QT is a Nokia cross-platform application and user-interface framework with open source and commercial licenses.
  • Page 25: System Status

    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.
  • Page 26: Operating Mode

    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.

The DLPC350 treats these as video inputs and applies image processing functions, like scaling, gamma correction, color coordinate adjustments, and so forth.
  • Page 30: Pattern Sequence Mode

    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.
