3.2 Creating A Simple Pattern Sequence

Before creating a pattern sequence, make sure to follow the steps in Section 3.1. 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 4-7 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 3-1.
  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\DLPC900REF-SW-5.x\DLPC900REF-GUI\Images and Batch files\[DMD]_Images. Be sure to select them from the correct image subfolder for the EVM that is being used. All three images can be selected at the same time within the open file dialog window, but do 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 3-2 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 100000µs, dark time to 50000µs, and select Red for the color.
  4. Select the second pattern and choose a bit depth of 1. Set exposure to 150000µs, dark time to 75000µs, and select Green for the color.
  5. Select the third pattern and choose a bit depth of 1. Set exposure to 200000µs, dark time to 100000µs, and select Blue for the color. Figure 3-2 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.
