DLP LightCrafter (DLP3000-C300REF) Reference Design: Technical Features

RGB LED light engine with 20L light output.

  • High speed patterns using the native DLP3000 resolution (608x684)
  • Up to 4kHz binary pattern rate
  • Up to 120Hz 8bit greyscale pattern rate
  • Display images or video up to WVGA resolution (854 x 480)
  • Configurable I/O trigger for synchronising with cameras, sensors, etc.
  • DM365 embedded processor running embedded Linux
  • 128MB NAND flash memory for pattern and sequence storage
  • USB, Mini HDMI, UART interfaces
  • USB-based API and host GUI
  • Compact size: 117mm x 65mm x 23mm

  • The device is a sandwich of two boards on a metal base. Next to it, there is an optical module with an emitter connected to the boards with flexible cables. The metal base also serves as a heat sink. The products structure is reliable and practical. All the necessary connectors are located along the perimeter and on top. Basically, it is the way it should be for devices like this.



    The EVM module includes a CPU board, a driver board and a light emitter. DM365 is the multimedia processor TMS320DM365 based on the DaVinci technology by Texas Instruments. It is used for launching Embedded Linux. FPGA is Altera Cyclone IV FPGA; it controls the mixing of video channels (HDMI or DM365), the switching of LEDs and internal buffers for fast display of patterns. DLPC300 is a DMD controller. MSP430 controls power and LED drivers.



    Power can be supplied directly to the computer USB (preferably from a separate power supply) through connection to the jack on the DC_IN lower board.

    The debug UART is connected to Minijack 2.5, but, for the lack of it, we just soldered in to it (red wires in the yellow cambric). MiniUSB is a standard cable. HDMI through MiniHDMI/HDMI.

    Bring up


    Texas Instruments provides a cross-platform graphic EVM utility, which displays images and video from a camera / HDMI, as well as helps update embedded software.

    There is also an example of a command line provided by API.
