To install the DLP LightCrafter GUI, follow these steps.

1. Download the most recent version of the DLP LightCrafter Software Bundle from

http://www.ti.com/tool/dlplightcrafter.

• Linux users will also need to install the latest QT version 5 library. Available from http://qt-

project.org/downloads. After the QT library has been installed, the user must create a file in the

"etc/ld.so.conf.d" directory so that the GUI coorrectly accesses the QT library. Create a file called "Qt5.conf" in the "etc/ld.so.conf.d" directory and enter the location of the QT5 library directory. For example, "<QtInstall_dir>/5.1.1/gcc/lib". Verify the actual directory path of the "lib" directory in the installed QT5 library. After the file has been saved, run "ldconfig" in the terminal.

2. Extract the files from the downloaded zip file.

3. Run the DLP LightCrafter Software Bundle installer.

• Linux users may need to right click on the installer file and set a property to "Allow executing file as

program" so the installer executes correctly.

• Linux and Mac installers may attempt to install the software bundle to the root directoy, which for

some users may not be accessible. Choosing a different installation directory, such as the user's home or documents folder should allow the installation to run properly.

4. From the GUI directory of the installed software, double click on the LightCrafterGUI application to run the GUI. By default the GUI is installed in one of the following directories:

• Windows XP & 7: "C:\Texas Instruments-DLP\DLPLCRSoftwareBundle-3.0\LightCrafterGUI-v5.0-

Windows"

• Linux: ".../Texas Instruments-DLP/DLPLCRSoftwareBundle-3.0/LightCrafterGUI-v5.0-Linux"

– Linux users may need to right click on the GUI executable file and set a property to "Allow

executing file as program" so the GUI operates correctly.

• Mac: ".../Texas Instruments-DLP/DLPLCRSoftwareBundle-3.0/LightCrafterGUI-v5.0-Mac"

2.4 Setting the LED Current

The DLP LightCrafter uses current drivers to individually control the current through each LED using an integer current value. The LED current is computed as follows:

LED Current (mA) = 1.8 × (LED Current Value) + 140 (1)

When at room temperature, the maximum value allowed is dependent on the cooling system of the DLP LightCrafter. The passively cooled systems of the DLP LightCrafter (no extra heat sinks or fans) have a thermal limit resulting in LED currents under 633 mA. DLP LightCrafter actively cooled systems (extra heat sink and fan) have a thermal limit resulting in LED currents under 1.5 A. Table 2-1 summarizes these constraints. Figure 2-26 shows the "LED Current" settings in the GUI.

2.8.1.1 Hardwired Pattern Sequences

The DLPC300 can generate a set of 15 vertical 1-bit monochrome patterns with its internal pattern generator. These patterns are called hardwired patterns in the DLP LightCrafter GUI. Up to 32 of these vertical patterns can be arranged in any order with or without inversion. The inversion of a pattern converts the black regions to white and the white regions to black. For a description of the available patterns, see Table 2-64 from the DLPC300 Programmer’s Guide, TI literature number DLPU004. Pattern numbers 0 through 10 form a set of gray coded patterns. Pattern numbers 11 through 14 can be used for auto-focus.

1. Submit MBMC pattern sequence requests on TI's E2E forum in the DLP LightCrafter Development Platform subsection (http://e2e.ti.com/) by creating a post titled "MBMC Request" and provide the following information:

• Pattern Exposure time (250 µs < PExT ≤ 20000 µs).

– This parameter influences the maximum bit-depth possible in the sequence for each pattern.

For example, if the exposure time is 1000 µs then it is only possible to have 1-bit or 2-bit depth patterns. On the other hand, an exposure time ≥ 8333 µs supports patterns of all bit-depths from 1 to 8. See Table 4-3 to find the minimum exposure time for each pattern’s bit-depth.

• Patterns Sequence Information as shown in Table 2-3.

– Patterns must be listed in the order to be displayed. – Depending on the order of patterns with different bit-depths it is possible that there will be

unused bit-planes that still count towards the maximum 96 bit-planes. The system will not allow split multiple bit-depth patterns across the 24-bit frame buffer boundaries. For example, in the 1st row of Table 2-3, there are five, 5bpp patterns. This would translate to 5 x 5 = 25 individual bit planes, but each frame buffer can only accommodate 24 individual binary frames. Therefore, in a pattern sequence of five, 5-bit patterns, 20 reside in the first frame buffer, while the last 5bit plans reside in the next frame buffer. The 5bpp x 5 pattern set actually consumes 29 individual bit planes of the frame buffer:

• 5bpp × 4 patterns + 4 unused patterns = 24 patterns (from the first frame buffer)

• 5bpp × 1 pattern = 5 patterns (from the second frame buffer)

• Results in 24 + 5 = 29 individual binary patterns.

This chapter describes the pattern sequences supported by the DLP LightCrafter Module

4.1 Pattern Sequence Background

The DLPC300 device takes as input 16-, 18-, or 24-bit RGB data at up to 60-Hz frame rate. This frame rate is composed of three colors (red, green, and blue) with each color equally divided in the 60-Hz frame rate. Thus, each color has a 5.55 ms time slot allocated. Because each color has 5-, 6-, or 8-bit depth, each color time slot is further divided into bit-planes. A bit-plane is just one-bit representation of all the pixels in the image. A 24-bit image is decomposed into its bit planes in Figure 4-1.

Chapter 4

DLPU006C–January 2012–Revised December 2013

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 illustrates this partition of bits in a frame.

Figure 4-2. Relationship Between Bit Partition and Time

Therefore, a single video frame is composed of a series of bit planes. Because the DMD mirrors can be either on or off, an image is created by turning on the mirrors corresponding to the bit set in a bit plane. With the binary pulse-width modulation, the intensity level of the color is reproduced by controlling the amount of time the mirror is on. For a 24-bit RGB frame image inputted to the DLPC300, the DLPC300 creates 24 bit planes, stores them on the mDDR, and sends them to the DLP3000 DMD, one bit plane at a time. Depending on the bit weight of the bit plane, the DLPC300 device controls the time this bit plane is exposed to light, controlling the intensity of the bit plane. To improve image quality in video frames, the bit planes, time slots, and color frames are intertwined and interleaved with spatial-temporal algorithms by the DLPC300 device.

For other applications where this image enhancement is not desired, the video processing algorithms can be bypassed and replaced with a specific set of bit planes. The bit depth of the pattern is then allocated into the corresponding time slots. Furthermore, an output trigger signal is also synchronized with these time slots to indicate when the image is displayed. For structured light applications, this mechanism provides the capability to display a set of patterns and signal a camera to capture these patterns overlaid on an object.

4.2 External Patterns

Using the mechanism described in the previous section, an external device can feed patterns to the DLPC300 for display. Figure 4-3 illustrates the bit planes and corresponding output triggers for 3-bit, 6-bit, and 12-bit RGB.

External Patterns

Figure 4-3. Bit Planes and Triggers

While an external device is writing a frame to the DLPC300, the previous frame is displayed. Therefore, there is a lag of one video frame in relation to the output trigger signal.

Internal Patterns

4.3 Internal Patterns

In addition to the externally provided sequences through the 24-bit RGB interface of the DLPC300, the DLP LightCrafter offers the ability to pre-load patterns into the DLPC300’s memory (mDDR) to achieve faster frame rates. Once the patterns are pre-loaded, the FPGA manages the bit planes stored in the mDDR. The mDDR accommodates four 608 × 684 images of 24-bit RGB data or 96 bit-planes (24 bitplanes × 4 images). The 96 bit-plane buffer is arranged in a circular buffer style, meaning that the last bit plane addition to the buffer replaces the oldest stored bit plane.

The oldest set of bit planes in the bit-plane buffer is displayed. Thus, the displayed patterns will lag by

16.66 ms at 60 Hz frame rate while the circular buffer is filled. After the initial 16.66-ms delay, there is no

additional delay for subsequent patterns since the circular buffer is filled. With the FPGA, the pattern frame rate can be calculated with the following equation:

Pattern Rate = (1/Pattern Exposure Period) + (Bit Plane Load Time) + (Buffer Rotate Overhead)

where

• Typical bit plane load time = 230 µs

• Typical buffer rotate overhead = 135 µs (2)

Table 4-2 shows the maximum pattern rate that can be achieved by using a single FPGA’s internal buffer

in continuous mode.

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